{"id":501,"name":"Janssonhaugen P10","description":"

The Norwegian PACE boreholes (Janssonhaugen Svalbard and Juvvasshøe southern Mainland Norway) are taken care of by Dr. Ketil Isaksen, so also for the coming years. He serves the dataloggers and collects the data.  The data are stored at the Norwegian Meteorological Institute (met.no). ​
