Ozone concentrations at a high altitude station in the Central Massif (Spain)
چکیده انگلیسی
In order to contribute to current knowledge of ozone concentrations and transport across the Central Massif, a monitoring station was installed at 1780 m on the upper Spanish plateau about 55 km from the city of Madrid. Ozone concentrations and standard meteorological variables were measured in June and July 2002. A smoothed ozone hourly cycle was obtained with mean values of 120 and 110 μg m−3 during day-time and night-time, respectively. The highest ozone concentrations were recorded in the SE-S-SW wind sectors, proving the influence of transport from the Madrid urban plume to the upper plateau. This assumption was also supported by the satisfactory correlation between ozone peaks obtained at the monitoring site and those recorded in a representative station on the foothill located on the lower plateau during episodic situations. To assess the contribution of long-range transport, backward air mass trajectories were computed each day of measurements at 820 hPa. The lowest ozone mean was linked to Atlantic Ocean air masses, and the highest to air masses from Central Europe.
