## Introduction to MODIS design, calibration and processing

- Modified from PPT presented by Ewa Ainsworth (SAIC/NASA-GSFC)

## MODIS design and calibration

**SD** – Solar Diffuser, primary source for the absolute radiometric calibration of VIS and NIR bands
**SDSM** – Solar Diffuser Stability Monitor, alternately views the Sun through an attenuation screen and the light diffusely reflected from the SD and ratios the obtained radiances
**SRCA** – Spectroradiometric Calibration Assembly
**SWIR** – short-wave IR
**MWIR** – medium-wave IR
**LWIR** – long-wave IR
**FPA** – Focal Plane Assembly

**Notes:**
SD – Solar Diffuser, primary source for the absolute radiometric calibration of VIS and NIR bands 
SDSM – Solar Diffuser Stability Monitor, alternately views the Sun through an attenuation screen and the light diffusely reflected from the SD and ratios the obtained radiances
SRCA – Spectroradiometric Calibration Assembly
SWIR – short-wave IR
MWIR – medium-wave IR
LWIR – long-wave IR
FPA – Focal Plane Assembly 

## Sensor characterization and calibration concerns

- Solar Diffuser characterization
- Bi-directional Reflectance Factor (BRF) impact on calibration
- Earth shine effect – sunlight reflecting off the Earth and onto the diffuser and adding to the solar irradiance
- Attenuation screen characterization through vignetting function
- SDSM uncertainty in monitoring SD reflectance changes

- Mirror degradation, Response Versus Scan-angle (RVS), two mirror sides
- Detector calibration changes
- Polarization sensitivity
- In-band and out-of-band response
- Instrument and focal plane temperature effects
- Electronic cross-talk
- Stray-light contamination
- Solar Diffuser stability

- Stray-light contamination
- Photons in the optical path from Earth coming from bright sources, i.e. clouds, land, and sun glitter (characterized by point spread function)

## MODIS calibration stages

**Direct calibration**
**Pre-launch** – sensor is calibrated in a laboratory (thermal vacuum)
**On-orbit** – regular solar, deep-space, and lunar observations track changes in sensor response (possible additional on-board calibrators)
**Absolute radiometric accuracy **
- reflective solar bands (0.41 – 2.1m): ±2% in reflectance and ±5% in radiance
- thermal emissive bands (3.7 – 14.4m): ±1% for most bands
**Vicarious calibration **– uses sources independent of the primary direct calibration – *in situ* measurements

## AMS-02 Risk Management Process

- Chris Tutt
- Rebaselining Review Outbrief
- 15 July 2004

## Introduction

- As part of rebaselining effort, LMSO has initiated a formal risk tracking system.
- Risk database still being populated.
- Risk matrix will be available on AMS-02 project web page.
- Risk summary reports will be presented regularly at AMS-02 team meetings and quarterly TIMs.

## AMS IRMA 

- AMS risk management tool based on ISS IRMA.
- Risks rated by likelihood and consequence on a scale of 1-5.
- Risks plotted on 5x5 grid and ranked by color.
- AMS consequence scaling adjusted from ISS IRMA to better suit project needs.

## AMS Consequence Categories

- Risk consequences divided into four categories:
- Cost
- Schedule
- Safety
- Mission Success
- Within each category, consequences scaled to five levels:
- Minimal Impact
- Moderate Impact
- Major Impact
- Mission in Jeopardy
- Project Killer

## Proposed Consequence Levels

## Current Tracked Risks

- 22 open risks currently in the database.
- 5 red
- 12 yellow
- 5 green
- Existing risks primarily reflect PIH and integration issues.
- LMSO will work with AMS collaboration to add experiment-related risks where appropriate.

## Current Top AMS-02 Risks

- Five risks currently in red zone:
- #1113 – RTF Related Launch Slips (Schedule 4)
- #1114 – SFHe Tank Manufacturing (Cost 4)
- #1119 – Warm Helium Valve Design (Schedule 4)
- #1122 – SSRMS/SPDM Magnetic Field Issues (Cost 4)
- #1125 – AMS as Attached Payload Pathfinder (Cost/Schedule 4)
- Two risks currently with level 5 consequences
- #1115 – Nonlinear Support Strap Verification (Cost/Schedule 5)
- # 1127 – Payload Bay Venting (Cost 5)

## Forward Work

- Work with AMS collaboration to properly categorize existing risks and identify new risks.
- Work with NASA/JSC to ensure that risk database has appropriate level of detail.
- Implement mitigation plans for significant risks.

## Universality in the photophysics of single-walled carbon nanotubes and -conjugated polymersSumit Mazumdar, University of Arizona, DMR-0406604

-     Single-walled carbon nanotubes (SWCNTs) and -conjugated polymers are both quasi-1D -electron  systems.   Ultrafast spectroscopy reveals two distinct photoinduced absorption, PA1 and PA2, in both classes of materials.
-     Our theoretical work demonstrates that the “essential states”  model  of  optical  non-linearity,  developed  originally  for  the  -conjugated polymers,  applies  also  to SWCNTs.   PA1 is from the lowest optical exciton Ex1 to a single dominant m1Ag two-photon exciton in zigzag NTs, and to a narrow band of m“1Ag” excitons in chiral NTs.

