Mid-April snow assessment — Part 2

Following on from yesterday, here are some photographs of the 'ground tile'. These were also taken on the 15th April 2011. As you can see, the snow is starting to clear from the cover. In the first photograph, South is roughly at the left. However, at this time of the year, the direct sunlight is starting to come in from a wide range of angles.


Here's another view of the same tile, but taken from the side (90 degrees to the first photograph).


If you remember that the height of a LOFAR tile is 50cm, you can see that the snow is still that deep in places, mostly due to wind-sweeping. On the downwind side, the snow depth drops away.
