CSAS Data: Graphs & Plots

We've prepared the following sets of graphs & plots from our Mountain System Monitoring data. Let us know what else you'd like to see plotted: kbuck@snowstudies.org

Above are our hand-drawn strip charts of selected data from Senator Beck Basin Study Area, which includes Swamp Angel Study Plot (SASP), Senator Beck Study Plot (SBSP), Putney Study Plot (PTSP) and the Senator Beck Stream Gauge (SBSG). Each column contains data from a single calendar day (midnight to midnight). The data used to draw these charts is also available in spreadsheet and csv formats. Scales are shown at the far left edge of the chart. The following Key describes the elements of chart (from top of chart to bottom): 

  1. Vertical blue bars show precipitation (snow and rain) measured at SASP. Each box represents 5mm of water.  “S#” above some bars indicate a numbered winter storm.
  2. The continuous red line depicts the maximum height of snow at SASP. Each box represents 10 cm.
  3. The continuous green line depicts the maximum height of snow at SBSP. Each box represents 10 cm.
  4. The black triangles show wind speed at PTSP in meters/second. The base of the triangle is the average (resultant) wind speed. The peak of the triangle shows the peak gust for the day. Each box represents 4 meters/second.
  5. The black pie slices depict mean wind direction, +/- 1 standard deviation.
  6. The red horizontal bars show max and min temps at SASP. Each box represents 5° C
  7. The green horizontal bars show max and min temps at SASP. Each box represents 5° C
  8. The orange outlined columns show the 24-hour average of incoming short wave radiation at SBSP. Each box represents 50 watts/m2
  9. The continuous blue line shows stream flow at SBSG. Each box represents 5 cubic feet per second (cfs).  SBSG is shut down during winter months.
  10. Notes below the graph represent visits to the study plots, formal snow profiles and dust-on-snow events (D#).
  11. Day of week, day of year, and calendar day are shown in the lower three rows.
  12. Summary data at the bottom of the chart present monthly and cumulative Water Year precipitation totals.  Water Year data begin October 1.
