Abstract: [1] A neural network retrieval method has been applied to investigate AMSU-A/ AMSU-B atmospheric temperature and humidity profiling capabilities over land. The retrieval method benefits from a reliable estimate of the land emissivity and skin temperature as well as first guess information regarding the temperature-humidity profiles. It has been applied on a large geographic area (60°W-60°E, 60°S-60°N) and atmospheric situations (winter and summer). The retrieved RMS errors are within 2 K and 9% in temperature…
