# Summary for NSPIRES {#summary-for-nspires .unnumbered}

The goal of the proposed work is to strengthen ARCTAS's ability to
achieve the objectives of its Theme 3, Aerosol Radiative Forcing
(including indirect aerosol forcing via clouds) and its Theme 2, Boreal
Forest Fires, by providing scientific coordination. The coordination
will also contribute to ARCTAS Theme 1, Long-Range Transport of
Pollution to the Arctic, and its Theme 4, Chemical Processes.
Coordination will focus on the NASA P-3, which is now planned to fulfill
the roles of the aircraft described as the J-31 in the ARCTAS call
(ROSES 2007 A.13) and as the smaller profiling aircraft in the ARCTAS
White Paper. Coordination will emphasize using the P-3 in concert with
A-Train and other satellites (including Aura, Aqua, CALIPSO, CloudSat,
PARASOL, and Terra), with other ARCTAS aircraft (DC-8 and B-200),
possibly with aircraft from other agencies (e.g., NOAA P-3, DOE G-1),
and with measurements from ground sites (including measurements of snow
and ice albedo as affected by simultaneously measured soot, and
radiometric and lidar measurements by AERONET, MPLNET, and other
providers, including the DOE North Slope of Alaska site and the
University of Alaska).

Planned coordination services include:

\* Develop an integrated set of ARCTAS scientific objectives for all
instruments on the P-3.

\* Represent instrument PIs in determining the best deployment bases &
schedule to achieve those scientific objectives.

\* Develop an integration and test flight schedule in concert with
instrument PIs and the P-3 operator (NASA Wallops).

\* Coordinate development of generic flight plans before deployment and
of actual flight plans during deployment.

\* Develop a plan that allocates flight hours to scientific objectives
by priority.

\* Provide maps of satellite tracks and areas of sunglint and desired
elevation angles.

\* Serve as flight scientist and/or delegate this flight by flight.

\* Submit a flight report for each flight served as flight scientist.

\* Coordinate with other ARCTAS A/C, ground sites, and satellites.

\* Coordinate post-deployment data workshops, archival, publications,
etc.

\* Lead & participate in integrated analyses, presentations, &
publications.

The above list assumes a P-3 instrument suite consisting of radiometric
sensors, possibly enhanced by in situ aerosol instruments. Envisioned
radiometric instruments include three previously flown on the J-31 and
now planned for use on the P-3 (Ames Airborne Tracking Sunphotometer,
Solar Spectral Flux Radiometer, Cloud Absorption Radiometer), plus
others likely to be proposed for ARCTAS (e.g., broadband flux
radiometers, thermal IR scanner, and rainbow camera). Possible in situ
additions include aerosol instruments previously flown on the P-3, DC-8,
C-130, and other aircraft by the University of Hawaii, NASA Langley, and
other investigators. If in situ sensors are included in the P-3 payload,
scientific coordination responsibilities will be shared with an in situ
instrument scientist.

The proposed coordination will benefit from the PI's experience in
coordinating the J-31 in INTEX-A and -B and in serving as Mission
Scientist for 11 C-130 flights in ACE-Asia, as Co-coordinator for the
ClearColumn experiment in ACE-2 (including the Pelican aircraft), and as
Coordinator for TARFOX (including C-131, ER-2, C-130, and Pelican
aircraft).

