Land surface heat and water vapour fluxes are key elements in our climate system: they materialize the feedback the land gives in return to atmosphere. In order to better apprehend the changes of this feedback over the years, a long record of data is necessary. The exploitation of the observations from EUMETSAT METEOSAT suite of satellites could be valuable in that perspective as it provide information for a period in time of about 30 years. The Climate Monitoring (CM) Satellite Application Facility (SAF) has already issued climate data records based on METEOSAT satellites, providing for example different components of the Earth's energy budget. The Land Surface Analysis (LSA) SAF is issuing products for the near-real time applications based on the same platforms: most components of the land surface energy budget are issued, including the instantaneous and daily evapotranspiration rate. In this contribution, we show the result of a feasibility study to combine expertise in both SAFs to provide in the future a climate data record of surface heat fluxes based on METEOSAT satellites.
