climatrends: Climate Variability Indices for Ecological Modelling

Computes climate indices for the analysis of climate trends and for ecological and crop modelling: temperature and precipitation indices (Aguilar et al. 2005 <doi:10.1029/2005JD006119>), growing degree-days, late spring frost, crop-sensitive heat stress indices (Challinor et al. 2016 <doi:10.1038/nclimate3061>) and reference evapotranspiration. Indices are computed from local data or from daily data fetched from 'NASA POWER' for each site, with start dates and lengths that can differ between sites, as in decentralised on-farm trials.
