get_ensemble_temp: Download ensemble temperature data

In rWBclimate: A package for accessing World Bank climate data

Description

Function wraps get_ensemble_climate_data() and returns precipitation by basin or country in mm. Output is the 10th 50th and 90th percentile for all gcm's for the a1 and b2 scenarios.

Usage

get_ensemble_temp(locator, type, start, end)

Arguments

locator	A vector of either watershed basin ID's from http://data.worldbank.org/sites/default/files/climate_data_api_basins.pdf It can be just a single basin id, or a vector of ids. ids should be strings.
type	the type of data to retrieve, must be "mavg" for monthly averages, "annualavg" for annual averages, "manom" for monthly anomaly, and "annualanom" for annual anomaly.
start	the start year to gather data for.
end	the end year to gather data to.

Details

start and end year can be any years, but all years will be coerced into periods outlined by the API (http://data.worldbank.org/developers/climate -data-api) anomaly periods are only valid for future scenarios and based on a reference period of 1969 - 1999, see API for full details.

Value

a dataframe with precipitation predictions in mm for all scenarios, gcms, for each time period.

Examples

## Not run: 
# Get data for 2 basins, annual average precipitation for all valid time periods
# then subset them, and plot
temp_dat <- get_ensemble_temp(c("2","231"),"annualavg",1900,3000)
temp_dat <- subset(temp_dat,temp_dat$scenario!="b1")
temp_dat$uniqueGroup <- paste(temp_dat$percentile,temp_dat$locator,sep="-")
ggplot(temp_dat,aes(x=fromYear,y=annualVal,group=uniqueGroup,colour=as.factor(locator),
linetype=as.factor(percentile)))+geom_path()

### Get data for 2 countries with monthly precipitation values
temp_dat <- get_ensemble_temp(c("USA","BRA"),"mavg",2020,2030)
temp_dat <- subset(temp_dat,temp_dat$scenario!="b1")
temp_dat$uniqueGroup <- paste(temp_dat$percentile,temp_dat$locator,sep="-")
ggplot(temp_dat,aes(x=as.factor(month),y=monthVals,group=uniqueGroup,
colour=locator))+geom_path()

## End(Not run)
