Objective(s): The only feasible way to accurately estimate the amount of water available from snow (i.e., snow water equivalent) is using remote sensing techniques. The objective of this project is to develop an algorithm by using an analytical technique (stepwise multiple regression) to convert passive microwave data to snow data.

Project Description: Given the vast size of the N.W.T., it is very difficult to accurately measure the amount of water that is made available from snow (called snow water equivalents or SWE). A variety of agencies have collected data from climate stations and satellites and this data can be used to estimate SWE. This study will involve taking measurements of snow on the ground and comparing these measurements to those predicted using satellite data.
