Analysis of the Relationship between Changes in Meteorological Conditions and the Variation in Summer Ozone Levels over the Central Kanto Area

Table 1

Variables used in the regression analysis.

Variables	Definition
Ozone (O3)	(i) Seasonally averaged daily maximum value of environmental monitoring sites in the Tokyo area (see Figure 8) for the summers from 1985–2005. O3 concentrations are expressed in ppb.
	(ii) Averaged daily maximum value of environmental monitoring sites in the Tokyo area in August 2005.
Temperature (T)	(i) Seasonally averaged daily maximum values at the Nerima meteorological site for the summers from 1985–2005. Temperatures are expressed in °C.
	(ii) Averaged daily maximum values of environmental monitoring sites in the Tokyo area in August 2005.
Wind speed (U)	(i) Seasonally averaged values at the Nerima meteorological site for the summers from 1985–2005. Wind speeds are expressed in m⋅s^−1.
	(ii) Daily averaged values of environmental monitoring sites in the Tokyo area in August 2005.
