Collection Overview: This lidar dataset was collected as part of an NCALM Seed grant for Sarah Newcomb at Idaho State University. This dataset was collected to investigate the link between snowpack heterogeneity and subsurface storage and transmissivity in the rain-snow transition zone. The study area is located east of Eugene, Oregon and covers approximately 63 km2.Publications associated with this dataset can be found at NCALM's Data Tracking Center
