CO 2 Satellite data: Current results and future plans Joanne Skidmore, Sander Houweling, Wouter Hartmann, Ilse Aben Space Research Organization Netherlands
Status of Sciamachy CO 2 retrieval Retrieval at 1.6 m (like OCO but less spectral resolution) Slow start due to a number of complications: - Ice layer growth on channels 7 & 8 (not 6!) - Problems with data distribution - Problems with data processors Recently, good progress First results & interpretation... Note: Sciamachy is not a CO 2 dedicated instrument !
Observed monthly mean CO 2 March 2003
Observed monthly mean CO 2 August 2003
Observed seasonal cycle – N 0-30 N 0-30 S : Max. plausible range
Comparison: Scia CO 2 & TOMS AI July October
Next steps Retrieval issues (e.g. aerosol profiles – MISR data, sensitivity to T) Correlation with other tracers (CH 4, O 2 ) Recurring months of data (reproducibility seems high!) Collaboration with TransCom colleagues ??
