We investigate not only the concentration of aerosol but also particle size, mixed state, shape etc by the original online-measurement techniques.

 

These microphysical properties are critical factors determining the wet removal efficiency and radiative properties of aerosol.

We often participate the domestic or international aircraft observation campaign.

 

Aircraft measurement is crucial for investigating the large-scale  transport/removal process of aerosols and gases.

Aerosol particles removed with rainwater carries unique information on the wet removal process. 

 

We use water-insoluble black carbon particles as a physical tracer of the cloud-processing of aerosols.

One of out major targets in field measurement is East Asian continental outflow, considering the large contribution of East Asia to global anthropogenic aerosol emission.

​

We use these data for constraining emission assumed in regional and global aerosol modelings。
