Results are shown as an interactive time-series chart and can be exported to CSV. Hargreaves is the first supported method \u2014 more evapotranspiration methods are planned.", "homepage": "https://github.com/iliasmachairas/Evapotranspiration-Calculator", "repository": "https://github.com/iliasmachairas/Evapotranspiration-Calculator", "tracker": "https://github.com/iliasmachairas/Evapotranspiration-Calculator/issues", "author": "Ilias Machairas", "tags": ["evapotranspiration", "hargreaves", "era5", "cds", "climate", "hydrology", "et0"], "downloads": 15, "latest_version": "0.0.4", "versions": [{"version": "0.0.4", "experimental": true, "qgis_min": "3.22.0", "qgis_max": "3.99.0", "downloads": 15, "uploaded_by": "iliasmachairas", "upload_datetime": "2026-09-08T17:45:19.062443"}]}
