Our space-based spectrometers allow the monitoring of the chemical content and gases in the atmosphere. This is of vital importance to understand issues such as global warming, ozone depletion and impacts of pollution on air quality. Our technology is also used for weather prediction and climatology. Our technology allows the global measurement of greenhouse gases to validate the effect of treaties such as the Kyoto protocol. Weather predictions increase our level of safety and our comfort. Accurately predicting the course of a hurricane can help save lives. Our technology allows to better understand the chemistry and dynamics of the atmosphere and provides the tools needed for scientists to build models to understand the mechanisms, as examples, of ozone depletion or the impacts of greenhouse gases on global warming.
