Colorado Dust-on-Snow Updates

With direct funding support from stakeholders, CODOS monitors the presence/absence of dust layers at 11 mountain pass locations throughout Colorado. With those data, data from nearby Snotel sites, and weather forecasts, CODOS provides its funders with a series of “Update” analyses of how dust-on-snow is likely to influence snowmelt timing and rates during the snowmelt runoff season.

Current funders receive timely updates throughout the snowmelt season. Please contact Chris Landry if your agency/organization is interested in joining the CODOS stakeholders.
