YAML Configuration | GMI #66
Comments
There is a pending issue (JCSDA-internal/ufo-data#164) that adding bias correction to hofx values before they are used for cloud retrievals. As a result, validation of GMI quality control on-hold at the moment. |
Departures of GMI data in GEOS are fully reproduced in UFO after its bias correction is finalized in UFO. There is git-hub pull request for the latest update: https://github.com/JCSDA-internal/ufo/pull/2179. Here are departure difference ranges and observational error difference ranges: *********** ch01 differences 'UFO_EffectiveError_QC' - 'GsiFinalObsError_QC': -1.90735e-06 1.90735e-06 |
There are a few more data screened out by UFO filters than by GSI. That is because a minor 'bug' in GSI. The retrieval error flag is not checked when clouds are retrieved using simulated Tb and simulated Tb assuming clear-sky conditions.
Only the 2nd ierrret is checked in the GSI program setuprad.f90. |
Waiting for the merge of the UFO PR: https://github.com/JCSDA-internal/ufo/pull/2230 . |
Great stuff @gmao-jjin3! Thanks for working through all the challenges. |
Here is the PR to correctly convert GMI bias correction coefficients: |
@gmao-yzhu @danholdaway The HofX of GMI in x0048 indeed can be reproduce by UFO with CRTM v2.4.0. |
Thanks for checking that out @gmao-jjin3 |
New validation using results of the x0048 experiment. Get the same conclusion as for x0044 in August 2022. GSI results of O-F and QC can be reproduced by UFO, but there are a few more observations tossed by UFO for channels 10-13. The reason was posted in #66 (comment). |
Agreement with GSI using GeoVaLs in UFO (Hofx no bias correction)
Agreement with GSI using GeoVaLs in UFO (Bias correction)
Agreement with GSI using GeoVaLs in UFO (Quality control)
Agreement with GSI using GeoVaLs in UFO (Hofx with bias correction)
Agreement with GSI using Swell
