C3S2_313g LOT 1 Products and Services for additional ECVs in the Land and Ocean Domains

ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), invites Tenders aiming to expand the scope of climate information delivered in the Land and Ocean domains by incorporating products and services for additional Essential Climate Variables (ECVs) split into five distinct Lots, specifically for Sea Surface Salinity (Lot 1), Permafrost (Lot 2), Above-Ground Biomass (Lot 3), Surface Albedo (Lot 4), Leaf Area Index (LAI) and Fraction of Absorbed Photosynthetically Active Radiation (fAPAR) (Lot 5).

For each Lot, ECMWF intends to award a single Framework Agreement for a period of 30 months, which shall be implemented via a single Service Contract (unless multiple Lots are awarded to the same Tenderer) expected to commence in January 2026. Tenderers are invited to submit their Tenders for any one of the Lots, or any combination of multiple Lots (with each submission to be done separately). Participation in multiple Lots in a non-lead capacity (e.g. as a subcontractor or supporting entity) is also permitted. The evaluation of bids will be conducted per Lot.

Lot 1: Sea Surface Salinity

In this Lot, the Sea Surface Salinity ECV Product is the priority. Tenderers shall provide a self-assessment of current maturity levels for each proposed ECV product, based on the maturity matrix presented in Bates and Privette, (2012), together with a plan for increasing maturity levels in order to attain Full Operation Capacity for each product. Priority must be given to monthly averaged L3 and/or L4 products enabling multi-decadal assessment of long-term climate variability and trends. The proposed products must benefit from scientific advances made in relevant research projects (e.g. the ESA-CCI Sea Surface Salinity project or other relevant projects in this context).
