| DataStreams: | sgpecmwftenX1.c1 |
| Description: | Christian Jakob has found an error in the post-processing code that creates ECMWF diagnostic files for ARM. The sign of the cloud water change term was wrong, and this resulted in erroneous physical tendency terms for temperature and specific humidity. As a result, the advective forcing (which is the difference between the total tendency and physical tendency) cannot be determined. Reprocessing is underway, and the XDC web page will be updated to reflect the availability of corrected tendency files. The additional information on D000726.1 received from Joyce Tichler on 09/06/2000 Christian Jacob has provided us with repaired tendency files for the SGP site for June and July 1997 and these files has been transferred to the Archive. Christian Jacob has provided us with corrected tendency data for June and July 1999 for all ARM areas. These files has been transferred to the Archive. Christian further reports that he is working his way through the periods that Ric Cederwall specified as most urgent to be corrected and will then try and reprocess all data since October 1999. |
