Datasets ET SEN4ET

This dataset contains detailed metadata for the SEN4ET project, developed under the ET4DROUGHT initiative. It includes information about evapotranspiration (ET) estimation using remote sensing and meteorological data for two zones in Catalonia: Lleida and BaixTer, covering the period 2017–2024. The metadata describes: Spatial and temporal coverage of all datasets. Coordinate Reference Systems (CRS) used for each product. Spatial extent and dimensions for each zone and dataset. Folder structure and file naming conventions. Products and variables from Sentinel-2, Sentinel-3, ERA5, CAMS, and TSEB-based ET models. File formats (NetCDF, GeoTIFF, CSV, GeoJSON) and resolutions (20 m for most datasets, 1 km for Sentinel-3 LST, ~45.8 km for ERA5/CAMS). Processing details including gap-filling strategies and model outputs (TSEB, SW, PM). This metadata ensures FAIR principles (Findable, Accessible, Interoperable, Reusable) for the SEN4ET dataset and supports reproducibility of ET modeling workflows. This repository also contains sample files to illustrate the structure and format of the SEN4ET dataset, including: sen4et_metadades.txt: The complete metadata file. output_S2.zip: Example files from the SENTINEL-2 BIOPHYSICAL DATASET. output_S3.zip: Example files from the SENTINEL-3 LAND SURFACE TEMPERATURE DATASET. Meteo_Lleida_2022.zip: Example files from the METEOROLOGICAL DATASETS. pyTSEB_20220609_HR.nc: Example file from the INPUT DATASET – HIGH RESOLUTION (HR). 20220609_ET_TSEB_PT_LST_DT_HR.nc: Example file from the ET OUTPUT PRODUCTS. 20220609_ETa_pond_Lleida.nc: Example file from the ETa_pond PRODUCTS. Three GIF files illustrating time series examples derived from this dataset.
