1998年9月至10月和1999年8月至9月在印度尼西亚海洋大陆进行了臭氧探测运动。每次活动使用三个站点，1998年活动使用瓦图科塞克（7.5°S,112.6°E）， Kototabang（0.20°S,100.3°E）和Pontianak(0.03°N,109.3°E)， 1999年活动使用瓦图科塞克，Kototabang和达尔文（12.25°S,130.55°E）。这两个时期的特征基本都为La Niña期，对流层臭氧浓度呈正常值。在1998年的观测活动中，获得了两个赤道站对流层顶下方1 - 1.5 km厚度的臭氧层状结构的时间变化和水平分布。包括反向区域填充技术在内的气象数据分析表明，对该层最合理的解释是来自中纬度北部平流层下层的准水平薄侵入，与破裂的罗斯比波和大规模流动模式有关。

Ozonesonde observation campaigns were conducted over the Indonesian maritime continent in September–October 1998 and in August–September 1999. Three stations were used for each campaign, Watukosek (7.5°S,112.6°E), Kototabang (0.20°S,100.3°E), and Pontianak (0.03°N,109.3°E) for the 1998 campaign, and Watukosek, Kototabang, and Darwin (12.25°S,130.55°E) for the 1999 campaign. Both periods were basically characterized as the La Niña period, and the tropospheric ozone concentrations showed normal values. Temporal variation and horizontal distribution of an ozone layered structure with a 1–1.5-km thickness were obtained just below the tropopause at the two equatorial stations during the 1998 campaign. Meteorological data analyses including the reverse domain filling technique suggested that the most plausible explanation for the layer is the quasi-horizontal, thin intrusion from the northern midlatitude lower stratosphere associated with a breaking Rossby wave and large-scale flow pattern.
