Dual-Pol Observations in NW Environment OLYMPEX Planning Meeting
The OLYMPEX planning meeting in Seattle on January 22, 2015 discussed the contribution of polarimetric S-band radar in rain estimation systems targeted by OLYMPEX. The use of specific differential phase (Kdp) helps in minimizing assumptions about drop size distribution, convective/stratiform distinc

OLYMPEX Airborne Data Analysis for Snowfall Rate-Reflectivity Relationships
Utilizing Citation aircraft data from OLYMPEX, this study focuses on developing relationships between snowfall (rainfall) rate and radar reflectivity across various radar bands. Comparisons are made between in-situ aircraft data and retrieval products from CloudSat, GPM, and TRMM datasets. Results i

Effects of Down-Valley Flow on Precipitation Patterns and Microphysics
Down-valley flow in complex terrain areas like the Alps and British Columbia modifies precipitation patterns through diabatic cooling and melting effects. Observations from the OLYMPEX field campaign show how down-valley flow is influenced by both thermodynamics and pressure gradients, with signific
