Tracking of known problems and subsequent fixes is an important issue for Continuity Atmosphere data users. This page will act as a repository of all known Continuity Atmosphere Data Product problems, as well as how to determine the problematic version (and the fixed version if available) of the NetCDF4 data -- therefore data users should check this page for updates regularly. Data Users unfamiliar with how to properly track problems and fixes by determining the version of their downloaded NetCDF4 files should refer to the documentation in the Introduction sublink (the top link along the LHS of this page).
Note that a checkmark (✔) in the tables below means Data Issue or Quality Statement applies. A blank means it's been fixed or does not apply.

Issue #1: Degraded Geolocation for VIIRS SNPP data between 20 Dec 2019 and 6 Jan 2020 required reprocessing
Description: SNPP VIIRS Continuity Atmosphere L2 and L3 products had degraded geolocation data during the indicated time period which warranted a reprocessing. Affected products have filenames that begin with AERDB, AERDT, CLDMSK, CLDPROP, and FSNRAD. (Note that FSNRAD is the L2 VIIRS and CrIS fusion product for SNPP and J1 (NOAA-20), where FSN stands for “fusion”.) Version 1.0 data during the indicated time period should be replaced by filenames with creation timestamps on or after January 8th 2020 (2020 008).
