- Radar quantitative precipitation estimation (QPE) over complex terrain such as the San Francisco Bay Area remains a challenge due to the complex spatial and temporal variability of precipitation microphysics.
- The NEXRAD operational radar network is insufficient to provide accurate, short-term near surface rainfall estimates in the Bay Area for urban hydrometeorological applications. This paper describes the deployment of X-band radar system to augment NEXRAD coverage and aid in monitoring precipitation for local forecasters and water managers as well as to better understand precipitation processes occurring in this region.
- The X-band radar can provide high quality rainfall estimates that perform better than NEXRAD-based operational products. The high resolution rainfall monitoring system based on gap-filling radars in this urban region also provides a host of benefits across different sectors of the economy.
