ETo‐Brazil: A Daily Gridded Reference Evapotranspiration Data Set for Brazil - Repository

Shortname: ETo-Brazil
Longname: Gridded reference evapotranspiration for Brazil based on machine learning - 1-Day 0.1 degree x 0.1 degree
DOI: 10.17632/sstjw74ryh.3
Version: 03
Format: TIFF
Spatial Coverage: -74.0, -34.7, -33.8, 5.3 -- (xmin, xmax, ymin, ymax)
Temporal Coverage: 2000-06-01 to 2020-12-31
File Size: ~0.3 MB per file
Coordinate Reference System: WGS 84 - Geodetic coordinate system for World (EPSG: 4326)

Data Resolution
Spatial: 0.1° x 0.1° (rougly ~10 x 10 km)
Temporal: 1-Day

Highlights:
- The grid cells of the ETo-Brazil match the grid cells from the Global Precipitation Measurement data (position and resolution).
- This dataset's overall root mean square error (RMSE) (using weather stations as observed data) is 0.59 mm/day. This is an improvement in earlier attempts to map ETo using interpolation and geostatistics.

History:
- V4 (2021-06-04): Extended the temporal coverage up to 2020-12-31;
- V3 (2020-07-12):
- Fixed a small problem with the covariates projection. This fixed grid cells positioning and lead to an improvement in performance: RMSE reduced from 0.65 to 0.60 mm/day;
- Extended the temporal coverage up to 2019-12-31;
- V2 (2020-05-21): Masked files for Brazil boundaries only. Reduced file size by ~40%.
- V1 (2020-03-20): First published
