Local Scale Snow Measurements & Analysis at LSOS Site

Explore in-depth snow measurements and analysis conducted at the LSOS site by researchers Janet Hardy, Tim Link, and Richard Essery. Detailed findings from various observation points including dense pine, open pine, and clearing areas are presented. The snow pit measurements carried out from 2002 to 2003, including snow depth surveys during IOPs, offer valuable insights. Discover the significance of snow depth transects, SWE transects, and the subsequent model development and validation based on the data collected. Gain insights into potential applications and the scaling of processes, measurements, and models for high-resolution snow data at LSOS.
