Colorado Dust-on-Snow Program: SNOTEL Datasets

          CODOS Quick Links

Using the NRCS SNOTEL data, CSAS has assembled datasets presenting Peak SWE and subsequent snowmelt rates at 15 SNOTEL sites distributed throughout Colorado, 11 of which are near a CODOS monitoring site. The remaining 4 SNOTEL sites are in locations between CODOS sites, representing additional terrain.  Water Year 2006-2012 Snotel data were examined since this period spans our efforts to monitor dust-on-snow deposition and its effects on Colorado snowmelt behavior.  Mean values are calculated for annual datasets representing all fifteen sites, but those averages are intended to be merely descriptive of those years, and not predictive of past or future years. The datasets include:

  • Peak SWE
  • Dates of peak SWE
  • Days to 'Snow All Gone' (SAG)
  • Daily SWE loss, adjusted for SWE added after peak
  • Mean temperature (during post-peak SWE period)
  • Maximum 5-Day Moving Average of Daily Loss of SWE
  • Number of Dust-on-Snow events after peak SWE

This workbook contains individual spreadsheets for Water Years 2006-2012 and also includes summaries of all 7 years:

Each of these workbooks contain spreadsheets for each year, including a summary aggregating all years for each site:
