我们首次利用地面微波光谱对平流层变暖期间的水蒸气测量结果进行了分析。这些测量是1998年1月31日至2月10日在ALOMAR天文台（北纬69°，东经16°）进行的。资料显示，在整个变暖过程中，混合比在≈45 ~ 70 km之间增加。该分析使用了激光雷达从同一位置测量获得的温度数据。与使用标准温度数据获得的结果进行比较，揭示了在此类事件期间从遥感数据中检索水汽的“良好”温度测量的重要性，以便将温度效应与大气动力学分离开来。
We present the first analysis of water vapor measurements made during a stratospheric warming using ground‐based microwave spectroscopy. The measurements were made from the ALOMAR observatory (69°N, 16°E) between January 31 and February 10, 1998. The data show an increased mixing ratio between ≈ 45 and 70 km throughout the warming. The analysis uses temperature data obtained by lidar measurements from the same location. A comparison with results obtained using standard temperature data reveals the importance of ‘good’ temperature measurements for water vapor retrieval from remote sensing data during such events in order to separate temperature effects from atmospheric dynamics.
