JMA’s routine aerosol observations and Activities in the RRC Ⅱ kohei HONDA Regional Radiation Center (RRC) II (Asia) Global Environment and Marine Department Japan Meteorological Agency (JMA)
JMA Aerosol / Turbidity Group _ 3 Sunphotometers _ 1 LIDAR _ 14 Pyrheliometers We are controlling routine aerosol observations with... Satellite data And we are also processing... There is an “Aerosol / Turbidity Group” in the Atmospheric Environment Division of the JMA Headquarters.
Sunphotometer Site : Ryori (since 1988) Minamitorishima (since 1995) Yonagunijima (since 1998) Instruments : EKO MS-110 Renewal Plan: PFR( ) Center wavelength : 368, 500, 675, 778, 862nm Observation time : 3 times / day EKO MS-110 Sunphotometer (Minamitorishima) Monthly Mean AOD (Minamitorishima)
Calibration The Langley observation has been conducted at the Japan Central Alps (2,612m a.s.l) since All sunphotometers are calibrated once a year by the Langley method. J0J0 JMA use WORCC to calibration PFR near future.
