C3S2_314_bis Support for Climate Reanalysis including Satellite Data Rescue

Description du marché

The objective of this contract is to prepare a selection of early satellite data records for use in future climate reanalyses. Activities in C3S2_314_bis shall build on the outcomes of previous Satellite Data Rescue Service Contracts in Copernicus Phase 1 (COP1, C3S_311C Lot 1, 2018-2021) and Phase 2 (C3S2_314, 2022-2024), as well as on the earlier FP7 ERA-CLIM and ERA-CLIM2 projects (www.ecmwf.int/en/research/projects). In COP1, datasets for a list of instruments prioritised by the ERA-CLIM projects were recovered, assessed and delivered to ECMWF. Several additional issues, detailed in supporting documents (Draft Algorithm Theoretical Basis [ATBD] documents), were identified which require additional analysis and development work, beyond the scope of COP1. The consolidation of the products delivered in COP1, to facilitate their assimilation in global reanalyses, was an important aim of the COP2 contract, C3S2_314. A second objective involved the recovery and assessment of new datasets from additional sensors identified in earlier projects and confirmed in the data inventory activity of COP1. The further consolidation of these datasets, including support for the assimilation of these datasets in the ECMWF Integrated Forecasting System through targeted developments in the IFS, is an important goal of this contract. Requirements for the recovery, development and assessment of several new datasets have also been identified and form an additional set of requirements set out in this ITT. The products prepared and delivered in C3S2_314_bis shall be used as input for future climate reanalyses, including the next-generation C3S global reanalysis, ERA6, which is scheduled to go into production in 2025. ECMWF intends to award a single Framework Agreement for a period of maximum 36 months, which shall be implemented via a single Service Contract expected to commence in Q2 2025.
