Highlights

Climate Assessments

• Co-author on NOAA Technical Report TR-144 “Regional Surface Climate Conditions in CMIP3 and CMIP5 for the United States: Differences, Similarities, and Implications for the U.S. National Climate Assessment,” comparing CMIP3 and CMIP5 simulations, in support of the National Climate Assessment.
• Served as co-coordinator for first-ever U.S. State Climate Summary project, detailing climate change projections for each state. Additionally, co-authored content, developed figures, and assisted with editing and review processes.
• Processed the Localized Constructed Analogs (LOCA) data set in support of the upcoming Climate Science Special Report and the Fourth National Climate Assessment. This is a new statistically-downscaled daily data set based on CMIP5 simulations at 1/16th-degree spatial resolution for the conterminous United States. An initial set of 23 derived climate variables have been calculated with additional variables in progress.

From NOAA NESDIS TR144: Projected change in seasonal mean temperature (°F) for the contiguous United States, for 2041–2070 with respect to the reference period of 1971–2000. These are multi-model means using CMIP3 SRES A2 (left column), and CMIP5 RCP8.5 (right column). Color with hatching (category 3) indicates that more than 50% of the models show a statistically significant change, and more than 67% agree on the sign of the change.
