- The Grünloch-Experiment (Lunz am See, Austria)

- Meteorological Field Campaign about temperature inversions in Alpine basins


 

4 February 2004. Today we had to download the temperature data logger (HOBO) before they would run out of disk space.

So we met at 7 AM at the trail head of the Lechnergraben trail.

In the background you can see the wide saddle to Grünloch, wich is also the outflow of the Grünloch cold air pools.

 

Because we didn't know the snow situation at Lechnergraben (canyon), everyone had to wear an avalanche beacon.

 

First barriers at the way to Grünloch.

 

Last day was raining a lot in this region. The weather station at Lunz am See measured 70mm precipitation (2.8 inch). The snow level was at more than 1500m MSL, so a lot of wet snow avalanches went down.

Fortunately there was not so much water in the creeks as we expected, so we had no problems in crossing them.

After 3 hours walking time we arrived at Grünloch. The rain of the last days drew nice pattern into the snow (visible stream lines)

Downloading the data. Exiting moments, did the insulation of the computer unit work?
