Evaluation of long-term tropospheric NO2 columns and the effect of different ecosystem in Yangtze River Delta |
Abstract | ||
---|---|---|
The spatial and temporal characters of NO2 over Yangtze River Delta (YZD) are analyzed using monthly averaged tropospheric & column densities from GOME (1996-2002) and SCIAMACHY (2003-2010) measurements. In addition, with the land cover map of YZD, the characters of NO2 concentration over different ecosystem have been analyzed. The results indicated that the tropospheric NO2 column densities in YZD increased distinctly from 1996 to 2010 and it showed distinct regional and seasonal variation. It has the highest concentration in winter while lowest in summer. Under the influence of the urbanization process, the highest NO2 column densities appeared at cities and metropolis while the lowest column densities appeared in forest. The sharp increasing of tropospheric NO2 column appeared in water bodies, followed urban land and woodland. Furthermore, we compared with the NO2 column and the mass concentration of N dry deposition from the control experiments, they performed significant correlation and the high R value (R2=0.86, P<;0.001). |
