agroclim (version 0.1.0)

Climatic Indices for Agriculture

Description

Collection of functions to compute agroclimatic indices useful to zoning areas based on climatic variables and to evaluate the importance of temperature and precipitation for individual crops, or in general for agricultural lands. Some of the indices are adapted from Gladstones (1992, ISBN:1875130128); Trnka et al. (2014) ; Wrinkler et al. (1974, ISBN:9780520025912); Jones et al. (2010) ; Huglin (1978) .
