## Terra Status

- All instruments acquiring science data
- MODIS A-side formatter timeouts increasing (~30M/day). Plans are being made for cross strapping the instrument.
- MOPITT still working on half of its channels.
- Terra performing a series of inclination adjust maneuvers to establish 10:30am _+_ 5 min. equator crossing.  Went in to safehold following last inclination adjust maneuver in March.   6th and final maneuver postponed until September to accommodate implementation of the Lockheed recommendations regarding spacecraft procedures.

## Terra Status

- SWIR crosstalk problem on ASTER is encouraging ASTER to “accept” lunar look maneuver.
- Recompetition – RFP concept discussed last team meeting has changed to NRA.  Joint call for Maintenance and Science.  Current NRA prepared by Jim Dodge is being reviewed by Code Y business office.

**Terra Status**

## Terra Data

- Nearly all Terra data products are now available through DAACs. -  CERES, MOPITT and MISR still have unreleased products
- Data product status: check http://eosdatainfo.gsfc.nasa.gov
- Instrument teams should inform community about appropriate uses of Beta and Provisional data products.
- EOS Science Working Group on Data - advocated for increased processing, working on distribution issues and involved in long term archive discussions.
- Terra ASTER data charging plan being finalized by NASA HQ
- EOSDIS recompete being worked.

## Objectives of the EOS Terra Mission

- Provide the first, consistent global “snapshots” of important Earth surface and atmospheric characteristics - extend and improve upon past satellite records.
- CERES – ERBE like Instantaneous and monthly averages validated since March 2000.
- MOPITT – Global example of CO dynamics – no validated data sets.
- MODIS – SST validated Feb. 2002 – for Nov. 2000 to present
- Atmospheric profiles validated Feb. 2002 for Nov. 2000 to present
- Aerosol – Validated Oct. 2001 for Nov. 2000 to present
- Many provisional products

## Improve the ability to detect the human impacts on climate by identifying indicators, or “fingerprints,” of human activity that can be used to distinguish them from natural variability.
MOPITT – global CO – demonstration of annual series.
MODIS – Landuse/Land cover (provisional) , veg. cover conversion ( beta)
Provide measurements of the effects of clouds, aerosol and greenhouse gases on the Earth’s total energy balance.
MOPITT – CO distributions as Beta products, no Methane yet
MODIS – Atmospheric profiles, aerosol, TPW, are validated, provisional products – (cloud and atmospheric products) 
CERES – ERBE like products
Provide estimates of global terrestrial and marine productivity that will enable more accurate calculations of global carbon storage, exchange with the atmosphere, and year-to-year variability.
MODIS – many products in provisional status (e.g., NDVI, landcover, LAI, 	FPAR, ocean chlorophyll, ocean primary productivity)

## Objectives of the EOS Terra Mission

- MODIS – Atmospheric profiles, aerosol, TPW, albedo are validated, provisional products – (albedo, cloud and atmospheric products)
- CERES – ERBE like products
- Contribute to developing improved methods of disaster prediction, characterization, and risk reduction from wild fires, volcanoes, floods, and droughts.
- ASTER – Various volcano Studies, glacier melting
- MISR – Various flood and fire images
- MODIS – Rapid Fire Response System
-              Flood studies
- 	  Snow cover mapping
