The ACRG has developed a wide range of instrumentation to measure a wide variety of gases, including the full range of Montreal (ozone-depleting) and Kyoto Protocol (global warming) gases. This instrumentation has subsequently been adopted by the entire Advanced Global Atmospheric Gases Experiment (AGAGE) network.

In addition to instruments developed in-house, the ACRG utilises a range of commercially available instruments at its various UK-based measurement sites. The group is engaged in the ongoing development of novel instrumentation for the detection of species including highly reactive Criegee intermediates and isotopes such as carbon-14.


This unique instrument was partly developed here in Bristol for use in the AGAGE (Atmospheric Global Gases Experiment) programme.


The original system we used for trapping and analysing trace gas species in the atmosphere.

Mobile Lab

The mobile lab at Tacolneston, Norfolk, as part of the DECC network.

CRDS Picarro

We have a number of these instruments in the field, one at each of our tall-tower sites.

CRDS Los Gatos Research

We recently took delivery of a Los Gatos Research Analyser for measuring CO and N2O.
