Outline of Final Research Achievements

This study try to put portable and affordable ozone sensor to practical use.
In a study period of 3 years, toward the practical realization of the ozone sensor, we conducted studies for 1) identification of environmental conditions affecting the sensor response, and establishment of a calibration method, 2) development of monitoring data transmission system, and 3) application of ozone sensor to environmental measurement in a distant area and a forest area.
As a result, it was shown that automatic and unmanned environmental monitoring with the sensors is possible when the sensor is calibrated for the seasonal variation of ambient temperature, and this sensor can greatly contribute to forest impact evaluation of ozone.
