Observer End-to-End test for ATMS/AMSU-A

[emilyhcliu]

Configuration

• test date is 2021080100
• Use antenna temperature (Ta)
• ATMS is FFT remapped

Test using fv3jedi_hofx_nomodel.x with the IODA files converted from BUFR converter

• Convert BUFR to IODA format using bufr2ioda.x with YAML
• Transform FV3 background to GeoVaL
• Run UFO HofX
• Run UFO HofX with QC (without thinning)

Check List

BUFR Converter YAML -- Updated YAML files are in feature/iodaconv_gdasapp

• [x] ATMS YAML
• [x] AMSUA (all except n15) YAML Note: AMSUA n15 BUFR contains brightness temperature

Investigate diag output from UFO

• [x] ATMS HofX
• [x] ATMS HofX + QC
• [x] AMSUA HofX
• [x] AMSUA HofX + QC
• [ ] AMSUA Obs Error
• [ ] ATMS Obs Error

ATMS

Sanity Check for ATMS Remapping (using Channel 10 as an example)

Original O-F (no bias correction) --- Channel 10

Remapped O-F (no bias correction) --- Channel 10

Check UFO diagnostic output (using channels 2 and 10 as examples)

Remapped O-F with Bias Correction --- Channel 10

Remapped O-F with Bias Correction + QC --- Channel 10

Remapped O-F without Bias Correction --- Channel 2

Remapped O-F with Bias Correction --- Channel 2

Remapped O-F with Bias Correction + QC --- Channel 2

UFO work needs to be completed before testing the cycling of bias correction:

1. Add the antenna pattern weighted surface properties in each FOV (Check with JCSDA for a valid branch for testing) --- 2nd priority
2. Add data thinning --- 1st priority

AMSU-A

Check UFO diagnostic output (using channels 2 and 9 as examples)

O-F without bias correction --- Channel 9

O-F with Bias Correction --- Channel 9

O-F with Bias Correction + QC --- Channel 9

O-F without Bias Correction --- Channel 2

O-F with Bias Correction --- Channel 2

O-F with Bias Correction + QC --- Channel 2

UFO work needs to be completed before testing the cycling of bias correction:

1. Add the antenna pattern weighted surface properties in each FOV (Check with JCSDA for a valid branch for testing) --- 2nd priority
2. Add data thinning --- 1st priority
