Ambient air quality is primarily affected by respirable particulate matter (PM), SO2 and NO2 concentrations in the atmosphere. Monthly remote sensing data of SCIAMACHY tropospheric SO2 vertical column densities was measured from January 2004 to December 2010. OMI tropospheric SO2 vertical column densities was measured from October 2004 to December 2010. And daily ambient air pollution index (API)...
The climate change has significantly affected the carbon cycling in Yangtze River Basin. To better understand the alternation pattern for the relationship between carbon cycling and climate change, the net primary production (NPP) were simulated in the study area from 1956 to 2006 by using the Integrated Biosphere Simulator (IBIS). The results showed that the average annual NPP per square meter was...
Taking the South China Sea as the study area, the present paper aims to obtain the spatial and temporal distributions of chlorophyll-a, based on the chlorophyll-a data remote sensed by SeaWiFS from September 1997 to December 2010. Calculate the monthly average of chlorophyll-a concentration through space superposition and analysis the distribution characteristics. In consideration of space regional...
In this article, precipitation and subtropical high ridge axis of 500hPa are adapted for the new definition of North Huaihe-River Rainy Season (NHRS). The annual precipitation in NHRS and Meiyu (YHMY) from 1961 to 2009 is calculated by the summer daily rainfall in East China. The beginning day and ending day, as well as duration time in 49 years are also analyzed in this article for the two Rainy...
In the past three decades, Harmful Algal Bloom events have become more intense, frequent and widespread in the East China Sea driven by climate change and human impact. It appeared to be linked to heavy pollution loading and significantly reduced freshwater input due to drought or land-use change activities. Algal Bloom occurring can make Chlorophyll-a concentration abnormity, which as an very important...
As one of the indicators of the essential ecological characteristics of the sea area, the temporal and spatial variations of ocean chlorophyll-a is an important index to measure the distribution of phytoplankton, marine primary productivity and eutrophication status. Accurately detecting the temporal-spatial distributions of ocean chlorophyll-a with the remote sensing technology has significant importance...
Based on the remote sensing data of GOME and SCIMACHY, the paper analyzes the variation trend, temporal and spatial characteristics of NO2 column density from Apr. 1996 to Nov. 2009 in Yangtze Delta region. Besides that, seasonal analyses are also taken. In this session, a whole year is divided into dry season and rainy season. In spatial analyses, the paper emphasizes on the difference between NO...
The aerosol optical depth was affected by the chemical composition, the particle size and the shape of aerosol as well as the water vapor in the atmosphere; it is an important indicator for air pollution. The special and temporal characteristics of aerosol optical depth (AOD) was measured by CE318 sun-photometer, Angstrom wavelength exponent (α) and the aerosol turbidity coefficient (β) were calculated...
Urban agglomeration of Yangtze River Delta is the most developed one of three urban agglomerations in China, which consists of Shanghai, some cities located in the south of Jiangsu province and the north of Zhejiang province. Shanghai is an international economic, financial, trade and shipping center, which leads the progress of urban agglomeration of Yangtze River Delta. It is a lively region which...
