Collection 7

Collection 7 (C7) has been under development for the last several months. MCST, in consultation with representatives of the science disciplines, developed improvements to the calibration algorithms and methodologies to handle known issues with the aging MODIS sensors. Per the previous discussion, MCST plans to deliver a final set of C7 LUTs in March, 2021 which will be followed by regular forward LUT updates to maintain continuity. The reprocessing and forward production of C7 Level 1B is expected to begin in March, 2021. In preparation for the C7 L1B code and LUT release, MCST has provided three technical memos summarizing the code changes and algorithm enhancements.
