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). 

MAGT (C) -2,5
MAGT_DEPTH (m) 15,0
MAGT_DATE 26.05.2008-25.05.200

 

MEAN ANNUAL GROUND TEMPERATURE AT OR NEAR DEPTH OF ZERO ANNUAL AMPLITUDE (°C) – report  value for most recent year or 12 month interval -2.8°C (MAGT-ZAA)

Depth of zero annual amplitude (or depth of measurement reported above)  (m) 16m

Year or 12 month interval for mean reported above 2005

 

AIR TEMPERATURE AND SNOW COVER THICKNESS/DENSITY MEASUREMENTS AT THE BOREHOLE SITE (indicate frequency of observations): Air temperature: Yes [x ] No [ ]    Snow thickness: Yes[x] No[ ]   Density: Yes [ ] No[x]

Also relative humidity, net radiation, wind speed/direction – one measurement every hour

 

NAME AND LOCATION OF CLOSEST CLIMATE STATION (latitude, longitude, and distance from borehole, km) – provide (if available) mean monthly air temperature and snow depth of reporting interval for mean annual ground temperature

Installed at site Sept. 1999   MAAT approx. -4.5°C. Snow thickness is very low (<0.1m) owing to the exposed setting.
