Hydrology Applications




Dr. Ma is a Hydrologist affiliated with Cooperative Institute for Research in the Atmosphere (CIRA) working at the Hydrology Applications Division of NOAA Physical Sciences Laboratory. At NOAA, his work aims to support decision making around critical water resources issues in the United States. More specifically, he is responsible for exploring the value of weather radar in water resources management (e.g., flood protection, storm contamination) through the development of an interface between weather radar system and hydrologic models with a focus on the assimilation of radar observations for hydrological forecasts and end user impact. In addition, his research interests focus on understanding the impact of post-wildfire land/soil conditions on flash floods and debris flow risk in California.
