b. An Example Software Patch: L3 sub-sampling and dead detector issue
Using the old L3 Logic, when sub-sampling … dead Aqua detectors for 1 km aggregated Band 6 Detector 1 2 3 4 5 6 7 8 9 10 « Dead detector « Dead detector caused all-fill L3 parameters(that used band 6 as input) Code patch now allows a PCF specified start line for sub sampling – changed from “3” to “4” for C005. (note that start pixel remains at “3” and stride remains at “5”)
c. A Software Patch Under Development: Screen L2 Cloud Optical Thickness “partial retrievals” from L3 (est. completion: end of January 2006)
Topic 2. Recent high-profile additions to the MODIS-Atmosphere Web Site modis-atmos.gsfc.nasa.gov
b. New “Greatly Enhanced” QA Plan for Collection 005
