The Japanese Reanalysis for Aerosol (JRAero) is a global aerosol reanalysis product construnted by the Meteorological Research Institute (MRI) of the Japan Meteorological Agency (JMA) and the Research Institute for Applied Mechanics (RIAM) of Kyushu University (KU).
JRAero is extended to the end of 2019!

Available Data

  • Period: 1 Jan. 2011 - 31 Dec. 2019 (Extended for two years)
  • Temporal resolution: 6 hour
  • Horizontal resolution: approximately 1.1° × 1.1° (TL159: 320 × 160 grid points)
  • 2-D variables
    • Aerosol Optical Depth (total, dust, sea salt, BC, OC, sulfate)
    • Surface PM2.5 and PM10 concentration [μg/m3]
    • Wet and dry deposition (dust, sea salt, BC, OC, sulfate) [kg/m2/s]
    • (Downward Long- and Short-wave Radiations [w/m2]; optional)
    • (Dust and sea salt emissions [kg/m2/s]; optional)
  • 3-D variables
    • Extinction coefficient (total, dust, sea salt, BC, OC, sulfate) [1/km]

JRAero Atlas

The JRAero Atlas provides daily maps of AOD, PM2.5 concentration, and dust deposition produced by JRAero aerosol reanalysis. It would be widely useful in quick look, research and education.
