There was a change in the bias correction and number of radiances accepted 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. It appears that some form of AMSU-A data is now written in the 'airsbufr' file, and this change in input is related to the change in statistics. Operations staff have been alerted and they are currently investigating. | * '''3 November 2011''' - There was a change in the bias correction and number of radiances accepted toward the end of September 2011.
