Differential Absorption LIDAR for Greenhouse Gas Detection

, 2012
Our goal is to develop and characterize measurement technology for ground-based quantification of greenhouse-gas emissions from natural and anthropogenic sources and sinks. Toward this end, we are developing a differential absorption LIDAR (DIAL) system capable of remote measurements of atmospheric levels of the major greenhouse gases with 10-100 meter

Pulsed Airborne Lidar Measurements of C02 Column Absorption [PDF]

, 2011
We report on airborne lidar measurements of atmospheric CO2 column density for an approach being developed as a candidate for NASA's ASCENDS mission. It uses a pulsed dual-wavelength lidar measurement based on the integrated path differential absorption (
