Techniques are described for the measurement of atmospheric ozone, using the chemiluminescent reaction between ozone and rhodamine B. Details are given for a balloon sonde, for an aircraft‐installed ozone meter, and for a surface ozone recorder.

A device is described which uses the luminescence of a dry substance in the presence of ozone for the automatic quantitative determination of minute concentrations of atmospheric ozone. The sensitivity of the device is extremely high and the response is instantaneous. Since there are no liquid chemicals, the method can be used at extreme heights in the atmosphere, and it is equally applicable to the continuous monitoring of ozone near the earth's surface.

The downward flux of atmospheric ozone near the earth's surface is evaluated from recordings in Nebraska of the vertical profile of ozone and from simultaneous data on the wind profile and on the shearing stress at the surface. Furthermore, recordings of the ozone concentration in New Mexico at two levels which are 4,000 feet apart in altitude are used, together with the previously determined flux value, for an estimate of the coefficient of exchange in the atmosphere between the two stations. The observed differences in the ozone concentration at the two stations are also examined in relation to wind and temperature.

A chemical method for the automatic and quantitative recording of atmospheric ozone near the ground, from aircraft, or by means of sounding balloons, is described. A network of surface ozone recording stations is now being established in New Mexico and one airborne unit has been flown in an airplane. Preliminary recordings are communicated.
