2008 Feb 6 MODSCAG

Timeline
MODSCAG processing 32 scenes for validation (Peter)
MODIS cloud masking - Monday/Tuesdsay (Ceretha)
filtering (water,cloud,shadow (TM only),elevation(vary by lat/long/season?) for MODIS and TM - Monday (Karl)
Steps of analysis - next week (Jeff)

Topics:

Application of 1 km land/water map
Application of 30 m (up to 500 m) land/water map that Karl has for CONUS (?).

(Painter pushes for using this in CONUS and 1 km map outside CONUS)

Final product formats (e.g. do we follow the format used in MOD10A1?)

Cloud mask for MODIS
- do we only need to cloud mask TM area, should we mask the whole scene?
- what do we distribute?
  - masked MODSCAG and unmasked?
- are we just masking for validation images?
- MODSCAG reprocessing
  - priority list for ROIs/dates

TM edge mask - see:

Distributed products
- Jeff's time/space product
- make other products available for legacy purposes
  - raw modscag
    - has false positives
      - not filtered out by time/space interpolation - it is only additive

MODSCAG processing
- 3 steps
  - Creating raw modscag
  - removing false positives
    - threshold
      - Jeff says shouldn't just pick a number, we should decide based on TM validation
    - elevation
      - dependant on latitude and season
    - water mask
      - do we use 30m CONUS or 1km NASA
        
        30m for CONUS, neighborhood operation for world
  - time/space interpolation
