Systematic regional MR to LR Land Coverage

DAP_MG3_01

Europe, continuous wall-to-wall coverage (medium resolution for monitoring of seasonal/annual agricultural land use state and changes) in Reference years 2008-2012.

Africa, continuous wall-to-wall medium and low resolution environmental seasonal / annual change monitoring in Reference years 2008-2012.

This dataset will be built using instruments from
Mission Group 3: Medium-Resolution Land & Ocean Monitoring (imaging multispectral radiometers)

Dataset Composition

Desired product specifications
Products shall be
- TOA reflectances (~L1A)
- L3 (bi-weekly and bi-monthly composites from orthorectified, atmospherically-corrected surface reflectances)
- Geolocation accuracy <80-100m for MR products
- Geolocation accuracy <300m for LR resolution data
- DEM to be used for bi-weekly/bi-monthly composites = GETASSE30
- Projection: "lat-lon geographic WGS 84" for composites
- Format: GeoTIFF for MR composites; HDF for LR composites
- Pre-processing: 300m delivery of bi-weekly and bi-monthly syntheses matching at least the quality achieved for GLOBCOVER (remaining atmospheric noise should not be perceivable in time series profiles of bi-weekly products, spatial patterns due to atmospheric effects must be an order of magnitude lower than the spatial patterns due to the natural landscape).
- SWIR useful for free water detection, mixed vegetation & water detection, discrimination cloud/snow.

Delivery specification
Start delivery:
- 03/2009 delivery for archive data (Europe)
- 12/2008 for new acquisitions (Africa)
- 12/2008 for new acquisitions (Europe)

Timeliness (negotiation ongoing):
- Level1A TOA reflectance in NRT (alternative: Fast24h)
- Level3 daily composite in Fast24h
- Normal for composites (10-daily, bi-weekly and bi-monthly)
- Cumulative for archive
