%description
Compute the standard suite of climate indices from daily weather
observations. Provides the canonical 'ETCCDI' 27 (Expert Team on Climate
Change Detection and Indices), the 'ET-SCI' heatwave and cold-wave
families plus the Excess Heat Factor of Nairn and Fawcett (2013), and
agroclimatic, drought, and human-comfort families. Drought indices ('SPI',
'SPEI') accept a choice of distribution (gamma or Pearson III for SPI;
log-logistic or generalised extreme value for SPEI). Reference
evapotranspiration is available via Hargreaves and the FAO-56
Penman-Monteith method (Allen et al. 1998). Percentile-based indices
support the Zhang (2005) in-base bootstrap. Daily inputs are numeric
vectors plus a 'Date' vector; outputs are tidy data frames. Optional
gridded support via 'terra' applies any index over a 'SpatRaster' and
reads 'netCDF' input. No external API calls; pairs with data packages such
as 'readnoaa'. References: Alexander et al. (2006)
