Fresh snow!

Lab Note #13
Jan 31, 2014

It snowed about 4 cm today. It wasn't as much as we had hoped for, but we'll take what we can get. The image below is of a snowpit that Maria dug today.

You can see the slightly brownish color of the top layer of the old snow below the new, fresh snow that fell today. The brown color is from the dust that deposited to the snow surface since the last snowfall (in late December). It will be interesting to see what the surface ozone concentrations are once the clouds are gone and the sun is back. Stay tuned!
