| Research Abstract |
We started the monitoring of seasonal variation and dynamic solution of atmospheric pollution around Toyama bay area. Aerosol optical properties are studied using data from sun and sky radiometer measurements in the Toyama, Mt.Jodo/Tateyama, and Suzu. The radiometer is an automatic instrument that takes observations under the condition of air pollution from local and/or long distance. The aerosol optical thickness at 0.5 μm has a clear seasonal cycle, with a vernal maximum and an autumnal minimum, but on the Toyama bay, the seasonal cycle is sometimes early summer maximum.
