Division (2) Climate reanalyses

United Kingdom

Original text. Later amendments are not shown.

This component shall provide resources for technical development, production, monitoring, evaluation and delivery of the following:

  1. (a)

    the following global climate reanalysis datasets and products:

    1. (1)

      an atmospheric reanalysis covering a minimum of 30 years designed for near real time (less than 5 days) monitoring of the climate system based on the comprehensive global observing system, including in-situ and satellite observations;

    2. (2)

      extended (> 100 year) reanalyses of the coupled climate system;

    3. (3)

      derived high-resolution global reanalyses of the ocean and land surface Meteorological information from atmospheric reanalyses shall be used to derive consistent estimates of terrestrial and ocean ECVs at high spatial resolution (initially 16 km);

  2. (b)

    regional climate reanalysis datasets and products.

Reanalyses shall be produced by assimilating high-quality climate observations in a coupled atmosphere/land/ocean/sea-ice model compatible with the ECMWF Seasonal Prediction System. Regional reanalysis shall use of high-resolution observations and shall provide data products at higher resolution for the European region than global reanalyses. A refresh cycle of approximately five years shall be established to benefit from all inputs contributing to the generation of regional reanalyses.
