- "Estimation of the errors for NASA version 5 retrievals (from AIRS/AMSUA) over the high southern latitudes". Results by February 2009.
*# Starting point: the QC flags and error estimation from the extensive CalVal effort for NASA v5 retrievalsThe purpose of this study is to define objectively the observation error covariance matrix for future assimilation experiments within WRF-Var. I'll compare these results with an other method implemented inside WRF-Var.
- Products: profiles of variance for temperature/humidity + estimation of vertical correlation of errors
- Method: comparison with collocated radiosonde + GPS retrievals (reduced to similar vertical resolution)
- Period: depending on the number of collocated data (e.g. for 1 month in the summer and 1 month in the winter)
- Stratification of results: error estimation for separate:
+ NASA QC flags
+ snow/sea_ice/sea surface
+ clear/cloud top (e.g. low_cloud/mid_cloud/high_cloud)
+ ...
- Incorporate MODIS retrievals into WRF-Var v3.0 code. Regular updates to Tom on radiance developments.
