=======================================
Get global climate data from Worldclim
=======================================

|

**What it does**

This tool retrieve global climate data from Wordclim using the R raster package.

The climatic data available are : 

  * Minimum temperature (°C x10)

  * Maximum temperature (°C x10)

  * Precipitation (mm)

  * Bioclimatic variables :
    
    * BIO1 = Annual Mean Temperature

    * BIO2 = Mean Diurnal Range (Mean of monthly (max temp - min temp))

    * BIO3 = Isothermality (BIO2/BIO7) (x 100)

    * BIO4 = Temperature Seasonality (standard deviation x100)

    * BIO5 = Max Temperature of Warmest Month

    * BIO6 = Min Temperature of Coldest Month

    * BIO7 = Temperature Annual Range (BIO5-BIO6)

    * BIO8 = Mean Temperature of Wettest Quarter

    * BIO9 = Mean Temperature of Driest Quarter

    * BIO10 = Mean Temperature of Warmest Quarter

    * BIO11 = Mean Temperature of Coldest Quarter

    * BIO12 = Annual Precipitation

    * BIO13 = Precipitation of Wettest Month

    * BIO14 = Precipitation of Driest Month

    * BIO15 = Precipitation Seasonality (Coefficient of Variation)

    * BIO16 = Precipitation of Wettest Quarter

    * BIO17 = Precipitation of Driest Quarter

    * BIO18 = Precipitation of Warmest Quarter

    * BIO19 = Precipitation of Coldest Quarter

|

**How to use it**

Simply select the variable to return and the resolution : 2.5, 5 or 10 minutes of a degree.

Available output format are : netcdf and grd (Native raster package format).
