M. Exposito-Alonso (2017) rbioclim: Improved getData function from the raster R package to interact with past, present and future climate data from worldclim.org. github.com/MoisesExpositoAlonso/rbioclim
For bugs or questions, send an email to: firstname.lastname@example.org
The motivation of this package is to have a rapid access to all time layers available at worldclim.org (needed it for my analyses).
The package includes an improved getData function from the rater package that not only allows the tipical import of present data or IPCC5 daata (2050 & 2070 future), but also the last glacial maxima and mid-holocene datasets (which to my knowledge cannot be downloaded throught the getData function of package raster). It also includes several wrapper functions to download all available datasets at worldclim with a single command.
library(raster) devtools::install_github("MoisesExpositoAlonso/rbioclim") # change exp to master when branches are merted library(rbioclim) bioclim = recursive.getData(times="all") # by default resolution 2.5m and the 19 bioclim variables. (but can be changed)
# Example how to extract the current climate. (Layers have the same name as the zip file but without the .zip) currentclimate<-bioclim[["pres"]] # Or last glaciation: lastglaciation<-bioclim[["lgm"]] # Or for projections under rpc 6.0 to the year 2050: cc602050<-bioclim[["CC6050"]] # And you can plot it plot(currentclimate[["bio1"]]) plot(lastglaciation[["bio1"]]) plot(currentclimate[["bio1"]]- lastglaciation[["bio1"]] ) # the increase in annual temperature
pres = current climatic data, average 1960-1990. lgm = Last Glacial Maximum data (22,000 years ago) from global climate model mid = Mid Holocene data (6,000 years ago) from global climate model CC2650 = 2050 climate from glocal climate model from 5th IPCC. scennario rcp 2.6 CC2670 = 2070 climate from glocal climate model from 5th IPCC. scennario rcp 2.6 CC4550 = 2050 climate from glocal climate model from 5th IPCC. scennario rcp 4.5 CC4570 = 2070 climate from glocal climate model from 5th IPCC. scennario rcp 4.5 CC6050 = 2050 climate from glocal climate model from 5th IPCC. scennario rcp 6.0 CC6070 = 2070 climate from glocal climate model from 5th IPCC. scennario rcp 6.0 CC8550 = 2050 climate from glocal climate model from 5th IPCC. scennario rcp 8.5 CC8570 = 2070 climate from glocal climate model from 5th IPCC. scennario rcp 8.5
BIO1 = Annual Mean Temperature BIO2 = Mean Diurnal Range (Mean of monthly (max temp - min temp)) BIO3 = Isothermality (BIO2/BIO7) (* 100) BIO4 = Temperature Seasonality (standard deviation *100) 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
