| description | Knowledge of present carbon sources and sinks including their spatial distribution and their variation in time is one of the essential information for predicting future CO2 atmospheric concentration levels. The differential absorption lidar (DIAL) is expected to measure atmospheric CO2 profiles in the atmospheric boundary layer and lower troposphere from a ground platform.
We have succeeded to develop a compact 1.6 μm DIAL system for measuring CO2 concentration
profiles in the lower atmosphere. This 1.6 μm DIAL system consists of the optical parametric
generator (OPG) transmitter that excited by the LD pumped Nd:YAG laser with high repetition
rate and the receiving optics that included the near-infrared photomultiplier tube operating at the
analog mode and a 25 cm telescope. CO2 concentration profiles were obtained up to 2.5 km
altitude. |
