A 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 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...
متن کاملRetrieval of daytime total columnar water vapour from MODIS measurements over land surfaces
A retrieval of total column water vapour (TCWV) from MODIS (Moderate-resolution Imaging Spectroradiometer) measurements is presented. The algorithm is adapted from a retrieval for MERIS (Medium Resolution Imaging Spectrometer) from Lindstrot et al. (2012). It obtains the TCWV for cloud-free scenes above land at a spatial resolution of 1 km× 1 km and provides uncertainties on a pixel-by-pixel ba...
متن کاملATSR Total Water Vapour Content Retrieval and Comparison with GOME and ATSR Microwave Sounder Data
The Water Vapour estimation from satellite data has been widely discussed in past years and different IR based techniques have been approached by various authors. In our work we estimate the total content of water vapour over sea surface by using ATSR-2 (Along Track Scanning Radiometer) Infra Red imagery. Two different retrieval methods have been applied: one proposed by Ottlé [1] in 1997 and t...
متن کامل3-D Atmospheric Moisture Retrieval using GNSS
Water vapour, one of the dominant greenhouse gases, is a highly variable constituent of the Earth's atmosphere with a high latent heat. These two factors give it a key role in the development of atmospheric dynamics. Knowledge of the behaviour and distribution of water vapour in the atmosphere is crucial for understanding and predicting weather and climate. Unfortunately, atmospheric water vapo...
