Calibration of Members' standards

RIC Tsukuba calibrates Members' standard instruments via the method outlined below.

The Member sends the standard meteorological instrument for calibration to RIC Tsukuba, which calibrates it against its own standard. This is the regional standard for RA II.
(Applicable to barometers, thermometers, hygrometers and anemometers)

Since its establishment in 1998, RIC Tsukuba has helped to maintain and improve the quality of meteorological observation data via the calibration of WMO Members' standards both in RA II and elsewhere as listed below.
