Abstract. With the rapid development of economy, sulfur dioxide (SO2) emission from China since 2000 is increasing concern. In this study, we estimate annual SO2 in after using a technology-based methodology specifically for China. From to 2006, total increased by 53%, 21.7 Tg 33.2 Tg, at an growth rate 7.3%. Emissions power plants are main sources and they 10.6 18.6 same period. Geographically, north 85%, whereas that south only 28%. The slowed around 2005, emissions began decrease 2006...
Abstract. Aerosol variations and trends over different land ocean regions from 1980 to 2009 are analyzed with the Goddard Chemistry Radiation Transport (GOCART) model observations multiple satellite sensors available ground-based networks. Excluding time periods large volcanic influence, aerosol optical depth (AOD) surface concentration polluted generally vary anthropogenic emissions, but magnitude of this association can be dampened by presence natural aerosols, especially dust. Over...
Abstract. The Maritime Aerosol Network (MAN) has been collecting data over the oceans since November 2006. Over 80 cruises were completed through early 2010 with deployments continuing. Measurement areas included various parts of Atlantic Ocean, Northern and Southern Pacific South Indian Arctic Ocean inland seas. MAN deploys Microtops hand-held sunphotometers utilizes a calibration procedure processing traceable to AERONET. Data collection that previously had no aerosol optical depth (AOD)...
Abstract. The land surface plays a crucial role in regulating water and energy fluxes at the land–atmosphere (L–A) interface controls many processes feedbacks climate system. Land cover vegetation type remains one key determinant of soil moisture content that impacts air temperature, planetary boundary layer (PBL) evolution, precipitation through soil-moisture–evapotranspiration coupling. In turn, it will affect atmospheric chemistry quality. This paper presents results modeling study effect...
Increasing bandwidth demands of mobile video streaming pose a challenge in optimizing the Quality Experience (QoE) for better user engagement. Multipath transmission promises to extend network capacity by utilizing multiple wireless links simultaneously. Previous studies mainly tune packet scheduler multipath transmission, expecting higher QoE accelerating transmission. However, since Adaptive BitRate (ABR) algorithms overlook impact scheduling on throughput prediction, adaptive can even...
Increasing bandwidth demands of mobile video streaming pose a challenge in optimizing the Quality Experience (QoE) for better user engagement. Multipath transmission promises to extend network capacity by utilizing multiple wireless links simultaneously. Previous studies mainly tune packet scheduler multipath transmission, expecting higher QoE accelerating transmission. However, because application-layer Adaptive BitRate (ABR) algorithms are inherently uncoordinated with scheduling transport...

In real-time communication (RTC) systems, accurate bandwidth prediction is crucial for encoding and transmission strategies to optimize users' quality of experience (QoE) in various network environments. this paper, we propose an offline reinforcement learning (RL) method predict RTC video streaming. We use a representative algorithm, named Implicit Q-Learning (IQL), train the model. To improve performance, carefully preprocess given dataset redesign neural structure reward function....

Video streaming is the most important mobile application today. To improve users' quality of experience (QoE), client player runs adaptive bitrate (ABR) algorithms that dynamically select for video chunks based on throughput or delivery time predictions. This paper aims to design an accurate predictor by investigating all its components, including input features, output target, and mapping function. We construct first theoretical framework reveals potential factors affecting chunk time....
