FTIR Kiruna (& Izana): 7 (2) comparisons with MIPAS version 4.53 (before Nov. 13) around 20 km: MIPAS vmr too low (up to 0.8 ppmv) around 30 km: MIPAS vmr too large (up to 0.8 ppmv) MIPAS columns (integr. prof. >16 km): ~ 10% too large altitude assignment: alt. shift of ~1.5 km MIPAS VMR (p) agrees better than VMR (H)

MWR Payerne: 110 comparisons! with MIPAS version 4.53 before Nov. 13: agreement above ~22 km  altitude: 1 - 2 km after Nov. 13: significant improvement good agreement

26. Page 26 Envisat Validation Workshop, ACVT-GBMCD, MIPAS O 3 12/12/2002 Conclusion Comparisons with MIPAS 4.53 (data from Oct. 24 onwards) using g.b. MWR, LIDAR, FTIR, and O 3 sondes before Nov. 13:  altitude: 1 - 2 km 25 km: MIPAS vmr too large after Nov. 13: O 3 sondes Uccle & MWR Payerne (110 comparisons !) : height assignment is reasonable much better agreement Quality of MIPAS O 3 profiles is quite promising

27. Page 27 Envisat Validation Workshop, ACVT-GBMCD, MIPAS O 3 12/12/2002 Outlook A quantitative validation has to be perfomed Data from MIPAS observations before Oct. 24 are needed More than 1000 files with O 3 profile data on CAL/VAL data base Topics to be addressed: day / night differences latitudinal dependence coincidence criteria: influence of different time and geolocation other MIPAS products (species)
