Observer End-to-End test for IASI

[emilyhcliu]

Configuration

• Test Date is 2021080100
• Model Background: FV-3 6-hour forecast on the cubic-sphere grid
• BUFR Converter :
  • convert scaled radiance ---> radiance
  • Add FOV number mapping (1-120 split into two scans with FOV 1-60)
  • Add conversion of remapped FOV to scan angle
• UFO:
  • Add obs pre filters
    • Add sensor central wavenumber
    • Convert radiance (ObsValue) to brightness temperature (DerivedObsValue)
  • Test with obs prior filters (obs error assignment)
  • Test with obs post filters

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)
