KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 2 | F. Hase | IMK-ASF | 05.2008 Towards a retrieval strategy for HYMN To achieve common MWs seems to be the simpler task…* To be included: homogenize constraints. (please refer to IMK-IFU talk on a-priori assumptions) * Error estimation of HYMN FTIR-products: IMK-ASF responsibility – requires definition of retrieval (MWs + constraints) before … Problem: Resulting errors and sensitivities should ideally be part of MW definition process, would require repeated error estimations … (PROFFIT available since 2007 … people encouraged to use it) *: Remember UFTIR experience!

Hase | IMK-ASF | 05.2008 Towards a retrieval strategy for HYMN Of equal importance as error characterisation: minimize errors! Current topics and preliminary answers: Temperature error ECMWF instead of NCEP ECMWF data superior … or just different?

Hase | IMK-ASF | 05.2008 Towards a retrieval strategy for HYMN In case of O3, it has been shown that including T-fit improves Results (over use of local daily sonde-T) Include CO2 MWs for T-fit (extra bonus: airmass check via CO2) MWs: (962.5000000,964.5000000)CO2/T (964.2500000,965.2000000) CO2/T (967.2000000,968.2500000) CO2/T (968.7000000,969.6000000) CO2/T (1202.500000,1204.500000)CH4 (UFTIR MCT) (1207.600000,1208.100000) CH4 (UFTIR MCT) (1221.561111,1223.261111) CH4 (UFTIR MCT)
