An Investigation of NEXRAD-Based Quantitative Precipitation Estimates in Alaska

Nelson, B. R., Prat, O. P., & Leeper, R. D. (2021, August 12). Remote Sensing, Vol. 8.

By: B. Nelson*, O. Prat n & R. Leeper n

author keywords: NEXRAD; Alaska; precipitation
topics (OpenAlex): Precipitation Measurement and Analysis; Meteorological Phenomena and Simulations; Cryospheric studies and observations
TL;DR: National Weather Service precipitation products that are produced from the seven NEXRAD radar sites in Alaska are investigated and the DPA data shows somewhat better performance in the mixed precipitation phase, which suggests that the NWS Precipitation Processing Subsystem (PPS) is tuned to the climatology as it relates to precipitation in Alaska.
