摘要: The general features, capabilities, and problems of in situ techniques are reviewed. To illustrate these capabilities more closely, examples recent measurements presented, including (1) resonance fluorescence for the measurement O, OH, Cl, ClO, (2) grab cryogenic collection whole air samples N2O, CFCl3, CF2Cl2, (3) impregnated filters HCl, (4) matrix isolation HO2 NO2.
