MODELLING AND ASSIMILATION: EVALUATION OF MIPAS WATER VAPOURDATA

摘要

At the 2nd Workshop of the Atmospheric ChemistryrnValidation of Envisat (ACVE-2), re-processed waterrnvapour data from MIPAS (V 4.61) were evaluated usingrndata assimilation models. The following groupsrnparticipated: (i) the Data Assimilation Research Centrernin collaboration with the Met Office, both UK; (ii) thernEuropean Centre for Medium-range Weather Forecasts;rnand (iii) the Belgian Institute for Space Aeronomy. Thisrnpaper discusses issues concerning the assimilation ofrnwater vapour in the troposphere and stratosphere, andrnpresents preliminary results from the evaluation of thernre-processed MIPAS water vapour data. This evaluationrnexercise was done under the auspices of the Modellingrnand Assimilation (MA) validation subgroup of thernAtmospheric Chemistry Validation Team (ACVT) forrnEnvisat.
