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
