The middle atmosphere is a region of the atmosphere extending from about 10 km altitude up to near the edge of space (about 85 km altitude). The stratosphere, which is the lowest part of the middle atmosphere, has become an important area of research because changes in the nature of the stratosphere are coupled to changes at the Earth's surface that effect our daily lives. We will study satellite measurements of the atmosphere to investigate the processes and trends that take place in the stratosphere. In particular, we will use measurements from the Canadian OSIRIS satellite instrument. These measurements, which essentially cover the globe every day, can be used to detect the amount and vertical structure of ozone, clouds, and aerosols, which in this context may be small liquid droplets or particles of dust, smoke or ice.

中层大气是大气层的一个区域，从大约10公里的高度一直延伸到接近空间的边缘（大约85公里的高度）。平流层是中层大气中最低的部分，它已经成为一个重要的研究领域，因为平流层性质的变化与地球表面的变化相关联，影响着我们的日常生活。我们将研究大气的卫星测量，以调查平流层中发生的过程和趋势。特别是，我们将使用加拿大OSIRIS卫星仪器的测量结果。这些测量基本上每天覆盖全球，可用于检测臭氧、云和气溶胶的数量和垂直结构，在这种情况下，这些气溶胶可能是小液滴或尘埃、烟雾或冰的颗粒。
