This dataset contains 30-year rolling
averages of annual average minimum and maximum temperatures across all four
models and two greenhouse gas (RCP) scenarios in the four model ensemble. The year identified for a 30 year rolling average is the
mid-point of the 30-year average. eg. The year 2050 includes the values from
2036 to 2065.
The downscaling and selection of models for inclusion in ten
and four model ensembles is described in Pierce
et al. 2018, but summarized here. Thirty two global climate models (GCMs)
were identified to meet the modeling requirements. From those, ten that closely
simulate California’s climate were selected for additional analysis (Table
1, Pierce et al. 2018) and to form a ten model ensemble. From the ten model
ensemble, four models, forming a four model ensemble, were identified to
provide coverage of the range of potential climate outcomes in California. The models in the four model ensemble and
their general climate projection for California are:
HadGEM2-ES (warm/dry),CanESM2 (average),CNRM-CM5 (cooler/wetter),and MIROC5 the model least like the others to
improve coverage of the range of outcomes.
These data were downloaded from Cal-Adapt and prepared for
use within CA Nature by California Natural Resource Agency and ESRI staff.
