BIOCLIM Description: Bioclim are a series of global climate layers, that have been designed to better support biological studies. Abstract: Bioclimatic variables are derived from the monthly temperature and rainfall values in order to generate more biologically meaningful variables. These are often used in ecological niche modeling (e.g., BIOCLIM, GARP). The bioclimatic variables represent annual trends (e.g., mean annual temperature, annual precipitation) seasonality (e.g., annual range in temperature and precipitation) and extreme or limiting environmental factors (e.g., temperature of the coldest and warmest month, and precipitation of the wet and dry quarters). A quarter is a period of three months (1/4 of the year). WorldClim Author(s):Hijmans, R.J., S.E. Cameron, J.L. Parra, P.G. Jones and A.
