Related Information

In addition to LIDAR data, SPM data and visibility data are also important DSS information. Monitoring data of PM10 in China and Korea can also be used as one source of information on DSS blown to Japan.

SPM Data


Since DSS consists of particulate matter, monitoring results of SPM also serve as a reference for the real-time conditions of DSS blown to the ground level. However, it should also be noted that SPM monitoring data do not represent the concentrations of DSS by themselves. From "Atmospheric Environmental Regional Observation System: AEROS"(Japanese text only), click the region that you want to view, and select浮遊粒子状物質(SPM) to view the data. Please refer to the English guidance document on how to see the AEROS for your support.
