MCST is dedicated to the production of a high quality MODIS calibration product. This product is a precursor to every geophysical science product. MCST works for the Science Team Leader and is responsible for developing and maintaining the calibration product (L1B algorithm).
On June 29, 2021, at 12:20:45z, printed wire assembly (PWA) #47 of the Terra spacecraft buffer failed. This PWA was allocated to the MODIS instrument. Because of this failure, the onboard data storage for MODIS science data has been reduced. On July 2nd, MODIS IOT performed tests on reducing the Terra MODIS data rate to accommodate this change. Starting July 3 at 20:00:00z, the tests were completed, and the data rate continued at the pre-PWA failure schedule, which began on May 2, 2021.