# SCIENTIFIC/TECHNICAL/MANAGEMENT SECTION

## Background, overall goal, and general approach

In Spring and Summer 2008 NASA will conduct the Arctic Research of the
Composition of the Troposphere from Aircraft and Satellites (ARCTAS)
campaign, as outlined by ROSES 2007 Appendix A.13 and the ARCTAS White
Paper (Jacob et al., 2007). Figure 1 shows the ARCTAS strategy for
combining satellite and aircraft measurements to improve understanding
of arctic atmospheric composition and climate. The overall goal of the
research proposed here is to strengthen ARCTAS's ability to achieve the
objectives of its Theme 3, Aerosol Radiative Forcing (including indirect
aerosol forcing via clouds) and its Theme 2, Boreal Forest Fires, by
providing scientific coordination services. The coordination will also
contribute to ARCTAS Theme 1, Long-Range Transport of Pollution to the
Arctic, and its Theme 4, Chemical Processes. Our proposed coordination
will focus on the NASA P-3, which is now planned to fulfill the roles of
the airplane described as the J-31 in the ARCTAS call (ROSES 2007 A.13)
and as the smaller profiling aircraft in the ARCTAS White Paper.
Coordination will emphasize using the P-3 in concert with A-Train and
other satellites (including Aura, Aqua, CALIPSO, CloudSat, PARASOL, and
Terra), with other ARCTAS aircraft (DC-8 and B-200), possibly with
aircraft from other agencies (e.g., NOAA P-3, DOE G-1), and with
measurements from ground sites (including measurements of snow and ice
albedo as affected by simultaneously measured soot, and radiometric and
lidar measurements by AERONET, MPLNET, and other providers, including
the DOE North Slope of Alaska site and the University of Alaska).

data to improve understanding of arctic atmospheric composition and
climate. (Source: ARCTAS White Paper)

The coordination services we propose are detailed in Section 1.5. They
assume a P-3 instrument suite consisting of radiometric sensors,
possibly enhanced by in situ aerosol instruments. Envisioned radiometric
instruments include three previously flown on the J-31 and now planned
for use on the P-3 (Ames Airborne Tracking Sunphotometer, Solar Spectral
Flux Radiometer, Cloud Absorption Radiometer), plus others likely to be
proposed for ARCTAS (e.g., broadband flux radiometers, thermal IR
scanner, rainbow camera, and possibly a Research Scanning Polarimeter).
Possible in situ additions include aerosol instruments previously flown
on the P-3, DC-8, C-130, and other aircraft by the University of Hawaii,
NASA Langley, and other investigators. If in situ sensors are included
in the P-3 payload, scientific coordination responsibilities will be
shared with an in situ instrument scientist.

The proposed coordination will benefit from the PI's experience in
coordinating the J-31 in INTEX-A and -B and in serving as Mission
Scientist for 11 C-130 flights in ACE-Asia, as Co-coordinator for the
ClearColumn experiment in ACE-2 (including the Pelican aircraft), and as
Coordinator for TARFOX (including C-131, ER-2, C-130, and Pelican
aircraft).

## Statement of relevance to NASA's strategic goals, objectives, science questions, and the NRA

The research proposed here addresses the following strategic sub-goal,
science questions, and science goals from Table 1 of the ROSES 2007
Summary of Solicitation:

[Strategic Sub-goal 3A]{.underline}: Study Earth from space to advance
scientific understanding and meet societal needs.

[Science Questions]{.underline}:

• How is the global Earth system changing?

• What are the primary causes of change in the Earth system?

• How does the Earth system respond to natural and human-induced
changes?

• How will the Earth system change in the future?

[Research Objectives]{.underline}:

3A.1 Understand and improve predictive capability for changes in the
ozone layer, climate forcing, and air quality associated with changes in
atmospheric composition.

3A.5 Understand the role of oceans, atmosphere, and ice in the climate
system and improve predictive capability for its future evolution.

3A.6 Characterize and understand Earth surface changes and variability
of Earth's gravitational and magnetic fields.

As noted by the ROSES 2007 Summary of Solicitation, NASA addresses these
questions and objectives by using an integrated observational strategy
that combines observations from space with suborbital and ground-based
measurements.

This proposal responds specifically to Appendix A.13 (TROPOSPHERIC
CHEMISTRY: ARCTIC RESEARCH OF THE COMPOSITION OF THE TROPOSPHERE FROM
AIRCRAFT AND SATELLITES) of the ROSES 2007 call, which solicits
proposals for *in situ* and remote-sensing measurements on aircraft in
ARCTAS, for establishing specific satellite calibration/validation needs
for incorporation into aircraft flight plans, and for research plans
that provide for the synthesis of airborne and satellite observations.

