Ozone (3m)

Model 49C Photometric Analyser, a UV absorption technique with an accuracy of �1 ppbV.

cv-tei-o3

CO

Vacuum ultraviolet fluorescence CO analyser (Aerolaser 5001). It is designed for fast response measurements and has a detection limit of <1 ppbv.

cv-aerolaser-co

NOxy

Air Quality Design NOxy instrument is a single channel, chemiluminescence NO detector with a photolytic NO2 converter (diode based blue light converter (BLC) � Droplet Measurement Technologies) and a Molybdenum catalyst NOy converter (Thermo Electron Industries). The detection limits for a 10 minute data cycle are ~3 pptV, 6pptV, 3pptV for NO, NO2 and NOY respectively.

cv-noxy

Ozone (10m)

Ozone (10m):-Thermo Model 202 UV Absorption manufactured by 2B Technologies. This instrument also has an accuracy of � 1 ppbV.

cv-2b-o3

VOC

Dual channel gas chromatograph with dual flame ionisation detection (GC-FID) measures C2-C8 Non-methane hydrocarbons and also C2-C4 oxygenated VOC. It works by trapping the VOC out of the air onto a carbon adsorbent trap at -20�C with subsequent desorption at 350�C into a helium carrier flow. This instrument has a time resolution of 1 hour.

cv-dc-gc-fid

IO, BrO, NO3 and various other species

Long-path Differential Optical Absorption Spectrometer (LP-DOAS) measures scattered sun light to determine the amount of various trace gases along the 6km light path through the atmosphere. The basic quantity observed by the instrument is the integrated concentration of the trace gas along the light path.

IO, BrO and various other species

Multi-Axis Differential Optical Absorption Spectrometer (MAX-DOAS) works in a similar way to the LP-DOAS but observes scattered sunlight along different lines of sight, in particular at different elevation angles.