## Universality in the photophysics of single-walled carbon nanotubes and -conjugated polymers Sumit Mazumdar, University of Arizona, DMR-0406604

-   One graduate student and one post-doctoral fellow were trained under the program.
-   The group collaborates with the experimental group of Professor Z.V. Vardeny from the University of Utah on the photophysics of carbon nanotubes and π-conjugated polymers. Graduate students from the experimental group have benefited from the mentoring by the PI.
-   Aspects of our research, many-electron effects on low dimensional systems, in particular organic materials, have been incorporated in a new graduate course on advanced topics on condensed matter theory at the University of Arizona.

## Nano-Scale Atomic Structure by Neutron ScatteringT. Egami: University of Tennessee at Knoxville, DMR 0404781

**Nano-Scale Atomic Structure by Neutron Scattering****T. Egami: University of Tennessee at Knoxville, DMR 0404781**

- The conventional method of structural characterization by crystallography fails when the object is smaller than a few nm, since the diffraction peaks (Bragg peaks) become too wide. On the other hand the local probes such as x-ray absorption fine structure (XAFS) and NMR can see only the closest neighbors within 0.5 nm. This leaves a gap in the nano-scale structural characterization for 0.5 – 3 nm.
- The method of atomic pair-density function (PDF) with pulsed neutron scattering can fill this gap. PDF describes the distribution of atomic distances in the materials. Using the NPDF spectrometer at the Los Alamos National Lab. (recently upgraded by us with NSF DMR00-76488) we determined the PDF of superconducting cuprates, La2-xSrxCuO4 as a function of *x* (0 – 0.3) and *r* (0 – 5 nm) at 10 K.
- The results shown here demonstrate rich, non-trivial composition dependence that reveals important local variation which is an intrinsic part of the high-temperature superconductivity phenomenon.

*r* = 10 ~ 20 Å

## Reaching Beyond T. Egami: University of Tennessee at Knoxville

- Radio Interview
- On Aug. 15, my voice traveled the air, as a part of a program from WUOT, a public radio station at Knoxville. The 30 min. program was on the transition of Oak Ridge from the site where isotopic uranium for an atomic bomb dropped in Japan was produced during the war, to the present research center focusing on energy, transportation and environment. I was interviewed as a Japanese-American scientist who now works in the re-born Oak Ridge. I pointed out that the atomic energy is a tool, just like a knife that can either kill people, create an object of art, or used in cooking, and it is up to us to use it right. I also spoke about how international border has disappeared in science, how exciting to be a part of the cutting edge research using the best neutron facilities in the world.
- Special Class
- As a part of the International Materials Institute activities I taught in a special graduate class on the fundamental theory of glasses. The class was open to researchers including those at Oak Ridge National Lab.
- Improving Public Software
- An important outcome of our research on the pulsed neutron scattering was a discovery that the current method of data processing for the atomic pair-density function (PDF) is not sufficiently accurate, and we can do much better. We are in the process of implementing our discovery into the public software so that the results of our research can be shared by wide general users of neutron scattering.

**A Comprehensive 3D Digital Atlas Database of the C57BL/6J Mouse Brain Developed Based on **
**Magnetic Resonance Microscopy Images:**** **
- AMRIS investigators published more than 30 peer reviewed papers in 2005, including 2 additional cover articles and a feature in *Science*. The use of transgenic mice has revolutionized biomedical research and genetics, and numerous genetic diseases can be studied and better understood with a “mouse model” of the disease. Before the effects of the mutations can be fully understood, however, a bench-mark study of a normal mouse is needed.
**Drs.

## AutoWord Demise(Modified)by Steve Lloyd

## AutoWord

- AutoWord (formerly known as Autoclause)
- Released in 1995
- Primary Solicitation/Contract Generation tool for 13 years
- Temporary solution until HQ delivered an agency-wide tool
- Has not been updated since the Part 45 changes last summer
- Labor intensive to update templates

## The CMM Experience

- Solicitation/Contract Drafting has not been the most pleasant experience for those that tried last year

**Clauses out of Sequence!**

## The CMM Experience Cont’d

## PRISM

- Check-list based system, Section by Section
- Limited “local” prescriptions with a 2-clicks approach to get to the full FAR/NFS prescription
- Fixed “clauses out of sequence” issue in November
- Changes/edits outside system vs. in-system
- Remember - Just because it looks different doesn’t mean it’s wrong

## PRISM Cont’d

- Generated *RTF file Differences
- No Table of Contents
- No Headers/Footers (No Page #’s, No Solicitation  #)
- No section breaks between UCF sections
- By reference clauses are all currently numbered (e.g. I.1 thru I.67)
- Unique Clauses – currently “ugly” such as  SECTION # CONTRACT SPECIFIC ADDITIONAL CLAUSE #

## The Plan

- Phase-out Autoword over the next few months
- Revamp GSFC Sections L&M into a few word files that can be merged into the PRISM generated document
- Local GSFC Clauses
- 12 are currently in CMM
- 17 are now UCF Completion Statements in CMM
- Remaining are awaiting NFS changes or may need to be added back to the local database
- Start mini-training sessions over February and March (likely 2 hours)
