The CIMR L2PAD project focuses on Level-2 products under ESA’s operational responsibility, that is Level-2 products in the Polar Oceans (incl. sea ice) and Global Land (incl. lakes) family. The Global Oceans and Atmosphere products are not covered, as they are under EUMETSAT’s operational responsibility.

The table below lists the Level-2 products that are covered by the CIMR L2PAD team (-P: Polar Oceans, -L: Global Land).

Depending on the Level-2 product, different delivery timeliness are specified:

  • Near-Real-Time-3-Hour (NTR3H): Product delivered in <3 hour to the point of user pickup after data acquisition by the satellite. This is the nominal timeliness for the Copernicus Space Component.
  • Near-Real-Time-1-Hour (NRT1H): Product delivered in <1 hour to the point of user pickup after data acquisition by the satellite. In the case of CIMR, NRT1H targets support to safe Arctic navigation.
  • Non-Time-Critical (NTC): Product delivered in less than 30 days to the point of user pickup after data acquisition by the satellite.

MRD‑XXXX refers to the requirement number in the CIMR Mission Requirement Document v5.
