 weekly
 NOAA/CMDL 2003 scale.
Four measurements on each sample are performed and the mean value and standard deviation are calculated and reported.
Sequence of analysis alternates measurements of the primary standard with aliquots of the sample according to the following scheme:

Standard_a
Sample1
sample2
Standard_b
Sample3
Sample4
Standard_c

Bracketing of sample values with standard measurements are used for calibration (i.e. sample1 and sample2 values are calculated referring to a calibration curve obtained form the mean of standard_a and standard_b areas).


The reported values are the arithmetic mean of the 4 measurements (sample1-4) carried out on each flask sample.
 Four measurements on each sample are performed and the mean value and standard deviation are calculated and reported.
 [Hourly]
 [Daily]
 [Monthly] The reported data are the arithmetic mean of the values measured each month.
 A QC flag assignment of "1a" indicates the measurement result is preliminary and has not yet been carefully examined by the PI.The "1a" flag is removed once the quality of the measurement has been determined, and replaced with "C1-C4" flag.

C1: checked value obtained as the arithmetic mean of 4 measurements carried out on each sample.
C2:value obtained as the arithmetic mean of 3 measurements carried out on each sample (one rejected).
C3:value obtained as the arithmetic mean of 3 measurements carried out on each sample (2 rejected).
C4:value obtained from 1 measurement carried out on one sample (3 rejected).


X. : rejected as not representative of background conditions (>3 sigma from a fitted curve)

N. : rejected due to error in sampling or analysis
 Valid: 1a
 Temporarily suspended
 Samples are collected weekly in 6 L stainless steel canisters, whose internal walls are passivated by means of a silcosteel layer.
The canisters are first evacuated and then pressurized to 300 kPa. The samples are dried using a magnesium perchlorate trap.
Mixing molar ratio is determined at the Laboratory in Rome (ENEA-Casaccia).
