 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;
reference standard (local working standard) is regolarly checked against NOAA cylinders
 reported data are single point, no average is computed; data validation is evaluated by checking the correct instrumental operation, the spread of the repeated working standard analysis; in case of anomalies, real data are flagged for a deep check and -eventually- removed form the final dataset. results from target cylinder is used to check for long term stability of the whole set up and eventually correct or remove suspect data.
 0= background data;
1=data possibly affected by local pollution;
2=calibration or invalid data.

 Temporarily suspended
 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 the high flux sampling pump in front of the sampling loop of the analyzer; a cracking check valve is installed downstream the pump to ensure a sligthly overpressure inside the sampling loop and discharge the excess of flow to vent.
