We describe the development of a differential absorption lidar (DIAL) at Goddard Space Flight Center designed to make range resolved measurements of CO2 within the planetary boundary layer (<3000 meters). The goal is to develop a compact, rugged, instrument capable of autonomous operation using commercial-off-the-shelf components and technology. The spatial and temporal variations in CO2 will permit fluxes to be derived and terrestrial sources and sinks to be identified. Simulations indicate that the system will make measurements at a precision of ppmv at 4000 meters with 10 minutes receiver integration time and a vertical resolution of 150 meters. Data will be presented. The concurrent development of a small, compact optical parametric amplifier as a light source for this lidar will be discussed. Future directions for this research will be presented.