## ARCTAS Scientific Themes, Aircraft Platforms, Payloads, Flight Patterns, and Deployments 

As described by ROSES 2007 Appendix A.13 and the ARCTAS White Paper
(Jacob et al., 2007), the ARCTAS observations and sampling strategy will
focus on four scientific themes:

1\. **Long-range transport of pollution to the Arctic** including arctic
haze, tropospheric ozone, and persistent pollutants;

2\. **Boreal forest fires** and their implications for atmospheric
composition and climate;

3\. **Aerosol radiative forcing** from arctic haze, boreal fires,
surface-deposited black carbon, and other perturbations, with an aim to
improve the synthesis of multisensor aerosol observations from space;
and

4\. **Chemical processes** with focus on ozone and aerosols, including
particular attention to the chemistry of halogen and hydrogen oxide
radicals and to stratosphere-troposphere exchange.

Plans for the ARCTAS campaign include two deployments: a spring
(March-April 2008) and a summer (June-July 2008) deployment of the DC-8,
with exact timing and bases of operations still being deliberated based
on science and other considerations. ROSES 2007 A.13 and the White Paper
describe possible participation by two other aircraft, called the J-31
and B-200 in A.13 and the smaller profiling aircraft and constant-level,
remote-sensing aircraft in the White Paper. Since the release of those
documents, plans have evolved, and the NASA Wallops P-3 is now planned
to play the roles originally ascribed to the J-31/smaller profiling
aircraft. Per ROSES 2007 A.13, the workforce plan in this proposal
assumes that each deployment is 4 weeks long.

The spring deployment will be based at North American and/or European
arctic/subarctic sites. An attractive possibility for the spring
deployment mentioned by the ARCTAS White Paper would be to base the DC-8
for 1-2 weeks in Kiruna, Sweden followed by 1-2 weeks in Fairbanks,
Alaska, with the smaller platforms based in Fairbanks throughout the
Spring deployment. Also being considered for the P-3 in spring is using
Thule Air Force Base in Greenland en route to or from Fairbanks, as a
means of gaining better access to arctic haze. The summer deployment
will be based at North American arctic/subarctic sites. Edmonton
(Alberta), Cold Lake (Alberta), Winnipeg (Manitoba), and Grand Forks
(North Dakota) are potential sites being discussed at this writing.

Table 1 lists priority measurements for the smaller aircraft in ARCTAS.
Although the White Paper tables do not specify the division of
measurements among the smaller platforms, recent

discussions indicate that the smaller profiling aircraft (P-3) will
carry instruments to measure optical depth spectra, radiative flux
spectra, radiance spectra, and possibly in situ aerosol properties (see
Table 2), and that the constant-level aircraft will make lidar and
polarized radiance measurements (with the possibility of additional
polarized radiance measurements on the P-3). Other instruments likely to
be proposed for the P-3 in ARCTAS include broadband flux radiometers, a
thermal IR scanner, and a rainbow camera.

As noted in the ARCTAS White Paper, measurements on the smaller aircraft
add considerable value to those planned for the DC-8. Aircraft
measurements of radiant flux and radiance can characterize surface
albedo and the bidirectional reflectance distribution function (BRDF) to
improve satellite aerosol retrievals. Low-altitude mapping of UV/Vis/NIR
surface albedo and (polarized) BRDF during ARCTAS will also provide
unique information that can provide larger-scale context for surface
measurements of ice and snow albedo and other properties, including
black carbon concentration. Both surface-based and coordinated airborne
measurements are needed to gain best understanding, because variables
other than soot, such as snow grain size and melting state, also affect
snow and ice albedo. One goal of the combined measurements is to
evaluate the potential of satellite measurements to map black carbon
deposition and the resulting albedo effect in the Arctic. Because of the
multiple factors that affect snow and ice albedo, achieving such maps
from space is extremely challenging.

