生物质燃烧对中国东北地区CO浓度的影响研究

利用Aqua卫星上AIRS传感器的近地表和500hPa气压层高度的CO数据,研究了中国东北地区2012年CO时空分布特征及其变化趋势,并结合MODIS火点资料以及NCEP/NCAR的风场资料,分析了当地的生物质燃烧以及周边国家和地区CO远距离输送对研究区CO浓度的影响。研究结果表明:近地表CO浓度高值出现在冬季和春季,低值出现在夏季和秋季,2011~2013年连续3a的CO浓度与火点数的相关关系均在0.52左右,显著相关。此外,CO的分布还与当地的供暖时间、人口密度和工业分布有关:CO的高值时间与中国东北地区冬季供暖时间基本一致,人口和工业集中地区的CO浓度偏高,人口稀少的内蒙古草原CO浓度值偏低;根据NECP/NCAR的风场资料,中国东北地区500hPa气压层高度全年受来自西伯利亚和蒙古国的西北风影响,东北地区,尤其是内蒙古自治区,西伯利亚和蒙古国常年有大量火点,在500hPa气压层高度的CO浓度受西伯利亚和蒙古国的影响。生物质燃烧能够反映农作物收获时间,CO浓度的时空变化规律也能在一定程度上反映我国农作物的时空分布特征,具有重要的研究意义。     

多源雪深数据在中国的空间特征评估

积雪的年际和年内变化强烈地影响着区域及全球的水量平衡，同时，积雪反照率反馈也显著地影响着气候变化。目前长时间序列的格网雪深数据主要来自被动微波遥感及再分析资料，但不同数据之间存在着明显差异。基于多源雪深数据的评估，特别是空间特性的评估还很缺乏。因此，本研究选取了AMSR-E、WESTDC、GlobSnow、RA-Interim及MERRA2这5种雪深数据，以站点观测数据为参考真值，对它们进行了中国地区的空间误差对比及基于误差排序的相对表现分析。评估结果初步显示：①WESTDC在我国西北及东北积雪区表现较好，适合用于我国北方的雪深研究；②MERRA2在西北和东北积雪区也有较好的表现，但由于其分辨率较粗，缺乏细节的空间信息，因此认为比较适用于大区域的统计分析；③AMSR-E在我国中部和东南地区表现最好，因此认为适合我国中部及东南部的雪深研究。

East Hainan upwelling fronts detected by remote sensing and modelled in summer

Using the Belkin and O’Reilly algorithm and high-resolution (1 km) satellite sea surface temperature (SST) and chlorophyll-a (chl-a) data from 2002 to 2011, fronts were detected off the east/northeast coast of Hainan Island, South China Sea. These fronts were mainly produced by upwelling off eastern Hainan Island, through which cold, high-salinity, high-density, and nutrient-rich bottom water was brought to the surface and subsurface and then transported to the northeast of Hainan Island by the along-shore currents. The fronts are anisotropic, with a dominant orientation SSW–NNE. A three-dimensional ocean model forced by the Quick Scatterometer (QuikSCAT) winds was employed to study the three-dimensional structure of these fronts as well as the relationship between the fronts and upwelling or summer monsoon. The results show that the front intensity (cross-frontal gradient) is strongly correlated with the along-shore local winds, and has a strong seasonal and a weak inter-annual variation with a maximum of about 0.5°C km^–1 at the subsurface (about 15 m) rather than the surface.     

Observation of an agricultural biomass burning in central and east China using merged aerosol optical depth data from multiple satellite missions

Agricultural biomass burning (ABB) in central and east China occurs every year from May to October and peaks in June. During the period from 26 May to 16 June 2007, one strong ABB procedure happened mainly in Anhui, Henan, Jiangsu and Shandong provinces. This article focuses on analysis of this ABB procedure using a comprehensive set of aerosol optical depth (AOD) data merged by using the optimal interpolation method from the Moderate Resolution Imaging Spectroradiometer, the Multi-angle Imaging Spectroradiometer (MIRS) as well as Sea-viewing Wide Field-of-view Sensor (SeaWiFS)-derived AOD products. In addition, the following additional data are used: fire data from the National Satellite Meteorological Centre of China Meteorological Administration, the mass trajectory analyses from hybrid single-particle Lagrangian integrated trajectory (HYSPLIT) model and ground-based AOD and Ångström data derived from the Aerosol Robotic Network and China Aerosol Remote Sensing Network. The results show that merged satellite AOD values can expand the spatial coverage of agricultural biomass aerosol distributions with good accuracy (R = 0.93, root mean square error = 0.37). Based on the merged AOD images, the highest AOD values were found concentrated in central China as well as in eastern China before 6 June and further extended to northeast China after 12 June. AODs from ground measurement show that eastern China always keeps high AOD values (>1.0), with a maximum exceeding 3.0 and extending as high as nearly 5.0 during this ABB event. With the help of the HYSPLIT model, we analysed the ABB sources and examined how transport paths affect the concentrations of air pollutants in some sites. The results show that Henan, Jiangsu and Anhui provinces are the three main sources in this ABB.

