OpenET DisALEXI Monthly Evapotranspiration v2.0
Atmosphere-Land Exchange Inverse / Disaggregation of the Atmosphere-Land Exchange Inverse (ALEXI/DisALEXI) DisALEXI was recently ported to Google Earth Engine as part of the OpenET framework and the baseline ALEXI/DisALEXI model structure is described by Anderson et al. (2012, 2018). The ALEXI evapotranspiration (ET) model specifically … evapotranspiration gridmet-derived landsat-derived monthly openet water -
OpenET eeMETRIC Monthly Evapotranspiration v2.0
Google Earth Engine implementation of the Mapping Evapotranspiration at high Resolution with Internalized Calibration model (eeMETRIC) eeMETRIC applies the advanced METRIC algorithms and process of Allen et al. (2007; 2015) and Allen et al. (2013b), where a singular relationship between the near surface air temperature … evapotranspiration gridmet-derived landsat-derived monthly openet water -
OpenET Ensemble Monthly Evapotranspiration v2.0
The OpenET dataset includes satellite-based data on the total amount of water that is transferred from the land surface to the atmosphere through the process of evapotranspiration (ET). OpenET provides ET data from multiple satellite-driven models, and also calculates a single "ensemble value" from the … evapotranspiration gridmet-derived landsat-derived monthly openet water -
OpenET geeSEBAL Monthly Evapotranspiration v2.0
Implementation of geeSEBAL was recently completed within the OpenET framework and an overview of the current geeSEBAL version can be found in Laipelt et al. (2021), which is based on the original algorithms developed by Bastiaanssen et al. (1998). The OpenET geeSEBAL implementation uses land … evapotranspiration gridmet-derived landsat-derived monthly openet water -
OpenET PT-JPL Monthly Evapotranspiration v2.0
Priestley-Taylor Jet Propulsion Laboratory (PT-JPL) The core formulation of the PT-JPL model within the OpenET framework has not changed from the original formulation detailed in Fisher et al. (2008). However, enhancements and updates to model inputs and time integration for PT-JPL were made to take … evapotranspiration gridmet-derived landsat-derived monthly openet water -
OpenET SIMS Monthly Evapotranspiration v2.0
Satellite Irrigation Management Support The NASA Satellite Irrigation Management Support (SIMS) model was originally developed to support satellite mapping of crop coefficients and evapotranspiration (ET) from irrigated lands and to increase access to this data to support use in irrigation scheduling and regional assessment of … evapotranspiration gridmet-derived landsat-derived monthly openet water -
OpenET SSEBop Monthly Evapotranspiration v2.0
Operational Simplified Surface Energy Balance (SSEBop) The Operational Simplified Surface Energy Balance (SSEBop) model by Senay et al. (2013, 2017) is a thermal-based simplified surface energy model for estimating actual ET based on the principles of satellite psychrometry (Senay 2018). The OpenET SSEBop implementation uses … evapotranspiration gridmet-derived landsat-derived monthly openet water -
Landsat Gross Primary Production CONUS
The Landsat Gross Primary Production (GPP) CONUS dataset estimates GPP using Landsat Surface Reflectance for CONUS. GPP is the amount of carbon captured by plants in an ecosystem and is an essential component in the calculations of Net Primary Production (NPP). GPP is calculated using … 16-day conus gpp gridmet-derived landsat mod17 -
Landsat Net Primary Production CONUS
The Landsat Net Primary Production (NPP) CONUS dataset estimates NPP using Landsat Surface Reflectance for CONUS. NPP is the amount of carbon captured by plants in an ecosystem, after accounting for losses due to respiration. NPP is calculated using the MOD17 algorithm (see MOD17 User … conus gridmet-derived landsat mod17 nlcd-derived npp -
MODIS Gross Primary Production CONUS
The MODIS Gross Primary Production (GPP) CONUS dataset estimates GPP using MODIS Surface Reflectance for CONUS. GPP is the amount of carbon captured by plants in an ecosystem and is an essential component in the calculations of Net Primary Production (NPP). GPP is calculated using … 8-day conus gpp gridmet-derived mod09q1 mod17 -
