These indices are\ncalculated using a reference data source. The functions verify\nif the indices' estimates meet the assumption of normality and\nhow well NASA POWER estimates represent real-world data.\nIndices are calculated in a routine mode. Potential\nevapotranspiration amounts and the difference between rainfall\nand potential evapotranspiration are also calculated. The\nfunctions adopt a basic time scale that splits each month into\nfour periods. Days 1 to 7, days 8 to 14, days 15 to 21, and\ndays 22 to 28, 29, 30, or 31, where 'TS=4' corresponds to a\n1-month length moving window (calculated 4 times per month) and\n'TS=48' corresponds to a 12-month length moving window\n(calculated 4 times per month).", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "LazyData": "true", "RoxygenNote": "7.3.2", "URL": "https://github.com/gabrielblain/PowerSDI", "BugReports": "https://github.com/gabrielblain/PowerSDI/issues", "Config/testthat/edition": "3", "Config/testthat/parallel": "true", "VignetteBuilder": "knitr", "Language": "en-GB", "Config/pak/sysreqs": "libssl-dev libx11-dev", "Repository": "https://gabrielblain.r-universe.dev", "Date/Publication": "2024-07-23 11:43:18 UTC", "RemoteUrl": "https://github.com/gabrielblain/powersdi", "RemoteRef": "HEAD", "RemoteSha": "10f64a351cb39f51b5f885b9f959a35a242c4586", "NeedsCompilation": "no", "Packaged": { "Date": "2026-07-15 07:38:20 UTC", "User": "root" }, "Author": "Gabriel Constantino Blain [aut, cre] (ORCID:\n),\nGraciela R.
