Description

technical field

[0001] The invention relates to a near-surface atmospheric composition measuring device, in particular to a movable atmospheric composition sensing and measuring device. Background technique

[0002] Because the composition of the atmosphere plays an important role in the radiation process of the earth-atmosphere system, the cumulative result of its concentration changes will cause the earth's climate to change. At the same time, changes in the concentration of some atmospheric components will cause changes in the concentration of other atmospheric components, thereby indirectly affecting the climate. Therefore, the research on the concentration change of atmospheric components becomes more and more important. Surface emission is an important source of atmospheric components, and it has become a very important content to study its composition, concentration and distribution, as well as near-surface atmospheric vertical flux. There are two main categories of...
