Deconvolving Snow Cover and Snowfall Passive Microwave Signals

This research focuses on deconvolving snow cover and snowfall passive microwave signals using GPM data. The study employs a data-driven approach to estimate snowfall using a nested K-nearest algorithm and observed irregularities. By analyzing variations in brightness temperatures (Tbs) over snow-cov
