KAIRA), the polystyrene frames to house the High-Band Array (HBA) elements, had to be tested for the winter durability. This took place during the winter 2010/2011 at the final KAIRA site, and it is documented on the KAIRA blog beginning with the post "Preparation Work" of 18th October 2010. The entire sequence of blog posts related to the winter test is available under the tag "test tiles".
Mavericks operating system, we found that the excellent aerial imagery of the Kilpisjärvi area clearly shows both test tiles. We do not know when the photo was taken, but the tiles were deployed between mid October 2010 and mid May 2011.
The first photo above shows the general area with the customs station in the south and the KAIRA site north-north-west of it. The second image shows the KAIRA site with both HBA winter test tiles.
