The general features, capabilities, and problems of in situ techniques are reviewed. To illustrate these capabilities more closely, examples of recent measurements are presented, including (1) resonance fluorescence for the measurement of O, OH, Cl, and ClO, (2) grab and cryogenic collection of whole air samples for the measurement of N 2 O, CFCl 3 , and CF 2 Cl 2 , (3) impregnated filters for HCl, and (4) matrix isolation for HO 2 and NO 2 .
