Description 2015-01-13T00:00:00Z
The MODIS Atmosphere Team algorithm developers have released Terra Collection 6 (C6) reprocessing and forward processing product streams. New C6 Level-2 products include aeros ol (MOD04_L2, MOD04_3K), cloud (MOD06_L2), column water vapor (MOD05_L2), and joint (MODATML2) sub-sampled products. Additionally, global browse and Level-3 Terra C6 products have been released. MODIS/Terra C6 algorithms parallel the numerous improvements and data set changes that were reported previously for MODIS/Aqua C6. A complete description of algorithm changes and product details can be found in documents available at http://modis-atmos.gsfc.nas Global L2 browse imagery for many of the key Collection 5 (C5) and C6 atmospheric team datasets are available at
  • The Atmosphere Team Terra C6 L2 cloud mask (MOD35_L2) and atmospheric profile products (MOD07_L2) have also been reprocessed to replace their original 2012 versions in ord er to incorporate Band 5 radiance calibration updates.
  • Atmosphere Team Level-3 (L3) daily products include a small update for Terra to add several new parameter histograms in the daily (MOD08_D3) file. In all other ways, the Terra and Aqua L3 aggregation algorithms are identical.
Production Schedule
MODIS Terra C6 reprocessing for these products began with the beginning of the mission in February 2000 and will continue in chronological sequence through 2014. The Terra C6 forward stream began with Dec 1, 2014. With current processing hardware, it is expected that Terra reprocessing will be completed (i.e., through Dec 1, 2014) in March 2015.
To allow the MODIS community to evaluate and gradually switch over to the C6 products, the C5/C51 forward processing will continue at least one year after the reprocessing of the corresponding C6 products are completed. In addition, the C5/C51 products will be kept in the on-line archive for another year after the C5 forward processing ends. At tha t time, a golden data set of the C5/C51 data will be kept on-line as was done for prior collections.
