 Reference standard are real air pumped in Luxfer Scott Marrin cylinders and calibrated at MPI-Jena against MPI-Jena cylinders.
Every 15 minutes a sample is analyzed alternating between real air and reference standard in order to correct for short time instrumental drifts. molar fraction is calculated from the ratio of the peak heights and than corrected for non linearity of the detector.

 High flux of real air continuosly flow through the sampling line and every 30 minutes a portion is splitted for 3 minutes to the gas-chromatograph sampling loop.
Environment: Mountain peak with completly free horizon.
No local sources of contamination. No access by road.
Timberline about 300m below the measurement site.
Measurements started on Jan 2007 with a modified version of a commercial RGD2-Trace Analytical analyzer; measurements has stopped on March, 2010, for an electronic failure to the detector MB.
time resolution: 1 measurement every 30 minutes;
sensitivity: +- 10 ppb
detection limit: 100 ppb
measurements range: 1 - 10^3 (100 ppb - 100 ppm)
linearity: regularly checked and corrected up to 700 ppb with primary standards
The air is sampled by a 2m long heated intake at 7 m height above
the ground. The air intake is composed by an external (outside building) steel pipe (internally covered by Teflon) and the internal (inside building) Pyrex pipe.
A Stainless steel sampling line (lenght 10m) connects the air intake with analyzer high flux sampling pump.
