It works in synergy with Sweden's advanced radiometer and measures atmospheric composition.\r\n\r\nSince 2001, OSIRIS has obtained valuable information on the upper atmosphere. It focuses its attention on altitudes from 7 to 90 km—between the highest mountains and the edge of space—and measures concentrations of ozone, aerosols and nitrogen dioxide.\r\n\r\nData provided by OSIRIS helps scientists better understand the impact of human activities and natural phenomena on the environment and climate.",
