The State of California has been supporting regional climate change research for more than a decade. These studies have complemented research at the national level and have been designed to inform climate policy deliberations and actions in California. This Research Catalog provides basic information about past and ongoing climate change related studies that state agencies have conducted or commissioned since the early 2000s. The purpose of this catalog is to document California’s research efforts and to facilitate the exchange of information.

Enhances dynamic regional climate models and compares them with observation to discover any biases before these models are used to develop probabilistic climate projections for CA
ATMOSPHERIC INVERSE MODELING METHODS OFFER THE POTENTIAL TO ACCURATELY QUANTIFY CURRENT GHG EMISSIONS AND FUTURE REDUCTIONS, REDUCING UNCERTAINTY IN INVENTORY ESTIMATES. LAWRENCE BERKELEY NATIONAL LABORATORY (LBNL) WILL EMPLOY INVERSE MODELING BY COMPARING MEASURED AND PREDICTED ATMOSPHERIC GHG CONCENTRATIONS IN AN ANALYSIS THAT EXPLICITLY CONSIDERS SOURCES OF ERROR. SPECIFICALLY, LBNL WILL 1) CONTINUE AND EXTEND GHG MEASUREMENTS AT EXISTING LBNL MEASUREMENT SITES, 2) IMPLEMENT GHG MEASUREMENTS AT A NEW SITE THAT SAMPLES AIR REPRESENTATIVE OF THE RIVERSIDE AND SAN BERNADINO REGIONS, AND 3) APPLY AN INVERSE MODELING FRAMEWORK TO ESTIMATE GHG EMISSIONS FROM THE MAJOR EMISSION REGIONS OF CA. THIS FOCUSED RESEARCH WILL ENABLE CARB TO 1) CONTINUE AND INTEGRATE MEASUREMENTS OF THE FULL-SUITE OF GHGS (CO2, METHANE, NITROUS OXIDE, AND HIGH GLOBAL WARMING POTENTIAL GASES) AT THE SUTRO TOWER AND WALNUT GROVE SITES INTO THE CARB NETWORK, 2) EXPAND THE CARB MEASUREMENT NETWORK TO COMPREHENSIVELY SAMPLE GHG EMISSION SOURCES IN THE SOUTH COAST AIR BASIN, AND 3) CONDUCT COMPREHENSIVE INVERSE MODELING TO QUANTIFY CA’S CURRENT GHG EMISSIONS USING THE COMBINED MEASUREMENT ASSETS AVAILABLE FOR CA. THE PRODUCTS WILL BE A RIGOROUSLY DEFENSIBLE ESTIMATE OF ANNUAL TOTAL ANTHROPOGENIC GHG EMISSIONS AND A MEASUREMENT AND MODELING SYSTEM CAPABLE OF CONTINUING THOSE ESTIMATES INTO THE FUTURE.
Research results will link combustion emissions of black carbon (BC) to climate impacts in California through an approach that includes observations, data analysis, and modeling. Specifically, the investigators will: 1- create an integrated observational data set of BC regional properties including time series of concentrations and composition, vertical profiles, mixing state, and deposition on snow; 2- estimate the three-dimensional structure of the radiative forcing of BC and other aerosols; and 3- estimate the impact on climate change and climate feedbacks, using a regional climate model.

Developes and maintains a data set of long-term meteorological and hydrological measurements in CA for climate change studies
This study seeks to monitor the environment in the complex topography over the California region, which requires a denser network of meteorological and hydrological stations than is currently operating.
Measured the amount of black carbon (BC) in rain and snow to estimate the potential effect of BC on the reflectivity of snow. A darker snow melts sooner and faster confounding the climate change signal
