The 2nd ERA-CLIM2 General Assembly was held at EUMETSAT on 9-11 December 2015.
The main goal of ERA-CLIM2 is to apply and extend the current global reanalysis capability in Europe, in order to meet the challenging requirements for climate monitoring, climate research, and the development of climate services. The five main objectives for the ERA‐CLIM2 project (see Section B1.1 of Annex I of the Grant Agreement) are:
- Production of an ensemble of 20th-century reanalyses at moderate spatial resolution, using a coupled atmosphere-ocean model, which will provide a consistent data set for atmosphere, land, ocean, cryosphere, including, for the first time, the carbon cycle across these domains;
- Production of a new state-of-the-art global reanalysis of the satellite era at improved spatial resolution, which will provide a climate monitoring capability with near-real time data updates;
- Further improvement of earth-system reanalysis capability by implementing a coherent research and development program in coupled data assimilation targeted for climate reanalysis;
- Continued improvement of observational data sets needed for reanalysis, in-situ as well as satellite-based, with a focus on temporal consistency and reduction of uncertainties in estimates of essential climate variables;
- Development of tools and resources for users to help assess uncertainties in reanalysis products.
The 2nd General Assembly will provide the ERA-CLIM2 partners and contributors the forum to assess progress since the 1st General Assembly, discuss open and outstanding scientific and technical issues, and plan how best to advance work to achieve its objectives.
