| Zusammenfassung |
| Summer 2017, the TROPOMI instrument will be launched as payload of the Sentinel-5
Precursor mission. The instrument comprises a shortwave-infrared spectrometer module
observing Earthshine radiances around 2.3 μm. Based on these measurements, data
exploitation will provide users with the global total column distribution of methane, carbon
monoxide, water vapor and its isotope HDO. In this presentation, we will discuss the results
of our ten years’ mission preparation to infer these atmospheric abundances for operational
and scientific purposes. The main challenge of the processor development is to ensure the
required data quality without exceeding the computational constraints of the processing
facility. We discuss the algorithm baseline and the processor performance for the SWIR trace
gases including an estimate of the data quality based on simulated measurements. Moreover,
to demonstrate the maturity and heritage of the algorithms, we show recent applications to
GOSAT and SCIAMACHY measurements and the verification with on-ground validation
measurements. |
