An extension to the two-step physical retrieval algorithm was developed. Combined clear-sky multitemporal and multispectral observations were used retrieve atmospheric temperature-humidity profile, land-surface temperature, surface emissivities in midwave (3–5 µm) long-wave (8–14.5 regions. The extended tested with both simulated real data from Moderate-Resolution Imaging Spectroradiometer (MODIS) Airborne Simulator. A sensitivity study error analysis demonstrate that performance is improved by algorithm. relatively insensitive uncertainties for observations. also applied MODIS daytime nighttime showed it capable of retrieving medium-scale temperature water vapor emissivity accuracy similar achieved Geostationary Operational Environmental Satellite (GOES) but at a spatial resolution higher than GOES.
