    CoCoRAHS Season #2 Concluded

      Good Morning CoCoRaHS,

      We have officially concluded the second season of CoCoRaHS albedo down here at UNH.

      As I mentioned in my previous post, you may keep collecting data if you still have snow on the ground.

    Nearing the end of Season #2

      The snow is getting shallower by the day, so it is time to start thinking about wrapping up the season. You may conclude your sampling season when all of your snow has been melted for at least three days in a row, or by April 1st, whichever comes first.

      If you still have snow after April 1st and would like to keep sampling, by all means keep doing so (I'm looking at you NH-CS-10, 27.5" as of 03/27/2013). We'll plan on having a wrap-up meeting in early May.

      As always many thanks for a great second season!

      If you're looking for a new Citizen Scientist project to join for the spring, might I suggest Project BudBurst? It's really simple:

      1) Register online at

      (2) Sign up for regular reports (submit a report on the same plant each year) or single reports (submit one report one time for any number of plants.

      (3) Have fun spotting plants bloom this spring!

    Happy Spring Equinox!

      It appears winter just doesn't want to say good bye yet this year. We just received another 12" of snow in Durham. Please keep measuring until the snow disappears. The melt season is the most crucial time of year to keep up the albedo measurements over the rapidly changing snow pack.

    Daylight Savings Time!

      Note that Daylight Savings Time happens this weekend. When you change your clocks this will change the time you make your solar noon measurements.

      For example, today local solar noon occurs at 11:54 AM in Durham, NH.

      Tomorrow, local solar noon will be at 12:54 PM in Durham, NH due to daylight savings time.

      And remember, if you are ever unsure when to measure, you can use the handy NOAA Local Solar Noon Calculator. Be sure to click the 'DST' box for Daylight Savings Time.

      Thanks!! And think spring!
