Log of Dust-on-Snow Events with Wind Rose Images
Click on each date for a wind rose image during the dust event (reduced-size example on right). We have estimated beginning and end times of each event based on observations from Silverton, CO. It is reasonable to assume that our skill at detecting dust-on-snow events has improved over time and that we may have failed to observe very small events during the early years of this work. Additional wind roses can be created using our wind rose tool.

Thanks to our original National Science Foundation research grants for collaborative research (grants ATM-0432327 to Painter at National Snow and Ice Data Center and ATM- 0431955 to Landry at Center for Snow and Avalanche Studies), and to the subsequent support of the Colorado Dust-on-Snow program by Colorado water districts the State of Colorado, the U.S. Bureau of Reclamation, and others, this program has accumulated several seasons of dust-on-snow observations at our Senator Beck Basin Study Area (SBBSA) at Red Mountain Pass, summarized in the table below. It is reasonable to assume that our skill at detecting dust-on-snow events has improved and that we may have failed to observe very small events during the early years of this work. Therefore the table represents an absence of events in grey for the first two years of observation but thereafter indicates an absence of observed events as “0” (zero)
