Based on the cognition, a method is developed to assess the retrievability of temperature and the distribution of the global retrievability with HIRS/3 and AIRS data in Jan and Jul are firstly given by using the NCEP reanalysis data. The results show that the retrievability of temperature is low in the upper and lower atmosphere, and high between 400 hPa and 850 hPa. In geographical distribution, the retrievabilities are low in the low latitude marine regions and in some regions in Antarctica, and relatively high in mid-high latitude regions and continental regions.
