Spatial interpolation data of groundwater level in the main stream of the Tarim River (2012-2021),Geotiff format, spatial resolution
ETMonitor The global daily 1-kilometer resolution actual surface evapotranspiration data set is calculated based on ETMonitor, a multi-parametric surface evapotranspiration remote sensing estimation model suitable for different land cover types. The remote sensing data mainly used for the input data include GLASS products.(Leaf area index, vegetation cover and albedo), MODIS products (surface cover, snow cover), dynamic surface water cover, ESA CCI soil moisture, GPM precipitation, etc., combined with the ERA5 global atmospheric reanalysis data of the European Center for Medium-Range Weather Forecasting.
The ETMonitor model is used to estimate vegetation transpiration, soil evaporation, canopy precipitation interception and evaporation, water surface evaporation, and ice and snow sublimation on a daily scale at a 1-kilometer resolution pixel scale, and each component is summed to obtain daily evapotranspiration per pixel. Direct verification was carried out using FLUXNET and other ground observation data. The estimated results were in good agreement with the ground measured data. The daily evapotranspiration verification RMSE was 0.93 mm/d, the error was 0.08 mm/d, and the correlation coefficient was 0.75. This dataset applies cumulative sum to the daily evapotranspiration values estimated by ETMonitor to obtain monthly evapotranspiration, which is converted into latitude and longitude projections for public release. This dataset covers the world, with a time step of each month, a spatial resolution of 1 kilometer, and a unit of mm/month. The data type is integer, a scaling factor of 0.1, and invalid values are filled in-1.
