Order reference gases
To ensure compatibility of of the ICOS observations with data from other global monitoring networks, the measurements need to be traceable to the respective WMO calibration scales. The CAL is responsible for providing real air reference gas standards for ICOS atmospheric observations. Calibration is done using a set of WMO laboratory standards.
Bottle specs:
- diameter: 204 mm
- height (without gas valve): 960 mm
- gas valve connection: DIN14
| 1. | Contact the CAL lab in advance | Please notify the CAL lab via icos-standards@bgc-jena.mpg.de (cc to tsteinhoff@geomar.de) at least two months in advance if you want to order reference gas standards. Please note that the bottles are for the Ocean network. Keep in mind that the bottles that are in use need to be sent back with at least 10 bar, so prepare the gas order in advance. |

| 2. | Provide requested composition list | For submitting the list of requested mole fractions, please use the following Excel template: Order form -reference gases. |

| 3. | Bottles will be sent to you | Once the gases are prepared and calibrated the gas bottles will be sent to the address you specified in the ordering form. The paper work for transportation of dangerous goods will be prepared by the CAL lab. Infomation the shipper needs: 3 bottles are packed on a palette: 120 x 80 x 35 cm, weight ca. 150 kg.
The shipping of the bottles is organized by the sender, which means CAL is taking care of getting the bollles to the stations, But the stations need to take care of sending them back. |
| ||
| 4. | Send empty bottles back | Once the bottles are exchanged, please send the bottles back. Make sure the bottles have at least 10 bar. The shipping of the bottles is organized by the sender, which means CAL is taking care of getting the bollles to the stations, But the stations need to take care of sending them back. |
| The calibrated values will be sent to you and posted below. |
