Ruifang Li
325 Broadway
Boulder, CO 80305-3328


Associate Scientist III

Ruifang works mainly on data assimilation and in transferring HRRRv4/RAPv5 into FV3. We install capabilities required for DA in FV3 including latent heat forcing, cloud analysis and execute real-time and retrospective DA-cycling runs of regional FV3 at 12-km and 3-km, I also work on AOD and PM2.5 data assimilation for WildFire project.
