Unified Climate Indices for Temperature, Precipitation, and Drought R package climatekit version 0.1.0 Compute 35+ standard climate indices from daily weather observations. Includes temperature indices (frost days, ice days, growing degree days), precipitation indices (dry spells, heavy precipitation, intensity), drought indices (Standardized Precipitation Index, Standardized Precipitation-Evapotranspiration Index), agroclimatic indices (Huglin, Winkler, Branas), and comfort indices (wind chill, heat index, humidex, fire danger). All functions accept vectors of observations with dates and return tidy data frames with metadata. Implements the 'ET-SCI' Expert Team on Sector-specific Climate Indices definitions where applicable. No external API calls; pairs with data packages such as 'readnoaa' for acquisition.
