# 2 INTRODUCTION

One of the key questions in atmospheric science is "what factors control
the concentration and distribution of tropospheric ozone (O~3~)?"

Tropospheric ozone is important for three reasons:

1.  It is the principal component of photochemical smog. Ozone near the
    surface (in the so-called "boundary layer") can be toxic to humans,
    plants and animals.

2.  In the free troposphere (roughly 2-10 km above the surface), ozone
    reacts with water vapor in the presence of sunlight to form the
    hydroxyl radical (OH). OH, in turn, is the primary cleansing agent
    of the atmosphere, removing carbon monoxide (also a toxic chemical
    almost totally generated by industrial activity) and other harmful
    chemicals such as the new hydrogenated fluorocarbons (used as CFC
    substitutes) from the atmosphere. In the presence of nitrogen
    oxides, OH is also recycled back to O3, thus sustaining its
    concentration.

3.  In the upper troposphere (just below the boundary with the
    stratosphere), ozone is a significant greenhouse gas.

Many of the chemicals involved in the formation and destruction of
tropospheric ozone are quite short-lived (seconds to a few months).
Their vertical and horizontal distributions in the troposphere are
therefore very non-uniform and difficult to monitor from ground stations
or the occasional balloon or aircraft campaign. Furthermore, there are
only a limited number of such ground stations in the world,
preponderantly in the northern hemisphere and all, of course, on land.
The three-quarters of the Earth's surface that is ocean is essentially
unmeasured.

Thus there is a clear-cut role for space-based observations of the lower
atmosphere - it is the cheapest and most effective way of getting a
global picture of what may loosely be termed "atmospheric pollution".
Note that the problem of tropospheric ozone is quite different from the
better-known stratospheric ozone problem. Tropospheric ozone appears to
be *increasing* on a global scale whereas, of course, stratospheric
ozone is *decreasing* with a concomitant increase in solar ultraviolet
radiation reaching the surface, increasing the risks of skin cancer.
Further note that a) there is roughly 10 times the amount of ozone in
the stratosphere as in the troposphere and b) gas exchange between the
two is slow and sporadic (indeed, the mechanisms for exchange are only
poorly understood).

In order, then, to investigate tropospheric ozone and the factors that
control its formation and destruction, it is necessary not only to
measure ozone itself but also to determine the physical and chemical
environment of the Earth's lower atmosphere. This is the mission for
which the TES experiment was devised.

# 3 PROJECT DESCRIPTION

The TES experiment has two parts - the TES instrument itself and a
ground data system. The satellite instrument is an imaging infrared
Fourier Transform Spectrometer (FTS). TES has both nadir and
limb-viewing capability and covers the spectral range 650 - 3050 cm^-1^
at either 0.08 cm^-1^ or 0.02 cm^-1^ spectral sample spacing[^1].

TES has 4 co-aligned detector arrays of 1x16 elements (pixels), each
array optimized for a different spectral region. Each pixel
Instantaneous Field-of-View (IFOV) is 0.075 mrad high by 0.75 mrad wide.
At the limb, this corresponds to about 2.3 km altitude by 23 km parallel
to the horizon. In the nadir, the footprint corresponds to 0.5 x 5 km.
Each of the detector arrays is equipped with a filter wheel containing
filters 200 - 300 cm^-1^ wide both to reduce instrumental background
noise and to permit interferogram sampling at relatively coarse
intervals in order to reduce the data rate. A complete description of
the TES experiment can be found in Reference 1.

TES has two basic science operating modes: Global Surveys and Special
Observations. For Global Surveys, continuous sequences of a space view
and a blackbody view calibration pair, two nadir views and 3 limb views
are acquired. Calibrations and nadir views require 4 seconds each, limb
views 16 seconds. Adding in the times needed for accelerating and
decelerating the moving element of the FTS, each sequence requires 81.9
seconds to accomplish. 72 sequences are acquired on each orbit,
triggered by passage of the orbital southern apex, and an entire survey
requires 16 orbits (about 26 hours). Each survey is preceded and
followed by 2 orbits of pure space and blackbody views for calibration
purposes. The Aura orbit has a 16-day repeat period so Global Surveys
are made on a "1 day on, 1 day off" cycle, although the "off" time is
significantly shorter than the "on" time. Triggering from the southern
apex ensures that the same locations are observed repeatedly for the
lifetime of the mission. Global Surveys are the source of TES Standard
Products which will be archived at the NASA Langley DAAC and are
mandated by our Level 1 Requirements.

Special (Research) Observations fall into two general categories. The
first category is targeted nadir observations of specific locations such
as volcanoes or biomass burning. Such observations are made for as long
as the target is within ±45^o^ of the nadir direction (up to 210
seconds). The second category is to make transect observations: up to
about 950 km long down-looking and essentially indefinitely at the limb.
In every case, such observations are accompanied by appropriate
calibration sequences. Special Observations are made only during the 9
or 10 orbit gaps in the Global Surveys. These results will be archived
at JPL.

