The promote ozone profile service - Long-term 3D ozone reanalysis of ERS-2 and enivsat data sets
Coupled chemistry-climate models
Data assimilation systems
MetadataShow full item record
The service aims at providing a global reanalysis of ozone and related conservative and reactive species in the stratosphere by exploiting observations from ERS-2/GOME, ENVISAT/MIPAS, SCIAMACHY and GOMOS as well as UARS/MLS. The target period covers the years 1992 to present will be covered. In order to derive a global consistent record of stratospheric ozone chemistry an ensemble of data assimilation systems is applied. This suite comprises a Suboptimal Kalman-Filter (KF) using ROSE/DLR and four-dimensional assimilation (4D-Var) systems SACADA and BASCOE. The service is part of the GSE PROMOTE portfolio. PROMOTE is the GMES Service Element (GSE) for the Atmosphere (http://www.gse-promote.org). Reanalysis results are presented as well as first applications on the evaluation of coupled chemistry-climate models.
