ICOS/DK Stations

Station nord

Measurement site Station Nord, North East Greenland, is located at
81°6' N, 16°40' W, 25 m ASL.


Tubing to sample air at 4 heights is installed at an 80 meter mast
with inlet in 3.6 m, 20, m, 40 m and 60 m. A PICARRO G2301 is
used to measure CO₂, CH₄ and H₂O. Fluxes of CO₂ and CH₄
(PICARRO) in 60 meter.
