The ECMWF / EUMETSAT NWP-SAF workshop on efficient representation of hyperspectral infrared satellite observations was held from 5 to 7 November 2013.
Description
By making radiance measurements in many thousands of channels, hyperspectral infrared satellite observations such as those from AIRS, IASI and CrIS provide comprehensive and highly detailed information on the atmospheric state and composition. However, exploiting this wealth of information in an efficient manner - that meets the demands of real-time operational NWP and environmental prediction - presents significant scientific and technical challenges. This workshop will focus on optimizing dissemination practices to allow data compression with minimal information loss, together with the development of novel data assimilation techniques that can efficiently convey this information to the analysis.
