C3S_311c LOT 2 Support for climate reanalysis including satellite data rescue

Tender description

ECMWF as the Entrusted Entity for the Copernicus Climate Change Service (C3S) invites tenders for activities to support climate reanalysis by extending the coverage and quality of input data from the data-sparse past. The overall objective for this set of services is to improve and harmonise access to the early (pre-1979) instrumental record. Deliverables shall be used as input for future climate reanalyses, including the next-generation C3S global reanalysis ERA6 which is scheduled to go into production by 2021. Access to all datasets and associated documentation shall be provided via the C3S Climate Data Store. Lot 2: Historic upper-air data ECMWF intends to award a framework agreement with a single multi-annual service contract (maximum duration of 34 months and an end date not later than 30 June 2021) for development and maintenance of a quality-controlled global database containing all known digitised in-situ upper-air weather observations made prior to 1979, together with metadata and information needed for data assimilation such as bias adjustments and uncertainty estimates. The objective is to provide C3S users with access to quality-assured observations of upper-air weather data for temperature, wind and humidity.
