I’ve just run into a problem when I apply obs filtering in the hyb-3dvar_gfs_aero.yaml file that didn’t occur before. And I wonder if recent changes to the .nc4 file structure are the cause. When I try to filter obs using “Domain Check”, I get undefined (meaning e+38) values for oman and hofx1. Have there been changes that would cause the following yaml section to fail?
obs operator:
name: AodCRTM
Absorbers: [H2O,O3]
obs options:
Sensor_ID: v.viirs-m_npp
EndianType: little_endian
CoefficientPath: Data/crtm/
AerosolOption: aerosols_gocart_default
obs error:
covariance model: diagonal
obs filters:
- filter: Domain Check
filter variables:
- name: aerosol_optical_depth
channels: 4
where:
- variable:
name: latitude@MetaData
minvalue: 0