The Ground Data System also has two parts. Standard Products are
produced at the Science Investigator Processing System (SIPS), located
at the Raytheon facility in Pasadena. Except for the conversion of the
raw data stream back to interferograms, all Special Products are
produced at the Science Computing Facility (SCF) at JPL. The SCF also
supports all algorithm development and quality control.

# 4 OPERATIONS PLANNING

Operations Planning is, primarily, the joint responsibility of the
Science Team and the Flight Operations Team. These teams will meet at
least once a week (daily during the early mission) to a) review the most
recent activities and b) develop a rolling plan for the following month.

Since Global Surveys are the routine observations made by TES, they are
conducted according to a pre-planned schedule (see Section 8, below).
Only in the event of scheduled spacecraft maneuvers etc. will the
intervention of the planning teams be required. Thus most of the
planning will be focused on the Special Observations. Special
Observations are described in detail in Section 9.

Instrument control is *via* special flight software subroutines called
*macros*. The Global Survey macros are stored on board permanently (but
are, nevertheless, modifiable). All others are sent to the spacecraft by
weekly command uploads. Many macros would be quite similar if there was
one for each possible observation so, to keep the number reasonably
small, each is accompanied by a Macro Parameter Table (MPT) which is
simply populated with the needed input data (for example, latitude,
longitude and height of observation, filter settings, gain settings,
etc.).

# 5 MISSION MODES

Figure 1 shows the TES detector arrays projected to the nadir and to the
limb (which is some 3000 km behind the spacecraft) and Figure 2 shows
the observation geometries available to TES.

Figure 3 shows a pictorial timeline of the Global Survey mode.

Figure 4 shows a schematic of the Transect Mode (used primarily for
regional pollution studies and validation campaigns). The Staring Mode
(used for volcano monitoring, biomass burning observations and localized
validations) is similar to the Transect Mode but with all the successive
steps collapsed to a single location.

# 6 COMMISSIONING PLAN (L -\> L+3 months)

The first 90 days after launch are termed the *commissioning phase*. The
major events happening during this time are the opening of the Earth
shade, outgassing of the inevitable water vapor trapped in the thermal
blankets[^2], detector cool-down and thermal tuning of the optical bench
temperature to achieve optimal alignment (assessed by observation of the
internal 340K black body). Table I shows an overview. A more detailed
commissioning timeline can found in Appendix A. Most of the data
generated during this time fall into the category of Special
Observations (i.e., are processed beyond L1A at the SCF).

  ------------------------- ---------------------------------------------

Notes to Table I:

1\) For the first year, TES will concentrate on retrievals in cloud-free
areas to facilitate comparisons to ozonesondes, aircraft and ground
based campaigns, radiance comparisons with AIRS, and comparisons to
chemical transport models such as GEOS-CHEM and MOZART.

2\) One full Global Survey (the "golden day") will be used for detailed
verification of end-to-end processing.

3\) Decontamination cycles will be done when signal loss indicates ice
build-up on the detectors

4.  L1B spectral radiances and L2 retrievals will be made available to
    the validation teams through the Aura Validation Data Center (AVDC)
    at the Goddard SFC.

# 7 EARLY MISSION PLAN (L+3 -\> L+9 months)

This will be a transition phase wherein we closely monitor the
instrument alignment; contamination and translator usage. This will also
be a period when significant early validation is done; more-or-less
routine Global Surveys are performed and data processing at the SIPS
becomes routine. Note that all SIPS-processed data will be archived at
the LaRC DAAC.

# 8 LATE MISSION PLAN (L+9 -\> mission end)

For the rest of the mission, we shall perform Global Surveys and Special
Observations on the schedule shown in Table II.

Notes to Table II:

1\) Except for emergencies, Global Surveys will ***never*** be
interrupted (e.g., by Special Observations).

2\) By the same token, if some pre-planned event (e.g., a spacecraft
maneuver or orbit adjustment) would interrupt a Global Survey, the
survey will be skipped in its entirety. A "partial" Global Survey is an
oxymoron. Furthermore, this decision forms part of the ICS translator
management plan.

# 9 SPECIAL OBSERVATIONS

## 9.1 Special Tests and Calibrations

TES has a variety of test and calibration modes. Some involve the
acquisition of interferograms, many do not. Among the latter are
performance tests of both the ICS and the PCS. The ICS performance test
is of particular importance because the translator mechanism is believed
to have a limited lifetime[^3] and both the power consumed by the drive
motor and the total distance traveled are important metrics of the
health of this sub-system.

Tests that generate interferograms include radiometric assessment of the
instrument. Both cold space and 340 K on-board radiometric calibration
source (OBRCS) data are acquired in this process. The results have
numerous uses:

1)  Changes in the spectral character in certain specific filters are
    indicators of ice build-up on the detectors.

2)  Changes in interferogram phase and wavelength-dependent amplitude
    changes are indicators of beamsplitter alignment drift.

3)  Noise Equivalent Spectral Radiance (NESR) is an important metric for
    overall instrument health and performance. NESR is also routinely
    derived from all calibration measurements.

Another important measurement is the co-boresight test which uses the
on-board spatial calibration source (OBRCS).

All of these tests (plus many more) are performed regularly for the life
of the mission.

