epwshiftr: Create future EnergyPlus Weather files using CMIP6 data

Query, download climate change projection data from the CMIP6 (Coupled Model Intercomparison Project Phase 6) project in the ESGF (Earth System Grid Federation) platform, and create future EnergyPlus Weather (EPW) files adjusted from climate changes using data from Global Climate Models (GCM).

Package options

• epwshiftr.verbose: If TRUE, more detailed message will be printed. Default: FALSE.

• epwshiftr.threshold_alpha: the threshold of the absolute value for alpha, i.e. monthly-mean fractional change, when performing morphing operations. The default value is set to 3. If the morphing methods are set "stretch" or "combined", and the absolute alpha exceeds the threshold value, warnings are issued and the morphing method fallbacks to "shift" to avoid unrealistic morphed values.

• epwshiftr.dir: The directory to store package data, including CMIP6 model output file index and etc. If not set, the current user data directory will be used.