ARCTAS will also attempt to coordinate with a DOE aircraft mission in
April 2008 over Alaska focused on aerosol-cloud radiative interactions
(White Paper Table1).

Aerosol observations from CALIPSO, MODIS, MISR, and OMI, together with
aircraft in situ characterization of aerosol plumes, will greatly help
to constrain source-receptor relationships. Aircraft measurements will
also provide information on the evolving mixing state of the black
carbon aerosol prior to deposition, and how this mixing state varies
with source type and source region.

Figure 2 shows nominal flight patterns for the smaller profiling
aircraft, and Figure 3 shows nominal flight patterns for coordinated
flights by the smaller aircraft and the DC-8. The key flight patterns
shown in Figure 2 are:

**1. Survey vertical profile.** Often flown when first arriving at a
measurement site, this spiral pattern provides profiles of aerosol
optical depth (AOD), aerosol extinction, column water vapor (CWV), water
vapor density, and aerosol in situ measurements (Table 2). 5-min
transects at profile top and bottom provide radiant flux and radiance
measurements describing the surface and the atmospheric column.

**2. Minimum-altitude transect.** Usually flown at or near satellite
overpass time, this transect provides AOD and CWV measurements of the
full column viewed by the satellite while radiometers measure the
surface. Long transects can measure gradients and other spatial
structure in the satellite scene.

**3. Stepped profile** (also called "parking garage"). This includes
horizontal legs and linking ramps. The horizontal legs permit
measurements of radiative fluxes and radiances describing selected
aerosol layers, at altitudes chosen on the basis of the survey vertical
profile.

**3\'. Stepped profile orbit.** This provides radiance measurements to
characterize surfaces and aerosols.

**4. Above-cloud transect.** This provides measurements of AOD spectra,
CWV, and in situ aerosol properties above cloud, plus radiometric
measurements of cloud properties.

**4\'. Above-cloud orbit.** This provides radiance measurements to
characterize clouds.

**5. Linkages and intercomparisons with other POLARCAT platforms.** This
involves spirals and transects within lidar curtains of other aircraft,
and fly-bys of surface sites (including AERONET sun/sky radiometers).

## Other Polar Research Planned During ARCTAS 

### Ground Measurements of Soot Effects on Snow Albedo

Drs. Steve Warren, Tom Grenfell, and Antony Clarke are currently funded
to make measurements of snow and ice albedo as affected by
simultaneously measured soot at various locations in the arctic. Their
measurements began in March 2007 and will continue into Spring 2008.
Current plans are to make measurements near Barrow, Alaska during the
ACRTAS Spring 2008 deployment. We have discussed with them making
coordinated aircraft measurements of surface albedo and reflectance, as
well as other aircraft measurements over their measurements. The
purposes of the coordinated aircraft measurements would be to provide
larger-area context for the ground measurements, compare air and ground
measurements, and provide a link to satellite measurements in the area.

### Ground-based Remote Sensing Measurements

Many previous experiments have demonstrated the value of having
ground-based lidar and sun-sky photometer measurements in the vicinity
of aircraft measurements. Among other benefits, they provide a
longer-term record of aerosol vertical profiles, AODs, and other
retrieved properties that set the vertical and temporal context of the
aircraft measurements. We have discussed with Drs. Brent Holben of
AERONET, Judd Welton of MPLNET, Glenn Shaw of the University of Alaska,
and others the potential availability of lidar and sun-sky photometer
measurements in range of the P-3 bases in ARCTAS. So far we have learned
of lidar and sun-sky photometer measurements by DOE at their North Slope
of Alaska site, lidar measurements by the University of Alaska at
Fairbanks and possibly Barrow, and possibly other sun-sky photometer
measurements within P-3 range. We will continue contacts to be aware of
all possible coordinating measurements as we move into intensive ARCTAS
planning.

