The goal of this project is to measure changes in O3 and H2O in the stratosphere and mesosphere in the Arctic at Ny-Ålesund/Spitsbergen and the Tropics at Mérida/ Venezuela with special emphasis on the effects due to solar variability. These measurements will allow us to study the following scientific topics:- Measure the influence of the diurnal and seasonal variability of water vapour on the ozone chemistry in the tropics compared to the high Arctic.- Investigate the influence of UV variability compared to the influence of charged particles on ozone by comparisons of measurements at the two sites.- Estimate the vertical transport of mesospheric air downward into the upper and middle stratosphere.- Assess the long-term impact of variations in water vapour concentrations on the stratospheric ozone chemistry in the Arctic and the Tropics.

该项目的目标是测量北极Ny-Spitsbergen岛平流层和中间层O3和H2O的变化以及委内瑞拉Mérida岛热带平流层和中间层O3和H2O的变化，特别强调太阳变化的影响。这些测量将使我们能够研究以下科学主题：-测量热带地区与北极地区相比，水蒸气的昼夜和季节变化对臭氧化学的影响。通过比较两个地点的测量结果，调查紫外线变化的影响与带电粒子对臭氧的影响。估计中层空气向下进入平流层上部和中部的垂直输送。评估水蒸气浓度变化对北极和热带平流层臭氧化学的长期影响。
