For those wondering what the snow condition was like during our site visit, below are photos taken by Rosalyn Stilling (NCAR Digital Engagement Specialist/Science Communications). Please provide credit if these are used in presentations.
We noticed a very thin and delicate veneer of ice coating the surface. You can see the glint of it in the photos. We had full-sun conditions and by the afternoon the snow had turned a bit slushy when walking about. Overall, the snow was crunchy (crystalized) with dirty patches. Us walking about probably added to the dirty snow.
Site C - adding the 1m sonic/irga.
Site UW - Bring the 2.5 m sonic/irga to 2 m.
Below are my photos of the 1 m sonic/irga at site C. We dug a well to keep the sensors unburied. Unfortunately, our movements left large holes in the snow.
