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.

Cloud Mask not detecting high thick clouds over Weddell Sea (Antarctica) when ice covered

In collection 006, the cloud mask is failing to detect high thick clouds over the Weddell Sea area in Antarctica when it is ice-covered. This represents a small area over very dry conditions. This problem might be fixed in a future PGE03 delivery, until then users should be aware of this shortcoming.

Unstable Atmospheric Profile Retrievals over Antarctica

In collection 006, the cloud mask is failing to detect high thick clouds over the Weddell Sea area when it is ice-covered. This represents a small area over very dry conditions, but it is causing high and noisy retrievals (high standard deviation) in the integrated water vapor values (440-10 hPa) and unrealistic values in the Retrieved Temperature Profiles and Total Ozone. These problem pixels can be filtered out by users with additional sanity checks until it is fixed in the future PGE03 delivery.
