Station nord

Measurement site Station Nord, North East Greenland, is located at
°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.
