ECMWF-AUX 007 issue

Back to issue list
Issue:Artifacts in vertical profiles of temperature, specific humidity, and ozone

Opened:01/26/07 3:30 pmSubmitted by:Phil Partain
Severity:NORMAL Planned resolution: Fix in R04


Description
An error in the reduction of 91 ECMWF layers to 60 layers results in oscillations or artifacts in the vertical profile of temperature, specific humidity, and ozone. The affect on temperature is small at about +/- 0.5 K, however applications that use temperature differences between levels (for example the 2B-FLXHR heating rate calculation) can exhibit amplified errors. As a result, the 2B-FLXHR product for R03 uses a corrected beta version of the ECMWF-AUX product as input, not the current version 007.
