It is just amazing how much preparations are needed right before the field work can take place! Iceland will be the first place for us to start this winter-season’s field work. But, we did start a new measurement setup for BC deposition in snow here in Helsinki Kumpula this week, too, at the SMEARIII station, https://www.atm.helsinki.fi/SMEAR/index.php/smear-iii, and it was by a fortunate co-incidence that I started talking with my colleaque Mika Vestenius in the lunch table and thanks to him here we are!
This week, one week before going to field and working on the impurities on snow and water, preparing for field work means pre-burning sample filters, collecting together all the laboratory stuff needed, and planning more detailed about the sampling and the program during the visit… and there will be a lot of going on during the visit, but about that you can read more later in my separate BLACK-blog’s posting on Iceland visit.
So, this week I have pre-burned filters at 800 degrees Celsius for 4 hours! From that, I took an image to show you what it means in practice. Here you go:
In addition, here in Finland many Finns have been occupied with snow and ice although not related to field work preparations. We really have a lot of snow in the capital area of Helsinki this year! And many of us have enjoyed skiing, and clearing snow, too… but now back to sampling…
Why do we need filters in the field work?
Filters are needed after the snow or water sample has been collected and snow melted, the water sample is filtered using a filtration system. The filters look like this:

How to prepare to Iceland in February?
My Icelandic host Hanna María Kristjánsdóttir,Director of the Sudurnes Science and Learning Center, Iceland, has warmly welcomed me and confirmed the stay. Many thanks! Can not wait to meet you all there in Iceland!
In Iceland, the winter weather can be very windy and snowy, depending on the location you are. And it can even happen in Reykjavik, as it was the case on 26 Feb. 2017.
About the new record of 51 cm of snow in Reykjavik on 26 Febr 2017
It really was a fortunate co-incident in 2017, that I was part of an international snow measurement campaign (planned way in advance!) in Reykjavik at the time of this record event. The new February snow depth record measured for Reyjavik was 51 cm. This caused a lot of trouble for the traffic. For us it meant that we had excellent conditions for our international comparison of snow depth and snow water equivalent measurement devices. We were researchers from 10 European countries and USA.
Unexpected wintertime packing list includes a swimming suit for Iceland in February
Nevertheless, after the snowy and windy winter-time field work you will have use for a bathing suit to visit an outdoor hot spring or a swimming pool! An amazing thing to do on a winter day, and possible also in February! It is a must at least once during one winter time snowy field work period!
