Air Quality Warning, Japan

If you have allergies, the SPRINTARS page may help you to prepare for your daily tasks.

Red alert means severe warning
Orange means pretty bad
Green means yaya, a little bad
Blue means OK...

Sunday was severe in many places, including Tohoku and Kyushu. But Monday should be OK.

SPRINTARS Forecast (J) The aerosol forecast is based on the simulation with a global aerosol climate model, SPRINTARS (E). Their movies are rather interesting too, here.

Here is the link to their daily forecasts:

SPRINTARS also do video forecasts of pollutants.

Try this link. Wow, China really gets it bad.

SPRINTARS is based on an atmosphere-ocean general circulation model, MIROC, developed by Atmosphere and Ocean Research Institute (Division of Climate System Research), University of Tokyo, National Institute fot Environmental Studies, and Japan Agency for Marine-Earth Science and Technology (Research Institute for Global Change), and treats main tropospheric aerosols both from natural and anthropogenic sources (black carbon, organic matter, sulfate, soil dust, and sea salt). They are also categorized into PM10 and PM2.5. SPRINTARS calculates transport processes of aerosols (emission, advection, diffusion, wet deposition, dry deposition, and gravitational settling). The aerosol direct effect, which is scattering and absorption of solar and thermal radiation by aerosols, and the indirect effect, which is act of aerosols as cloud condensation nuclei and ice nuclei, are included in the calculation.
