MIPAS OZONE ASSIMILATION

摘要

Four data assimilation systems have been workingrnextensively on MIPAS ozone data. These are: DARC,rnECMWF, GMAO and BASCOE. All assimilationsrnsystems were prepared to contribute to the CAL/VALrnworkshop. The MIPAS data are version 4.61. The DatarnAssimilation Research Centre (DARC), EuropeanrnCentre for Medium – Range Weather Forecastsrn(ECMWF) and the Global Modelling and AssimilationrnOffice (GMAO), assimilated MIPAS ozone data inrnaddition to other observations containing ozonerninformation. BASCOE (Belgian Assimilation Systemrnof Chemical Observations from Envisat) assimilatedrnonly MIPAS observations. The overall findings are arnbetter MIPAS ozone quality, with less contaminatedrndata. The MIPAS data lead to an overall improvementrnof the ozone analyses with respect to independent data.
