Cal-Adapt 2.0: Beta Site Displays Annual Averages for Temperature and Precipitation

Roll-out of Cal-Adapt 2.0 is underway! Cal-Adapt 2.0 will showcase higher-resolution data describing projected temperature and precipitation in California, based on a new method (“LOCA”, or Localized Constructed Analogues) that improves descriptions of extreme temperatures and spatial distribution of precipitation, both of which are critical for understanding climate-related risks such as heat waves and inland flooding. These new data also align Cal-Adapt 2.0 with current IPCC scenarios used in its Firth Assessment Report (AR5). In addition to LOCA data at 1/16 degree spatial resolution and daily time steps, Cal-Adapt 2.0 presents users with gridded observed historical data.

A beta site offers a sneak preview of Cal-Adapt 2.0, which is built using an Applications Programming Interface (API) that enables users to build custom tools based on datasets displayed by Cal-Adapt. The beta site currently offers visualizations of projected annual maximum and minimum temperatures, as well as average annual precipitation. Over the next few months, additional visualizations will be launched to describe projections for extreme heat, snow pack, wildfire, sea level rise, and additional perspectives on temperature and precipitation, such as monthly averages. Over the course of 2016, even more enhancements will be launched, including visualizations of data portraying projected and reconstructed historical stream flow at 50+ locations in California, probabilistic sea level rise projections to help decision-makers contend with broad uncertainty, inundation maps portraying flooding due to combined impacts of storms and sea level rise in the Delta, and tools to help clarify the impacts of climate change on California’s energy system.
