RUC BUFR problem w/ analysis data

Hello.
 On Tuesday 8 July, a script problem at NCEP was discovered (and fixed) regarding the RUC BUFR sounding data: The wrong analysis was being included in the BUFR data, taken from an early look analysis at 1200 and 0000 UTC that misses most of the rawinsonde data, rather than the main analysis from which the RUC model is initialized. Take a look at this link to see the before and after difference.

If there had been any impressions that the RUC BUFR soundings were not fitting rawinsonde data very well, this error was probably responsible. It was fixed for the 19z run on Tuesday.

Please post or write if you have any comments or questions.

Stan
