■ The principle of distinguishing aslocards with rider
In the observation of yellow sand, it is important to determine whether the scattered body is yellow sand or an air pollution aerosol. Riders with polarized measurement functions can identify yellow sand by using the change in polarized light (polarized resolution) due to scattering. This polarized elimination is an indicator of the degree of astrozen. The aerosol of the liquid phase, such as the aerosol sulfate due to air pollution, is spherical, but the yellow sand of mineral particles is astropular, so it has a high level of polarization and can be sensitive to yellow sand.

* In recent years, from February to May in early spring, the flying observations of yellow sand have been reported. Many of these yellow sands occur in the Chinese Gobi Desert, Takramakan Desert, etc. and are transported and flyed by strong seasonal winds. In Japan, there is a major impact on various fields such as damage to transportation, such as the departure and arrival of passenger aircraft, and in China. In addition, there is concern about the impact on the living environment and health, which is a chemical reaction with the emissions from the human source, etc., and research has been promoted led by the National Institute of National Environmental Institute and the China -Japan Friendship Environmental Conservation Center. 。 This yellow sand is rolled up to high altitude and is transported by airflow above the air over the ground. For this reason, it is important to measure altitude distribution observations up to several kilometers above ground. In the past, visual observations were limited to the ground, and it was difficult to determine whether it was frog or yellow sand. For this reason, a new rider device has been developed, enabling real -time measurement of altitude distribution.
