Description: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 matched so that forecasts are not degraded due to dis- similar FOV properties. In this pseudo-observing system simulation experiment (OSSE) study, hyperspectral infrared observations are assimilated to assess the impact of FOV heterogeneity on analyses and forecasts. The Cross-track Infrared Sounder (CrIS) was selected as the representative instrument because it is an operational instrument with the lowest noise. The use of CrIS to this study is only limited to its detector configuration,
