Interim Report on GOSAT/TANSO Project 2014

The research project "Application of KLIMA algorithm to CO2 retrieval from IASI/METOP-A observations and comparison with GOSAT/TANSO-FTS products" aims at the application of the KLIMA inversion algorithm, integrated into the ESA G-POD (Grid Processing On-Demand) operational environment, to processing of IASI/METOP-A spectra and at the retrieval of carbon dioxide columns for comparison and cross-validation with GOSAT TANSO-FTS products. According to the original planning, the activities of the project have been developed in two phases. The objective of Phase 1 has been the development of a prototype software for the retrieval of CO2 columns from IASI data with performance suitable for the comparison with TANSO-FTS products and with basic features meeting the requirements of the integration on G-POD. Phase 1 has been successfully completed. The objectives of Phase 2 are the procurement of a consolidated version of the KLIMA-IASI/G-POD retrieval code, the processing of IASI spectra for XCO2 retrieval and the comparison and cross-validation with TANSO-FTS SWIR XCO2 products. Phase 2 started in June 2010 and it is now completed. In this report, we describe the activities conducted in the final stage of the project and summarize our conclusion. Moreover, we report about our request for extension of one year of the contract to conduct a comparison of KLIMA-IASI products with Level-2 data from TANSO-FTS TIR measurements.
