Investigating the Sensitivity of NCEP's GFS to Potential Detector Heterogeneity of Hyperspectral Infrared Sounders

Earth and Space Science, 2022
Infrared sounding instruments use large arrays of detectors to make simultaneous observations in multiple field‐of‐view (FOV). For Numerical Weather Prediction (NWP) models to assimilate multiple detector observations, FOV responsivities should be well ...
