Abstract

It has become clear that in order for lidar technologies to gain wider acceptance outside the research community, they must be smaller, less expensive, and more autonomous. ERIM International has conducted a design study to determine the minimum package size for a fieldable tropospheric ozone lidar. After considering several different wavelength pairs for the differential absorption lidar measurement, a design was selected based on Raman shifting the 4th harmonic of an Nd:YAG laser from 266 nm to 289 nm using deuterium and from 266 nm to 299 nm using hydrogen. Model results indicate that the three wavelengths used in concert will allow measurements of ozone out to a range of nearly 5 km with an accuracy of 5 ppb or better with a one hour integration time. The overall system design consists of a sensor head mounted inside a small shipping crate with the laser, Raman shift tubes, receiving telescope, and detectors and separate data collection/control module in a rugged case. It is anticipated that the system could be built in a combined package occupying less than 2 m³.