## Detailed Description of Proposed Work

The following subsections provide more specifics on the proposed
coordination services. These will draw on our previous experience in
coordinating aircraft, satellite, and surface-based measurements in
INTEX-B (J-31, King Air, C-130, DC-8), INTEX-A (J-31, DC-8, NOAA P-3),
ACE-Asia (C-130, Twin Otter, ship), SAFARI 2000 (CV-580, ER-2, surface
sites), ACE-2 (Pelican aircraft, surface sites), and TARFOX (C-131,
Pelican, C-130, ER-2).

### Develop an integrated set of ARCTAS scientific objectives for all instruments on the P-3

We will work with all P-3 instrument PIs to collect their ARCTAS
scientific objectives and integrate them into a scientific whole. This
will be similar to the role we played most recently in INTEX-B for the
J-31 and previously for other aircraft in the experiments mentioned
above.

### Represent instrument PIs in determining the best deployment bases & schedule to achieve those scientific objectives

Choice of deployment bases and schedules is already well underway, but
to the extent that refinements remain (e.g., regarding "suitcase"
overnight deployments to other bases depending on atmospheric and other
conditions), we will offer our services as a focal point regarding PI
preferences.

### Develop an instrument-integration and test flight schedule in concert with instrument PIs and the P-3 operator (NASA Wallops)

P-3 integration planning and scheduling is also underway, but to the
extent that integration and test-flight scheduling remains to be
finalized, we will offer our services as a focal point regarding PI
preferences.

### Coordinate development of generic/modular flight plans before deployment & of actual flight plans during deployment

Figure 4 shows examples of the modular flight plans developed by Dr.
Redemann before the INTEX-B J-31 deployment by working with J-31 and
King Air instrument PIs, as well as with pilots and Air Traffic Control
personnel to determine what is safe and otherwise feasible. These proved
very useful in focusing thinking before the deployment and helped
facilitate the development of actual flight plans on tight schedules in
the field. We propose to provide a similar service for the P-3 in
ARCTAS. During the ARCTAS P-3 deployments we will coordinate the
development of flight plans with pilots and ARCTAS scientists, taking
into account satellite overpasses, weather forecasts (including cloud
forecasts), model predictions of aerosols and other atmospheric
constituents, plans of other aircraft and surface sensors, and flight
hours already devoted to specific objectives relative to the plan
described in Section 1.5.5.

### Develop a plan that allocates flight hours to scientific objectives by priority

In ACE-Asia, working with C-130 instrument PIs, we participated in the
development of a matrix of measurement priorities based on instrument
scientific objectives and overall project goals. This proved useful in
allocating flight hours while allowing flexibility to adjust to weather,
take advantage of targets of opportunity (aerosol, cloud, and surface)
and address multiple objectives on a given flight. We propose to work
with ARCTAS PIs to develop an analogous plan.

### Provide maps of satellite tracks and areas of sunglint and desired elevation angles

Figure 5 shows examples of the maps of satellite tracks and areas of
sunglint and desired elevation angles developed by Dr. Redemann and Ms.
Zhang before and during the INTEX-B J-31 deployment. These maps were
essential to flight planning in the field. We propose to provide
analogous maps for appropriate satellites (including CALIPSO ground
tracks) and the ARCTAS P-3 deployment areas, in time for flight planning
schedules.

### Serve as P-3 Flight Scientist and/or delegate this flight by flight

In ACE-Asia Dr. Russell was assigned responsibility as Mission Scientist
(i.e., Flight Scientist) on 11 C-130 flights. He performed these duties
onboard for 9 flights and delegated them to two other scientists on the
remaining two flights. In other campaigns (e.g., TARFOX, ACE-2, INTEX-B)
he performed his coordination duties on the ground, while others served
as Flight Scientist for particular aircraft. As J-31 Lead PI in INTEX-B,
he designated the Flight Scientist before each flight.

