Projected peak instantaneous rate of green-up date and spring scale across Wyoming from 2000 to 2099

These data represent projections of peak instantaneous rate of green-up date (PIRGd) and spring scale across Wyoming from 2000-2099. Annual data is provided in gridded time series at approximately 4 km spatial resolution. Projections were generated by applying linear mixed models to contemporary remote sensing data, and applying model parameters to future climate projection data from the MACA dataset. Projections were generated for 5 global climate models (GCMs) and 2 representative concentration pathway (RCP) scenarios: RCP 4.5 and RCP 8.5. Data starting in 2000 are provided to help assess accuracy of model projections against contemporary datasets, and provide a platform for comparison to projections for future years. These data were used to assess future changes to forage phenology greenscapes along mule deer migration routes in Wyoming, and are available to assess the impacts of future climate on a wide variety of ecological processes.
