Getting Started

helios is an R package that calculates heating and cooling degrees using high temporal and spatial resolution of climate data and population data. helios currently supports WRF data and ISIMIP-CMIP data, or same format with any of them. For more details:

  • GCAM-Regions Tutorial introduces how to use helios to calculate heating and cooling degree-days for 32 global regions in GCAM.
  • GCAM-USA Tutorial introduces how to use helios to calculate heating and cooling degree-hours for CONUS in GCAM-USA.
