Particles produced by secondary processes may play an important role in climate variability.Condensation Particle Counters (CPC) with different cut-off diameters (TSI CPC model 3025 (and 3776): D > 3nm and 3010 (and 3772): D > 10 nm) and an Optical Particle Counter (OPC,Grimm model 1.108) were deployed at the King Sejong station (KSJ,62.22 o S,58.78 o W) to measure total particle number concentration and size distributions during austral summer seasons ((i) 6 Dec.2005 - 7 Jan.2006,and (ii) 22 Dec.2006 – 8 Jan 2007).An Aethelometer has been installed at the KSJ to monitor anthropogenic black carbon since 22 December 2006.Time resolution of the CPC measurements was set as 1 second to detect nano-meter size particle formation.The OPC measured particle number size distribution for 32 channels ranging from 0.3 μm to 20 μm with a time resolution of 5 minutes.Meteorological data,such as solar irradiance,air temperature,wind speeds and direction,atmospheric pressure,were obtained from the KSJ meteorological observation tower.

碳酸盐岩缝洞型油藏非均质性强,目前制约缝洞型油藏高效开发的主要难点是缝洞储层的连通性识别.本文以塔北Y地区为例,地质-物探-油藏多学科相结合,形成了一套静态描述、动态验证、迭代调整的储层连通性分析技术.该套技术从碳酸盐岩缝洞型储集体的地球物理响应特征分析出发,预测出孔洞地震属性体和裂缝地震属性体,对不同地震体进行网格化运算,根据网格化后晶格间的接触关系,判断地震体间的连通性,并将生产动态特征与储层
大庆喇嘛甸油田SⅡ油层组主要发育河流-三角洲沉积体系,河流发育,具有"同期平面多变性、垂向多期河道切割叠置性"等特点,等时对比具有一定的难度.本文依据"重点井沉积时间单元划分"－"标准层控制﹑参照层借鉴对比"－"平面井网对比"这一方法,对研究区301口开发井进行了精细划分、对比,在此基础上,通过测井微相模式的建立和沉积微相的研究,精细刻画了各沉积时间单元砂体空间分布规律,实现了单一河道砂体的识别,
Considering its size and potential importance,the ocean is surprisingly poorly characterised in terms of organic gases that play important roles in global atmospheric chemistry.In this project we aim
The ocean’s influence on volatile organic compounds (VOCs) in the atmosphere is poorly understood.This work characterises the oceanic emission and / or uptake of methanol,acetone,acetaldehyde,isoprene
Carbon monoxide (CO) and non-methane hydrocarbons (NMHC) are naturally produced from the ocean surface and this oceanic source,which can have an impact on the remote atmospheric chemistry,needs to be
The flux of DMS from the ocean to the atmosphere plays a major role in the marine atmospheric sulfur cycle.The oxidation of this biogenic sulfur to SO2 and subsequently to sulfate aerosol (which can a
We carried out experiments to evaluate the impacts of UV radiation (UVR,280-400nm) on photosynthetic carbon fixation of phytoplankton assemblages from coastal waters of the South China Sea during Marc
The importance and research progress in the estimation of sea-air fluxes of CO2 using remote sensing data in the recent years have been reviewed in this paper.Carbon flux estimation was based on the e
The distributions of dimethylsulfide (DMS) as well as particulate and dissolved fractions of dimethylsulfoniopropionate (DMSPp and DMSPd) were examined in the sea-surface microlayer (SML) and correspo
The atmosphere is widely recognized as a major source of Fe in the form of iron-containing dust.We sampled ten dusts from strong dust storm source regions and one dust from coastland Qingdao.This stud
