New application software for Differential Optical Absorption Spectroscopy (DOAS) — •André Merten — Institut für Umweltphysik, Heidelberg

The opportunity offered by the Differential Optical Absorption Spectroscopy (DOAS) to do an automatic measurement and analysis of atmospheric trace gases has not been used because of the leak of adequate software. The requirements of modern measurement software were studied and a new, easier to handle DOAS-software based on Labview was developed, which can be used to monitor trace gases. It offers a complete control by Graphical User Interface, an automatic documentation mode and remote controlling via LAN or Internet. Passive as well as active DOAS devices (long path telescope, White Cell) can be controlled. As an example, an automatic trace gas monitoring system based on a long path telescope with modern LED light source, which can supervise air quality e.g. in urban as well in hazardous industrial areas is presented.
