Abstract

Average of air quality status in Surabaya in good condition status only less than 24% in a year (Anonymous, 2008). Dispersion of pollutants in the ambient is affected by meteorological factors and height of the inversion layer that limit the mixing height in the city of Surabaya. This study was conducted to analyze the relationship between meteorological factors and the height of the inversion layer, and also the ambient air quality in the city of Surabaya. Correlation of meteorological factors on the inversion layer height and ambient air quality in the city of Surabaya analyzed by Pearson correlation method. Correlations were conducted assumed under normal conditions so the meteorological data (wind speed and global radiation) and air quality (concentration of SO2, NO2 and O3) that is used is from the data scoping (00.00 am and 12.00 pm) with the 10% percentile value. The data obtained from the inversion layer height profile radiosonde temperature measurement results. Inversion layer in Surabaya is a subsidence inversion. The inversion layer is inversely correlated at 00:00 pm and is directly proportional correlation at 12.00 against the wind speed, while not correlated to the strength of the radiation. Correlation of inversion layer height with SO2 concentration of ambient air quality is inversely related, but not correlated with NO2 and O3. While the wind speed is negatively correlated with NO2. Radiation strength parameters were negatively correlated with SO2 and NO2, but the correlation is directly proportional to O3.
