Paper Abstract

Up-link Laser Differential Absorption Sensing: ULDAS, shown in Fig.1, is a new method to measure green house gas concentration with earth observation satellites. Although the measurement area is restricted in only small visible area of an optical ground station, ULDAS has outstanding features as followed:

- Faster: Easy to development, small size and small resource requirements to satellite system

- Better: High accuracy (CO2 observation error of weighted column is <0.3% which corresponds to 1ppm error of atmospheric concentration)

- Cheaper: Simple system, small number of parts and no special parts

The flight segment of the ULDAS is able to be loaded on a marginal resource of green house effect observation satellites, such as Japanese GOSAT-series. In this paper, the feasibility study of the mission concept and field experiments are reported.