Dr. Redemann has served as Flight Scientist for the J-31 in INTEX-B and
as Mission Scientist for the Twin Otter in EVE.

Depending on the situation in the field and prior agreements with NASA
HQ program managers, Dr. Russell will serve as P-3 Flight Scientist for
some flights and delegate this responsibility for other flights. If the
P-3 carries in situ instruments, Flight Scientist responsibilities will
be appropriately shared with one or more in situ instrument scientists.

### Submit a flight report for each flight served as flight scientist

Reports will be submitted on project schedules, generally within one day
of the subject flight.

### Coordinate P-3 flights with other ARCTAS A/C, ground sites, and satellites

This coordination will focus on carrying out the goals of the ARCTAS
themes, drawing on experience from the previous experiments mentioned
above. This experience includes dealing with the complexity of
coordinating multiple aircraft at different, changing altitudes in the
tight time constraints of a satellite overpass, all subject to
maintaining flight safety.

### Coordinate post-deployment data workshops, archival, publications, etc

This responsibility will be shared with other ARCTAS coordinators,
focusing on the P-3. It will be analogous to the role played by Dr.
Russell for the J-31 in INTEX-A and -B, and for other aircraft in
previous experiments.

### Lead & participate in integrated analyses, presentations, & publications

On this task Drs. Russell and Redemann will apply their scientific
backgrounds to bringing together ARCTAS data from several sources
(including several airborne instruments, satellites, and ground-based
instruments) to address ARCTAS goals.

## Management Plan

### Roles of PI and Co-I

Dr. Philip B. Russell will be Principal Investigator. He will be
responsible for the overall scientific direction, project management,
administration, and communications with NASA HQ. He will be responsible
for completing the work on time and within budget. Dr. Jens Redemann
will be Co-Investigator. A primary role will be developing the type of
generic, pre-deployment flight plans he developed in INTEX-B (see
Section 1.5.4 and Figure 4).

### Roles of Collaborators

Dr. Antony Clarke of U. Hawaii will collaborate on several aspects of
the P-3 instrumentation and mission deployment.  His expertise on
in-situ measurements will be used to help refine and optimize any
in-situ instrumentation issues that need to be considered for
installation and operational capabilities.  These might include sampling
ports, inlet choices, instrument locations, coordinated sampling
capabilities, ancillary measurements etc.  These may also involve issues
related to optimizing in-situ and remote sensing coordinated objectives.

   Assuming that an in-situ measurement component is significantly
integrated onto the P-3, it is also anticipated that Dr. Clarke will
actively work on formulating flight plans and individual mission
objectives that maximize the benefit of co-located in-situ and remote
sensing capabilities.  Both Dr. Russell and Dr. Clarke have experience
working together on such objectives in the past (ACE-Asia, INTEX-A,
INTEX-B) and a shared interest in coordinating their activities with
satellite objectives.

Dr. Ralph Kahn of Jet Propulsion Lab has proposed separately, as MISR
Aerosol Scientist, to participate directly in field operations during
ARCTAS, representing the scientific objectives of the Multi-angle
Imaging SpectroRadiometer (MISR) instrument aboard the Terra Satellite,
and possibly other satellite instruments. As with previous campaigns
(see Kahn letter of support in Section 6.2), he will participate in
pre-campaign experiment design efforts and climatology assessments, will
be involved in day-to-day flight planning, including meteorological
assessments and rapid science analysis in support of field operations,
and will lead the MISR data analysis component of satellite aerosol
retrieval validation, regional mapping of aerosol amount and type,
comparisons with aerosol transport models, and aerosol-climate as well
as air quality assessments. Due to the frequent cloud cover and other
challenging environmental factors for this deployment, achieving his
experimental goals for ARCTAS will require close and effective
coordination with the sub-orbital platforms, which would be provided by
the program proposed here.
