title: Dataset for the manuscript "Are remote sensing evapotranspiration models reliable 2 across South American ecoregions?" published in WRR

description: <strong>Metadata of ‘<em>Are remote sensing evapotranspiration models reliable across South American ecoregions?</em>’ </strong> This document describes the file formatting and data used to run and evaluate the evapotranspiration models in this study. Because forcing data varies among models, each input file contains a different set of meteorological data placed within a folder named after the corresponding model. <strong>File format and time stamps</strong> Data files are CSV formatted with timestamps in the first column of the file. The following timestamps are used: GLEAM: Year (YYYY); Day of Year (DDD) PT-JPL: Year (YYYY); Month (MM); Day (DD) PM-MOD: Year (YYYY); Month (MM); Day (DD) PM-VI: Date (MM/DD/YYYY) <strong>Missing data</strong> Missing data are reported using ‘NaN’ as a replacement flag. Data for all days in a leap year are reported. <strong>Data format</strong> The column headers Name, Description and Units are adopted used in the data files to describe the following variables:: ETo, Penman-Monteith FAO-56 reference evapotranspiration (mm day<sup>-1</sup>); ETobs, Observed evapotranspiration (mm day<sup>-1</sup>); Rn, Surface Net Radiation (w m<sup>-2</sup>); Rg, Daylight shortwave Incoming Radiation (w m<sup>-2</sup>); Rgs_out, Shortwave Radiation - outgoing (w m<sup>-2</sup>); G, Soil heat flux (w m<sup>-2</sup>); P, Rainfall (mm day<sup>-1</sup>); T, Surface Air Temperature (ºC); Tmax, Maximum Temperature (ºC); Tmin, Minimum Temperature (ºC); Tday, Daytime Temperature (ºC); TminDay, Daytime Minimum Temperature (ºC); TminNight, Nighttime Minimum Temperature (ºC); Patm, Atmospheric Air Pressure (Pa); ea, Actual Vapor Pressure (kPa); es, Saturation Vapor Pressure (kPa); VPD, Vapor Pressure Deficit (kPa); eaDay, Daytime Actual Vapor Pressure (kPa); eaNight, Nighttime Actual Vapor Pressure (kPa); RH, Air Relative Humidity; RHDayTime, Daytime Air Relative Humidity; RHNightTime, Nighttime Air Relative Humidity; LAI, Leaf Area Index (m² m<sup>-</sup>²); SWC, Soil Water Content (mm m<sup>-1</sup>). <strong>Forcing data per model</strong> Each model requires a different set of forcing data, as follows: GLEAM: Rn, P, T, Rgs_out; PT-JPL: Tmax, Rn, RH (or e<sub>a</sub>); PM-MOD: Rg, Tday, TminDay, TminNight, RHDayTime, RHNighttime, eaDay, eaNight; PM-VI: ETo. <strong>Tower sites (IDs) and co-authors/PIs:</strong> SDF: J.
