Sunphotometer Site : Ryori (since 1988) Minamitorishima (since 1995) Yonagunijima (since 1998) Instruments : EKO MS-110 Renewal Plan: PFR(2005-2006) Center wavelength : 368, 500, 675, 778, 862nm Observation time : 3 times / day EKO MS-110 Sunphotometer (Minamitorishima) 1998 1999 2000 2001 2002 Monthly Mean AOD (Minamitorishima) 1.0 0.5 0.0

5. Calibration The Langley observation has been conducted at the Japan Central Alps (2,612m a.s.l) since 1997. All sunphotometers are calibrated once a year by the Langley method. J0J0 JMA use WORCC to calibration PFR near future.