## 9.2 Staring Mode Observations

Staring Mode observations are the simplest to understand. The MPT is
simply loaded with a latitude and longitude and TES points to that
location for as long as the nadir angle is less than 45^o^. Figure 5
shows the available stare time as a function of the nadir angle of the
target at closest approach. The only real complication comes about when
the target is at high altitude (many volcanoes, for example). Under
those circumstances parallax becomes a non-negligible effect and the MPT
must contain a slightly different latitude and longitude for each scan
(usually short scans). It should also be noted that if the target does
not lie in the ground track, the PCS will require a varying roll angle.
The footprint rotates by the same amount and, since it is changing,
implies that (in general) scan averaging will not be possible.

![](media/image6.wmf)

### 9.2.1 Volcanoes

The volcanology community has identified 10 volcanoes that they would be
interested in having TES monitor. Their common factor is that they emit
copious amounts of gas (chiefly sulfur dioxide, but many other ones as
well). It is believed that the exact mix of gases is an eruption
predictor (Reference 2).

**Table III: Candidate Volcanoes to be Monitored**

  White Island            New Zealand        -37.520        177.180
  ----------------------- ------------------ -------------- ---------------

Note to Table III: Depending on the specific orbits chosen for the
Global Surveys, some of these volcanoes may not be accessible (they must
be less than \~500 km from the closest ground track).

### 9.2.2 Biomass Burning & Major Industrial Accidents

Biomass burning, especially in the tropics in the September-October time
frame, is a major source of atmospheric pollutants. The regions where
this occurs are well known, so we can plan staring observations of those
fires. Other major brush and forest fires occur frequently but in many
different locations. Provided that we can get timely information on
their locations, most can be observed with a delay of 48 hours or less.
Major fires can, of course, burn for many days, even weeks. We already
have experience in analyzing remotely-sensed data from wildfires
(Reference 3).

Similarly, major industrial accidents (e.g., Chernobyl, Bhopal) can be
targeted if we receive timely information. It must, however, be
emphasized that TES is not intended to be part of a disaster management
program -- our spatial resolution is designed for regional, not local,
measurements.

### 9.2.3 Validation Sites

There are a number of permanently-instrumented (some heavily) validation
sites around the world. The ones most useful to TES are likely to be
those participating in the DoE Atmospheric Radiation Measurements (ARM,
Table IV) program[^4]. All standard meteorological measurements are made
continuously, together with sondes and down-welling infrared radiances.

The NASA Network for the Detection of Stratospheric Change (NDSC, Table
V), although (as its name suggests) primarily aimed at the upper
atmosphere, also makes useful tropospheric measurements.

We are also in the process of identifying other locations that can be
used for up-welling radiance measurements (Table VI), some of which will
also be useful for calibrating the Pointing Control System (PCS).

[]{#__RefHeading___Toc69006581 .anchor}*9.3 Transect Mode Observations*

Transects are necessarily made in the ground track. Because of the field
rotation alluded to earlier it is not possible to "stack" off-track
observations satisfactorily. However, since transects are intended for
observation of regional phenomena and to support aircraft validation
campaigns where the aeroplane simply needs to under-fly the ground
track, this is not a limitation.

### 9.3.1 Down-looking Transects

Down-looking transects (the most common variety) use short scans.
However, because each scan is individually targeted, it is possible to
make multiple scans at each location. The price paid is in the overall
length of the transect because of the limitation to +/- 45^o^ nadir
angle (Table VII).

**Table VII: Maximum Transect Lengths**

  ---------------------------------- ------------------------------------
  **No. of scans/step**              **Maximum Transect Length (km)**

  1                                  949

  2                                  349

  3                                  220

  4                                  132
  ---------------------------------- ------------------------------------

Transects are created by pre-calculating the latitude and longitude of
every step (a straightforward process) and loading the data into the
MPT.

### 9.3.2 Limb Transects

Limb transects are primarily used for instrument intercomparisons. For
example, the HiRDLS instrument on Aura covers the same spectral range as
TES and can look backwards along exactly the same line-of-sight as TES.
The difference is that HiRDLS is a broad-band radiometer with very good
vertical resolution (\~ 1 km). TES, on the other hand, has poorer
vertical resolution (2.3 km) but much better spectral resolution. The
combination of data from the two instruments should result in a superior
joint product.

Limb transects are created simply by putting TES into its limb mode and
making repetitive long scans. In principle, there is no limit to the
length of such a transect.

*However, long scans are costly in terms of translator life, so the mode
is to be used sparingly.*

[^1]: The term "spectral sample spacing" is preferred over the more
    usual "spectral resolution" because it more accurately reflects the
    character of the FTS output. Furthermore, spectral resolution
    depends on whatever apodization may be purposefully or inadvertently
    applied to the data.

[^2]: ^2^ Signal loss due to absorption by ice on the detectors was a
    significant effect during thermal vac testing

[^3]: ^3^ The life test unit failed after the equivalent of about 2
    years of normal operations.

[^4]: ^4^ Two TES co-investigators are also active members of the ARM
    program, so we have ready access to ARM data.
