Abstract: The neural network technique has been used to retrieve atmospheric temperature and moisture profiles using Advanced Microwave Sounding Unit (AMSU) measurements onboard National Oceanic Atmospheric Administration (NOAA K, L and M) satellites over Indian region in real time. In the present study, an attempt has been made to inter-compare these profiles, which are being generated from two different sets of spectral wavelengths-one from infrared and the other from microwave. These inter-comparisons have been made for the month of January and August 2004. It has been found that in general, the temperature and moisture profiles retrieved using microwave data at India Meteorological Department (IMD), New Delhi, are comparable with the temperature and moisture profiles from advanced infrared sounder (AIRS) data.
