Interim report of the project
The project has produced an Interim Report summarizing all of its findings during its first two years. These include a number of findings that have contributed to the community of downscaling researchers and resulted in presentations to scientific audiences and practitioners as well as publications.
Sign of Observed California Temperature Trends Depends on Data Set Homogenization: Implications for Weighting and Downscaling
Synopsis: We looked carefully at the observational records of temperature and precipitation over California and found that the entire state has warmed over the 20th Century. Models that project future climate in California need to closely match these observations for their historical simulations.
An Extreme-Preserving Long-Term Gridded Daily Precipitation Dataset for the Conterminous United States
Synopsis: We have not accounted for changes in historical precipitation records and have underestimated extreme precipitation over the CONUS in climate model downscaling workflows.
Identifying and correcting biases in localized downscaling estimates of daily precipitation return values
Synopsis: We have been averaging precipitation into grid boxes and underestimating extreme precipitation over the CONUS in climate model downscaling workflows.
Evaluation of a Reanalysis-Driven Configuration of WRF4 Over the Western United States From 1980 to 2020
Synopsis: We have developed a robust and efficient framework for using WRF to downscale most Earth System Models in CMIP6.
