Description
This dataset provides a long-period estimation of global land evapotranspiration over two resolutions: (1) 0.1°-8day-average resolution, covering 2001-01-01 to 2019-08-29; (2) 0.25°-Daily resolution, covering 1981-01-01 to 2020-12-31. The product was merged using a collocation-based approach. The inputs included: (1) ERA5-land-hourly total evaporation products; (2) Penman-Monteith-Leuning Evapotranspiration V2 (PMLV2); (3) The FluxCom-RS ensemble of global energy flux; (4) the Global Land Evaporation Amsterdam Model version 3.3a (GLEAMv3.3a); (5) The Global Land Data Assimilation System-Noah model (GLDASv2.1 Noah). Five collocation algorithms were used for characterizing the uncertainties of inputs. And the optimal weights of each product were calculated by minimizing the mean square error based on the error information. The CAMELE product was further evaluated against 82 FLUXNET sites and showed average R2 value of 0.73 and 0.68 over 0.1° and 0.25° resolutions, respectively. CAMELE ET can be used for hydrological studies and regional investigation of water resources management, etc. For further information, please check our related publication.
Section A : 0.1°-8day-average resolution from 2001 to 2019. (10.5281/zenodo.6616791)
Section B: 0.25°-daily resolution from 1981 to 2020. (10.5281/zenodo.6616815)
