ICOS ATC Mobile Laboratory is one of the units of the ICOS RI Atmospheric Thematic Centre. The main task is to conduct quality control (QC) by parallel measurements at atmospheric stations (AS). Aim is to improve measurement compatibility and development of competent quality assurance (QA) of the ICOS atmospheric station network that ensures credibility of the measurements. Mobile Lab is hosted by the Finnish Meteorological Institute in Helsinki.
Mobile Lab has a van, which is equipped with state-of the-art analysers and standard gases, which are traceable to World Meteorological Organization Central Calibration Laboratory and ICOS Central Analytical Laboratory. Atmospheric Station visit lasts 1-2 months. During the visit standard gases of the station are cross-checked and parallel monitoring of ambient air are conducted to validate quality of the greenhouse gas monitoring of the station.

Hover over the site to know its name. Grey sites are labeled but did not undergo an audit. Green sites underwent an audit from the Mobile Lab. Red circles indicates a WMO audit. Pink sites are not yet labeled. Reports of the audits can be found on Webobs by typing 'Audit MobileLab' or 'Audit WMO' in the search bar (the reports are attached to a maintenance event created for the audit dates) or from the Events page of a site, using the quick search bar over the right period.
