Retrieval of temperature and moisture profiles from AMSU-A and AMSU-B measurements
The NOAA-15 weather satellite carries the Advanced Microwave Sounding Units-A and -B (AMSU-A, AMSU-B) which measure thermal emission from an atmospheric oxygen band, two water lines, and several window frequencies. An iterated minimum-variance algorithm retrieves profiles of temperature and humidity in the atmosphere from this data. Relative humidity is converted into absolute humidity with use...
متن کاملSCIAMACHY water vapour retrieval
Global water vapour column amounts have been derived for the first time from measurements of the SCanning Imaging Absorption spectroMeter for Atmospheric CHar-tographY (SCIAMACHY) on the European environmental satellite ENVISAT. For this purpose, two different existing retrieval algorithms have been adapted, namely the Air 5 Mass Corrected Differential Absorption Spectroscopy (AMC-DOAS) which w...
متن کاملA microwave satellite water vapour column retrieval for polar winter conditions
A new microwave satellite water vapour retrieval for the polar winter atmosphere is presented. The retrieval builds on the work of Miao et al. (2001) and Melsheimer and Heygster (2008), employing auxiliary information for atmospheric conditions and numerical optimization. It was tested using simulated and actual measurements from the Microwave Humidity Sounder (MHS) satellite instruments. Groun...
متن کاملThe Passive microwave Neural network Precipitation Retrieval (PNPR) algorithm for AMSU/MHS observations: description and application to European case studies
The purpose of this study is to describe a new algorithm based on a neural network approach (Passive microwave Neural network Precipitation Retrieval – PNPR) for precipitation rate estimation from AMSU/MHS observations, and to provide examples of its performance for specific case studies over the European/Mediterranean area. The algorithm optimally exploits the different characteristics of Adva...
متن کاملInteractive comment on “A microwave satellite water vapour column retrieval for polar winter conditions” by C. Perro et al
Referee: This article describes an updated retrieval method to obtain water vapour columns in polar regions from the MHS and AMSU-B instruments. The improvements to current methods are described and the new method tested against synthetic and real data. The new method involves using a-priori information and iterating a radiative transfer model to optimise the optical depth profile by scaling th...
