Atmospheric composition
The goal of this part of the work is, by developing an integrated approach to the analysis of satellite measurements, to provide new information on atmospheric composition for air-pollution forecasting and testing climate models. Current work includes:
- Development of individual sensor retrievals schemes, validation and intercomparisons focusing on MetOp satellite and ACE and MIPAS instrument on ENVISAT
- Use of chemical transport models (CTMs): TOMCAT and GEOS-Chem
- Initial comparisons of upper troposphere organics from CTM with limb-sounders
- Initial development of inverse modelling for CO, CH4 and CO2
- Development of Ensemble Kalman Filter assimilation tools for methane and shorter-lived gases
- Development of observation operators for MetOp and Envisat, initially for CTM comparisons on common basis and subsequently for assimilationFurther development of the nudged version of the coupled chemistry-climate model (CCM): UKCA
- Satellite observation operators for CCM comparisons on SCISAT-1/ACE, Envisat/MIPAS and ERS-2/GOME-1.
