臭氧对太阳紫外线变化的响应是在10到0.2毫巴高度之间的中间大气中确定的。只有在消除了与温度变化有关的臭氧的较大变化之后，才能最终隔离与短期太阳变化有关的较小变化。利用这一方法，消除趋势臭氧(Nimbus 7 LIMS)与太阳短期205 nm变化(Nimbus 7 SBUV)之间的相关系数远高于以往的研究结果(0.9)。中层大气臭氧对太阳紫外线短期变化的理论响应时间和响应幅度与观测值基本一致，但在0.2毫巴附近除外。对太阳周期的相应长期响应也进行了估计。
The response of ozone to solar UV variation is determined in the middle atmosphere between the heights of 10 and 0.2 mb. The definitive isolation of the smaller variations associated with short-term solar variability is accomplished only after removal of the larger changes of ozone related to temperature variations. Using this approach the correlation coefficients between detrended ozone (Nimbus 7 LIMS) and short-term 205 nm solar variation (Nimbus 7 SBUV) are found to be much higher (0.9) than achieved in previous studies. The theoretical response time and amplitude of response of ozone in the middle atmosphere to observed short-term solar UV variations is found to be in good agreement with observations, except near 0.2 mb. The corresponding long-term response over the solar cycle is also estimated.
