We found that AMSU-A data is now written in the 'airsbufr' file; this change in input is likely related to the change in statistics.

Aqua AMSU-A change starting 18z Sep 21 2011
- 3 November 2011 - There was a change in the bias correction and number of radiances accepted for Aqua AMSU-A toward the end of September 2011. A closer check showed the bias correction adjusted starting at 18z Sep 21 2011. The mean (O-F) and (O-A) increased to -0.2K and normalized cost also increased. In the ana.log files after that point, it shows we are reading AMSU-A data from both the 'airsbufr' and 'eosamsuabufr' files while prior to that date there was no AMSU-A data read in from the 'airsbufr' file. We found that AMSU-A data is now written in the 'airsbufr' file; this change in input is likely related to the change in statistics. Operations staff have been alerted and they are currently investigating.
- 3 November 2011 - Update - our upstream provider had applied an update to their processing package back in September which added the AMSU-A data to the AIRS data file. OPS configuration is being modified not to try to read AMSU-A from the AIRS data file, and we have also asked our data provider to revert to our prior configuration.
- 7 November 2011 - It looks like the statistics (bias correction and o-f mean) have moved back toward their previous values.
