Calibration Scale	9999-12-31 00:00:00 - 9999-12-31 23:59:59: NOAA 2003
Instrument(s)	9999-12-31 00:00:00 - 9999-12-31 23:59:59: Preconcentration system:(Air Server/Unity thermal Desorber Markes international). GC 6890 + MS 5973N Agilent Technologies.(Gas chromatography (MS))
Intake Height above ground level	9999-12-31 00:00:00 - 9999-12-31 23:59:59: 2 (m)
Sampling Frequency	weekly
Measurement Calibration	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.
Data Processing	Four measurements on each sample are performed and the mean value and standard deviation are calculated and reported.
Processing for averaging	[Hourly] [Daily] [Monthly] The reported data are the arithmetic mean of the values measured each month.
Original Data Quality Flag	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
Data Quality Flag (Valid/Invalid)	Valid: 1a
Observation Status	Temporarily suspended
Description	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).
Meteorological Data Availability (1: Available)	Wind direction: 1 Wind speed: 1 Relative humidity: 1 Precipitation amount: 0 Air pressure: 1 Air temperature: 1 Dew point temperature: 0 Sea water temperature: 0 Sea surface water temperature: 0 Sea water salinity: 0 Sea surface water salinity: 0
Meteorological Data Description	Meteorological data may remain as first provided, even when greenhouse gas data are updated. The intake height for air sample collection is 10 meters above ground level (55 meters above sea level).
