“…The measurements of total reactive nitrogen by Webster et al [1990], and by ATMOS [ Russell et al ., 1988] are also in reasonable agreement with each other. Kondo et al . [1989, 1990b] have measured the altitude profiles of NO and NO y at 45°N that are matched by model predictions, and Kondo et al [1990c] use the diurnal variation of NO to calculate NO y and N 2 O 5 mixing ratios that agree with other measurements.…”

“…The catalytic reaction cycle of atomic oxygen and ozone with nitric oxide (NO) and nitrogen dioxide (NO2) is estimated to be the major loss process for ozone throughout the stratosphere below about 40 km [e.g., McElro•t and Salawitch, 1989]. In addition, these oxides of nitrogen (NO=) interact with reactive chlorine species in the following way: NO reacts with C10 through the reaction Observations of the diurnal variation of NO in the upper stratosphere are very limited; however, at lower altitudes, more observations have been made, mainly with in situ chemiluminescence NO detectors [e.g., Ridley et al, 1977;Kondo et al, 1985Kondo et al, , 1988Kondo et al, , 1989a, b] (see Kondo et al, [1988] for a more complete set of references). Ridley and Schiff [1981] measured the temporal variation of NO at 40 km near sunset.…”

Two recent measurements of the temporal variation of nitric oxide at constant altitude near 40 km are reported. The observations were made at float altitude with a balloon‐borne chemiluminescence detector together with in situ ozone measurements. The first measurement was made at 44°N on September 17, 1987, at an altitude of 40 km from before sunrise until 1000 LT. The second observation was made at the same latitude on June 18, 1988 at 39 km from 0800 to 1230 LT. The precision of the NO measurements is about 10% at these altitudes, obtained through a more accurate determination of the sample flow rate at pressures down to 2 mbar with a reduced ozone/oxygen flow rate. At an altitude of 40 km, nitric oxide was observed to start increasing very rapidly at sunrise when the solar zenith angle reached about 95°. After the rapid initial buildup, the rate of NO increase stabilized for 3 hours at about 1.2 ppbv/hour. Near 1100 LT at 39 km in summer the NO mixing ratio was observed to become nearly constant. These features of the diurnal variation of NO are in accord with the temporal variation expected from a time‐dependent zero‐dimensional photochemical model. Mixing ratios of NOy and N2O5 have been determined from the measured temporal variation of NO at 39.5±0.5 km, using the photochemical model of Pirre et al. (1989). These derived values of the NOy and N2O5 mixing ratios, 15.5±5.0 ppbv and 1.4±0.6 ppbv, respectively, are in good agreement with other recent measurements by balloon‐borne and space‐borne infrared experiments.

During the European Arctic Stratospheric Ozone Experiment (EASOE) the Arctic stratosphere was investigated with a set of instruments flown on a CNES high altitude balloon from ESRANGE, northern Sweden (67°52′N, 21°4′E) on January 22, 1992. The vertical profiles to an altitude of 30 km are presented for ozone, nitric oxide, aerosols, and the temperature. The ozone mixing ratio was less than 0.1 ppmv below 13km, and increased significantly only above the 18.5 km level. The aerosol concentration profile shows a large peak between 13 km and 21km, centered at 18.5 km, reaching as high as about 10 particles/cm³. Above 24 km the aerosols were absent. Below 22 km, the NO mixing ratio was lower than 50 pptv; however it increased rapidly from 23 km with a sharp peak at 27 km. The rapid increase in NO occurs just at the altitude where the aerosol concentration falls below the detection limit: on this day, NO was present only in the absence of aerosols.
