A high-precision continuous measurement system for the atmospheric O_2/N_2 ratio at Ny-Alesund, Svalbard and preliminary observational results
With the aim of carrying out detailed monitoring of temporal variations in the atmospheric O_2/N_2 ratio at Ny-Alesund, Svalbard, we have developed a new highprecision continuous measurement system, with a precision of better than ±4.0 per meg, using a fuel-cell O_2 analyzer. Considering the remoten...
