Provides the canonical 'ETCCDI' 27\n(Expert Team on Climate Change Detection and Indices), the\n'ET-SCI' heatwave and cold-wave families plus the Excess Heat\nFactor of Nairn and Fawcett (2013), and agroclimatic, drought,\nand human-comfort families. Drought indices ('SPI', 'SPEI')\naccept a choice of distribution (gamma or Pearson III for SPI;\nlog-logistic or generalised extreme value for SPEI). Reference\nevapotranspiration is available via Hargreaves and the FAO-56\nPenman-Monteith method (Allen et al. 1998). Percentile-based\nindices support the Zhang (2005) in-base bootstrap. Daily\ninputs are numeric vectors plus a 'Date' vector; outputs are\ntidy data frames. Optional gridded support via 'terra' applies\nany index over a 'SpatRaster' and reads 'netCDF' input. No\nexternal API calls; pairs with data packages such as\n'readnoaa'. References: Alexander et al. (2006)\n; Zhang et al. (2011)\n; Zhang et al.
