Method and system for improved snow water equivalent estimates

Abstract

A method for estimating snow water equivalent (SWE), including receiving radar samples of precipitation over a region of interest (ROI), and using microphysics parameters to calculate a weather radar SWE (WRSWE). Using a reference SWE for a location in the ROI, determine a loss function, and perform a minimization process on the loss function to optimize the parameters and optimize a Q value (Q0). Finally, recalculating an optimized WRSWE using the optimized parameters, and multiplying the optimized WRSWE by Q0 to determine a corrected SWE (CSWE) for the location. CSWE may be mapped throughout the ROI by use of actual and extrapolated Q0 values. A system for estimating SWE, including radar samples of precipitation over a ROI, microphysics parameters, an RSWE for a location in the ROI, a graphical user interface, computer memory and a computer processor, wherein the processor is configured to execute instructions to perform the SWE estimation.
