[from 2012 onward] : To minimize the influence of temperature on the measurements a specific software was designed and used to control the zero calibration, forcing the instrument to execute this calibration every 15 minutes. The zero air necessary for the zero calibration is obtained using a steel tube containing Sofnocat 423. Due to the switching in the instrument internal valves during the zero cycle, the ambient air is forced to pass through Sofnocat ©. The zero air is then injected in the cell for 15 minutes and only the final 5 minutes are averaged to produce the zero value that is the applied to the instrument using our self-built software. The span calibration is performed once a day, starting at 00:30 AM and ending at 00:45 AM. The span value is 500 nmol/mol and this concentration is obtained from the dilution of a 10 ppm CO standard cylinder (CO synthetic air, Messer Switzerland, 2% (k=2) uncertainty) with zero air produced by the zero air unit, which is constituted by carbonate cylinder filled with silica gel (to dry the ambient air) and a steel tube containing Sofnocat© 423. The standard and zero air flows are regulated using two Mass Flow Controller (MFC) (Producer: Brook Instrument Ltd) with different operative range: the one regulating zero air flow works between 0 and 5000 l/min, while the one regulating the standard flow works between 0 and 500 l/min. Two valves electronically controlled are installed before the two MFCs, so that the system could be completely controlled in the case of failures; moreover, in this way, the two MFCs (as are the valves) are normally closed and are opened only when there is the need for the span calibration. This increase the stability of the MFCs calibration as well as the MCF life time. 10 ppm CO standards produced by esser Switzerland with 2% (k=2) uncertainty. [from 2007 to 2010] : 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 reference standard are real air pumped in Luxfer Scott Marrin cylinders and calibrated at MPI-Jena against NOAA cylinders. |
|||||||
| [from 2012 onward] : Row (1-min) data from the monitoring device are acquired every minute and processed to 1-hour mean values. Data is evaluated by the station staff using Excel (visual inspection, consistency checks using additional parameter such as zero/span checks, meteorological data, and statistical checks) | |||||||
|
[Hourly] [from 2012 onward] : Hourly data are obtained averaging 1 minutes mean O3 values [Daily] [from 2012 onward] : Daily data are obtained by averaging hourly data [from 2007 to 2010] : The average data were calculated by WDCGG. [Monthly] [from 2012 onward] : Monthly data are obtained by averaging daily data [from 2007 to 2010] : The average data were calculated by WDCGG. |

[from 2012 onward] : Contact person : Paolo Cristofanelli Scientific Aim : Investigation of background troposphere conditions. Investigation of regional and long-range pollution. Investigation of stratospheric intrusion events. Model validations. Near-real time data delivery. Thermo Scientific TEI 48C-TL #0517111935 Instruments performance are available on http://gaw.empa.ch/audits/CMN_2012.pdf [from 2007 to 2010] : Contact person : Jgor Arduini Principal Investigator : Michela Maione Sampling Environment : Environment: Mountain peak with completly free horizon. No local sources of contamination. No access by road. Timberline about 300m below the measurement site. The air is sampled by a 2m long heated intake at 7m 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. Each data submitted represent a real acquired concentration point, none of the post-acquisition averageing operation has been done. The precision of the measurements is then reported in the data file (REM column) as the relative standard deviation (expressed in percentage) of the repeated measure of the working standard performed in the same day of each real sample analysis (and is generally calculated over 48 working standard runs per day). Description of Instruments : time resolution: 1 measurement every 30 minutes; sensitivity: +- 1 ppb detection limit: 10 ppb measurements range: 1 - 10^3 (10 ppb - 10 ppm) measurements started on Jan 2007 with a modified version of a commercial RGD2-Trace Analytical analyzer; system has stopped working on March 2010 due to an electronic failure to the detector MB. |
