## Long term global monitoring of vegetation variables using moderate resolution satellites.

- Aug 8-10, 2006
- University of Montana
- The international workshop will focus on:
- long-term continuity of global vegetation data records
- multi-sensor approaches to vegetation monitoring
- global vegetation monitoring applications to the GEOSS “Societal Benefit Areas”
- strategic planning for future sensors
- Objective: bring researchers together to advance these themes and formulate recommendations for CEOS members and GEOSS.

## Additional Validation issues

- Workshop: Validation of Long Term Vegetation Index Records
- Attached to Montana workshop
- Possibly Monday, Aug. 7, 2006
- Special issue due out in 3-4 months
- Growing season 2006 campaigns should complement NACP intensives
- LAI inter-comparison: paper in special issue, sensitivity analysis starting (Garrigues)
- Land Cover “best practices” document will be published through CEOS

## Land Measurement Teams 

- An on-going process to move from missions to measurements
- Land Measurements spread across focus areas
- Hydrology Focus Area needs to develop a land measurement short-list – we can then explore the cross Focus Area measurement synergies
- Land community to generate ESDR white papers prior to the recompete – resume LMT development after recompete
- First round will focus on Systematic Measurements
- Exploratory Measurements identified but not discussed
- ET – Surface Resistance
- Vegetation Structure
- Soil Moisture
- Canopy Chemistry
- Implications for Future Missions – Decadal Survey

## VIIRS 

- Land EDR evaluation in progress – VIIRS land team workshop on Tuesday pm
- VIIRS instrument challenges but land is optimistic
- Good dialogue ongoing with NGST on algorithm enhancement / improvements (Alain Sei - lead)
- Land PEATE underway – installing early versions of science code for EDR’s
- Land PEATE collaborating with other PEATEs
- Some EDR’s will meet land science needs
- Land PEATE will need to generate/distribute L3 EDR’s
- Land PEATE will need to generate additional land CDR’s
- General Point – greater communication needed between NASA management and the science community re. VIIRS
- Thanks to Bob Murphy for keeping us briefed on NPP progress

## Global Mid-Decadal Data Set 

- This high resolution global data set identified in our early measurement team discussions is an essential input for science and applications
- NASA/USGS initiative getting underway
- Approach Multi-source data set to extend Geocover for 04-06
- Landsat 5, ASTER, EO1, Landsat 7 composites
- USGS working with foreign ground stations
- Preferable  to initiate foreign satellite involvement (CEOS/IGOL)
- Need to evaluate the utility of L7 composites in different environments
- Phase 1 Acquisition underway
- Phase 2 Data Processing needs NASA budgeting 06/07
- joint science and applications support ?
- Community oversight would be beneficial – LCLUC Science Team Meeting March
- Need distributed community capacity for generating regional Landsat Class ( Landsat / ASTER) L3 data sets – free ware – community consensus processing – efforts underway with REASONS, ACCESS
- Combined use of multiple high resolution data sources

## Landsat Continuity 

- OSTP Landsat  memo Dec 23rd
- NASA needs to move quickly to launch the LDCM
- Launch data will determine the length of gap
- Solution will be needed for the data gap beyond 2006 Mid Decadal Data Set
- Landsat 5 continued service?
- Foreign ground stations
- Task ASTER Acquisition
- Foreign satellite data – IRS?  - GEOSS provides the coordination rationale
**General Point **
- Increased NASA dialogue with the community needed  on NASA’s contribution to National GEO and GEOSS
- For example what is GLOS ?
