Description
Summary:The development, applications and intercomparisons of instrumentation and measurement techniques for ground-based and airborne field studies of gas-phase tropospheric chemistry are reviewed. Filter radiometry, chemical actinometry and scanning spectroradiometry for j-NO 2 and j-(O 1 D) are described. Detection of OH using L-POAS/DOAS, MOAS, LIF/FAGE and CIMS is discussed. Observations of NO 3 using DOAS, MIESR and CRDS, and of HO 2 and RO 2 with CA, CIMS/IMR-MS, MIESR, and LIF/FAGE are also reviewed. GC-FID, GC-ECD and GC-MS analyses of NMHCs and alkyl, peroxyacyl and bi-functional organic nitrates are described, together with applications of CIMS/PTR-MS, DOAS and LIF. CO measurements utilising GFC, GC-HgO/UV, VUV-RF and TDLAS are presented. Measurements of O 3 using UV photometry, chemiluminescence, electrochemistry, LIDAR/DIAL and DOAS are discussed. Chemiluminescence and LIF detection methods for NO with photochemical and thermal convertors for NO 2 and NO y are also discussed, as are TDLAS, MIESR, DOAS, CRDS and other approaches for NO 2 . HONO measurements using DOAS, CIMS, CRDS, TDLAS, denuder systems, chemiluminescence and on-line analyses of NO 2 − are described. For HONO 2 , filter packs, denuder systems, chemiluminescence methods, mist chambers, TDLAS, CIMS and LIF are presented. Direct and indirect fluorimetric, chromatographic and spectroscopic detection techniques are discussed for CH 2 O and higher carbonyls. Observations of H 2 O 2 and ROOH utilising colorimetry, chemiluminescence, fluorescence, HPLC and TDLAS are also described.
