Albedo, LAI, and FAPAR satellite-derived ECVs from EUMETSAT LSA-SAF and ECMWF COPERNICUS
Abstract
Land surface albedo, leaf area index (LAI), and fraction of photosynthetically active radiadion (FAPAR) are important variables for the climate community and were therefore defined as Essential Climate Variables (ECVs) by the Global Climate Observing System (GCOS). The two space programs of EUMETSAT (project CDOP3, LSA-SAF) and ECMWF (the Copernicus Climate Change Service; C3S_312a Lot9) are producing these land surface ECVs from data acquired by several spatial missions (METEOSAT, NOAA, METOP, etc.). A portfolio of the ECV products that are made available to the community through LSA-SAF and C3S European programsare presented here.
The LSA-SAF project started in 1999 with research and development activities. The Third Continuous Development and Operations Phase (CDOP-3) started in 2017 and will end in 2022. This project uses data from instruments on board European satellites that were, or will be, launched between 2004 and 2022. In addition to the NRT production of different biophysical variables, a first long term reprocessed time series (called Climate Data Record, CDR) of several of these variables was made available to the community in 2018. The Copernicus/C3S_312a started in 2016, and a second phase (C3S_312b) started in 2018 and will last until 2022. The major objective of C3S_312 projects is to generate CDRs to produce harmonized time series of land surface ECVs from observations coming from various spaceborne sensors (including NOAA/AVHRR series) from the 80's until now. We will present the scientific retrieval algorithms for Land surface albedo, LAI, and FAPAR, the interdependences between these three ECVs, and their maturity level. Furthermore, we will present the development plan for the ECVs retrieval from the next generation of satellites (MTG, EPS-SG, S3, etc.). This work will provide up to 40 years of products characterizing land surface properties, thus allowing the identification and monitoring of human-induced climate change as well as the evaluation of the impact of possible climate mitigation actions.- Publication:
