Missing Terra Data between 5 Aug 2017 and 6 Aug 2017

Description: Following the Terra Deep Space Calibration on August 5th, 2017 (2017 217) there were some faulty C6 Terra MODIS Atmosphere data as the focal plane temperatures did not return to nominal values until the day after - August 6th, 2017 (2017 218) 1420 UTC. So the granules for the time period between 2017 217 23:00 UTC and 2017 218 14:15 UTC were removed before the downstream Atmosphere processing. Data users will notice missing MODIS Atmosphere Data during this period for all Level-2 (L2) and Level-3 (L3) Daily atmosphere products.

Problems in input 04_L2, 05_L2, 06_L2, 07_L2, and 35_L2 propagate into downsteam products

See the Known Problem pages for the input Level-2 products 04_L2 (Aerosol), 05_L2 (Water Vapor), 06_L2 (Cloud), 07_L2 (Profiles), and 35_L2 (Cloud Mask) by clicking on the links to the left. Any problem in these upstream products will propagate downsteam.  Users should be aware of any issues in the upstream products.

Missing Granules/Orbits in Sep-Nov 2014 Aqua Data

Incorrect production rules in MODAPS caused the initial release of Aqua MOD08_D3 data to be missing some granules/orbits in the September to November 2014 time period. Data was rerun and new corrected files are now available for download. Since a picture is worth a thousand words, an example animation showing this problem (before and after correction) is displayed below. Just to clarify, this was not a software/code bug, but instead a problem in the operational production rules.
