Daily

The Daily Global Joint Product contains roughly 600 statistical datasets derived from Level-2 MODIS Atmosphere parameters that are summarized over a 24-hour (00 to 00 GMT) period. The ESDT names are MOD08_D3 (Terra) and MYD08_D3 (Aqua).

File Names

L3 CLDPROP (Cloud Properties) File Name Convention

Continuity Atmosphere Product NetCDF4 files are named using a standardized convention as displayed below.

Note that for the filename sample shown below:

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.

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.
