One More Sampling Session at the SST

It seems that this was the last complete day that I spent measuring at the GAW Lab and the SST. I discussed the coming days’ schedule with Brad and my samples have to be ready on Sunday night, if they should get on the same plane as myself. That means I will have a pretty tight schedule on Sunday, because I would like to pack the snow samples as late as possible.

Sampling went well and included pit sampling of six layers in a 60 cm pit that I dug. Despite the warm weather there is still quite a bit of snow left – not that surprising, when I measured -12.1 degrees C at the snow-soil interface. On they way up to the road and on some of the slopes, however a lot of the snow is already gone. I also emptied the bio-sampler and put on the MOUDI one more time. Finally I took some of my equipment down to the base for snow-sampling on the weekend. At TGIF I spoke to the SWO and we will be heading out to the BAY site on Sunday. Good – so I will get a second data point there, not much in total, but at least some indication of what is going on down there. I just hope that the wind will be fine, not blowing from the base and so that the truck will be located downwind (I will have to keep it running).
