    2014 Winter Olympic Games Science Video Series: Science of Snow episode

      Just came across this great video series produced by the National Science Foundation and NBC exhibiting the science and engineering behind the 2014 Winter Olympic Games. More episodes on various winter sports here. Enjoy!

    Made it to Colorado!

    Tube #'s and Station ID mismatches

      Greetings Albedo Observers!

      The minute I leave the state of New Hampshire, the snow falls like crazy. The second I return it changes to rain. Happy to see so many measurements coming in from across the state, keep up the great work!

      I also received word that there may be some mismatches with tube #'s and station id's in the web data entry form. We hope we have addressed all of them. If you are still having issues, please email me at and we'll sort it out.

      Happy Holidays!

    Remember to enter snow-free values, too

      The snow season is off to a slow start in NH. Please be sure to also enter snow-free albedo values for your site. In the comments section, please enter a brief description of the surface (e.g., dead grass, soil, dead leaves, etc).

      I've been measuring albedo out at the pasture at Thompson Farm and snow-free albedo has been between 0.22-0.27. The values this winter thus far are higher than my average snow-free value from last winter (0.17) when the pasture had been re-tilled and was mostly dark soil. Over the summer, the pasture grass grew back, increasing the snow-free albedo as the dark soil was covered up by now senesced pasture grass.

      I'll do my snow dance this weekend if you all do yours!
