Estimating Climate Stability from Climate Model Data.

climateStability

The goal of climateStability is to provide a simple set of R-based tools to generate climate stability estimates based on time slices of climate data.

Installation

You can install climateStability from github with:

# install.packages("devtools")
devtools::install_github("hannahlowens/climateStability")

Example

This is a basic example which shows you how to calculate climate stability using time-slice datasets for two variables:

# First, calculate deviation through time using even time slices
precipDeviation <- deviationThroughTime(variableDirectory = "YOUR_DIRECTORY/precipitationFiles/",
                                        timeSlicePeriod = 1000, fileExtension = "asc");
temperatureDeviation <- deviationThroughTime(variableDirectory = "YOUR_DIRECTORY/temperatureFiles/",
                                             timeSlicePeriod = 1000, fileExtension = "asc");

# Next, calculate stability for each variable (the inverse of deviation, scaled to between 0 and 1)
precipInvDev <- stabilityCalc(precipDeviation);
tempInvDev <- stabilityCalc(temperatureDeviation);

# Finally, multiply them together and rescale to estimate relative climate stability
climateStability <- rescale0to1(precipStability * tempStability)
