On October 17, 2016, at 03 Z, the Metop-1 AMSU-A Channel 15 instrument failed.
This degraded the IASI and ATOVS products, and they are not being made. A solution
is being worked on.
Vertical Statistics for ATOVS are generated once a week at approximately 7 am (EST/EDT) on Monday morning using previous week of data. The weekly statistics are generated for the regions 90N to 30N, 30N to 30S, and 30S to 90S over both clear and cloudy conditions.
