Online domain check for satellite radiance data

[xyzemc]

The online domain check filter has been tested for atms_npp, atms_n20, and amsua_n19. The yaml file for applying domain check for satellite radiance is as bellow:

   - filter: Bounds Check
     filter variables:
     - name: brightnessTemperature
       channels: *atms_npp_channels
     test variables:
     - name: GeoVaLs/observable_domain_mask
       flag all filter variables if any test variable is out of bounds: true
       minvalue: 0.0
       maxvalue: 0.5

Example: atms_n20

After QC:

In the above figures, the dark blue color represent the data kept after domain check. So the data points outside of the domain are still kept in hofx file and filled with missing value, instead of completely removed. The previous 'circle domain check' filter does not remove the data outside of the domain either. With the filtered data kept in the memory, the size of output hofx file become very large. We need to address this problem with a long-term solution considering the operational implementation.