Spatial Pattern of Regional Urbanization Efficiency: An Empirical Study of Shanghai

China is the fastest urbanizing area in the world. The complex urban systems not only create more socioeconomic output (such as GDP), but also bring more infrastructural costs and environmental losses. Thus, urban research has concentrated on urbanization efficiency toward efficient and spatially coordinated instead of urban size. In this paper, we use data envelopment analysis (DEA) to estimate how well districts in Shanghai utilize their resources. Based on data for five inputs and three outputs, we applied an input-oriented BBC Model and an output-oriented CCR Model for Decision Making Units (DMUs) assessment and urbanization efficiency analysis. In addition, the spatial pattern of relative urbanization efficiency is examined by spatial autocorrelation model. The research result indicates that it is in downward trend mainly affected by technical constraints, 11 out of 17 districts in Shanghai are efficient, and the urbanization efficiency gap between Pudong New district and Huangpu district is significant. The districts’urbanization efficiency in south areas are higher than that in middle and northeast area.     

Evaluation of PARASOL aerosol retrieval over North East Asia

The third POLDER (POLarization and Directionality of the Earth Reflectance) instrument, PARASOL (Polarization & Anisotropy of Reflectances for Atmospheric Sciences coupled with Observations from a Lidar) was launched in December 2004 and started its operational life at the early beginning of March 2005. This study is devoted to the regional validation of PARASOL aerosol retrieval scheme over land surfaces against independent automatic sun-photometers located in the northeast part of China at the Beijing and Xianghe sites both included in AERONET (Aerosol Robotic Network). PARASOL Level 2 Aerosol Optical Thickness (AOT) is shown, thanks to the high quality sun-photometer dataset, to be quite consistent with the AERONET AOT of the fine fractional part of the size distribution (radius ≤ 0.3 μm). In other words, PARASOL retrieval over land is mainly sensitive to the anthropogenic aerosols which are known for influencing the climate, environment as well as human health. Moreover, analysis of polarization in the 490 nm band (Level 1 data) shows the possibility of dust type aerosol identification thus yielding to a potential algorithm improvement in the future.

Seasonal and spatial distribution of chlorophyll-a concentrations and water conditions in the Gulf of Tonkin, South China Sea

The Gulf of Tonkin is a semi-closed gulf northwest of the South China Sea, experiencing reversal seasonal monsoon. Previous studies of water conditions have been conducted in the western waters of the gulf, but very few studies of the Chlorophyll-a (Chl-a) distribution have been carried out for the entire gulf. The present study investigates seasonal and spatial distributions of Chl-a and water conditions in the Gulf of Tonkin by analyzing Sea-viewing Wide Field-of-View Scanner (SeaWiFS) derived Chlorophyll-a (Chl-a), in situ measurements, sea surface temperatures (SST), and other oceanographic data obtained in 1999 and 2000. The results show seasonality of Chl-a and SST variations in the Gulf of Tonkin, and reveal phytoplankton blooming events in the center part of the gulf during the northeast monsoon season. In summer, Chl-a concentrations were relatively low (<0.3 mg m⁻³) and distributed uniformly throughout most of the area, with a belt of higher Chl-a concentrations along the coast, particularly the coast of Qiongzhou Peninsula; in winter, Chl-a concentration increased (0.5 mg m⁻³) in the entire gulf, and phytoplankton blooms offshore-ward from the northeast coast to the center of the gulf, while Chl-a concentrations reached high levels (0.8-1 mg m⁻³) in the center of the blooms. One peak of Chl-a concentrations was observed during the northeast monsoon season in the year. SST were high (27-29 °C) and distributed uniformly in summer, but lower with a large gradient from northeast (17 °C) to southwest (25 °C) in winter, while strong northeast winds (8-10 m/s) were parallel to the east coast of the gulf. Comparison of Chl-a values shows that SeaWiFS derived Chl-a concentrations match well with in situ measurements in most parts of the gulf in May 1999, but SeaWiFS derived Chl-a are higher than in situ data in river mouth waters. The seasonal variation of Chl-a concentrations and SST distribution were associated with the seasonally reversing monsoon; the winter phytoplankton blooms were related to vertical mixing and upwelling nutrients drawn by the northeast wind.
