Recently, a growing interest has been seen in deep learning-based semantic segmentation. UNet, which is one of learning networks with an encoder-decoder architecture, widely used medical image Combining multi-scale features important factors for accurate UNet++ was developed as modified Unet by designing architecture nested and dense skip connections. However, it does not explore sufficient information from full scales there still large room improvement. In this paper, we propose novel UNet...
Abstract Statistical downscaling and dynamical are two approaches to generate high‐resolution regional climate models based on the large‐scale information from either reanalysis data or global models. In this study, these methods used simulate surface of China compared. The Downscaling Model (SDSM) is cross validated downscale China. Then, downscaled historical 1981–2000 future 2041–2060 compared with that Weather Research Forecasting (WRF) model driven by European Center‐Hamburg atmosphere...
Changes in terrestrial near-surface wind speed (SWS) are induced by a combination of anthropogenic activities and natural climate changes. Thus, the study long-term changes SWS their causes is very important for recognizing effects these processes. Although slowdown has been analyzed previous studies, to best knowledge, no overall comparison or detailed examination this research performed. Similarly, decreases directions future have not discussed depth. Therefore, we series studies reporting...
The accelerating development of autonomous driving technology has placed greater demands on obtaining large amounts high-quality data. Representative, labeled, real world data serves as the fuel for training deep learning networks, critical improving self-driving perception algorithms. In this paper, we introduce PandaSet, first dataset produced by a complete, high-precision vehicle sensor kit with no-cost commercial license. was collected using one 360° mechanical spinning LiDAR,...
Abstract Based on the daily maximum temperatures ( T max ) from 587 surface observation stations in China during 1959–2013, heat waves are detected using both absolute and relative definitions. The spatiotemporal variations of wave occurrence/duration/amplitude compared between two Considering significant differences regional climatology, threshold is more meaningful to detect local extremes. By utilizing empirical orthogonal function, integral index total intensity decomposed into three...
Biomass burning (BB) has significant impacts on air quality, climate and human health. In China, the BB emission changed substantially over past decades while multi-year variation held high uncertainty driving forces have addressed little attention. Here, this research aimed to conduct a comprehensive systematic analysis of in China provided precise targeted reduction suggestions. The moving for from 2003 2014 was clearly identified, by view reliable estimation anthropogenic impacts....
Abstract. Open biomass burning (OBB) has significant impacts on air pollution, climate change and potential human health. OBB gathered wide attention but with little focus the annual variation of pollutant emission. Central eastern China (CEC) is one most polluted regions in China. This study aims to provide a state-of-the-art estimation emissions from CEC 2003 2015, by adopting satellite observation dataset – burned area product (MCD64Al) active fire (MCD14 ML) along local data (updated...
Levoglucosan (LG) emitted from non-biomass burning (non-BB) sources has given rise to biased or even unreasonable source identification results when adopting LG as a distinct marker of biomass (BB). The estimation emission and its spatiotemporal variation for various are the keys reducing uncertainty. This study first developed inventory China 25 sub-type belonging eight categories, with 3 km × spatial resolution monthly distribution. total in 2014 was 145.7 Gg. Domestic BB open contributed...
The long-term decrease of surface wind speed (SWS) has been revealed by previous studies in China recent decades, but the reasons for SWS remain uncertain. In this paper, we evaluated effects land use and cover change (LUCC) on during 1980–2011 over Eastern Plain (ECP) region using a combined method statistical downscaling observation minus reanalysis data, which was used to improve climate prediction general circulation models evaluate influence LUCC change. To exclude potential...
Abstract. Black carbon (BC), which is formed from the incomplete combustion of fuel sources (mainly fossil fuel, biofuel and open biomass burning), a chemically inert optical absorber in atmosphere. It has significant impacts on global climate, regional air quality human health. During transportation, its physical chemical characteristics as well change dramatically. To investigate properties BC (i.e., mass concentration, properties) during intra-regional transport between southern edge...
Abstract Horizontal visibility and water vapor pressure data from 483 stations in China 1960 to 2009 were used inverse aerosol optical depth (AOD) using a new series of parameters, which revised for each station the polybasic nonlinear regression method based on monthly Multiangle Imaging Spectroradiometer (MISR) AOD during 2001–2005. Monthly retrievals 2006 parameters compared with MISR same period. retrieved can capture extreme values better than inversion result original root‐mean‐square...
Abstract A recovery of near-surface wind speed (SWS) in the last decade has been reported over China; nevertheless, contributions large-scale ocean-atmosphere circulations (LOACs) to SWS changes are rarely investigated. In this study, turning point (TP) terrestrial stilling was validated eastern China for 1979–2017. Furthermore, a forward stepwise regression algorithm used assess contribution LOACs changes. The results revealed that TP reversal occurred approximately 2011 during study...
Abstract Near‐surface wind speed (NSWS) over China shows multiple time‐scale changes at a centennial scale, but the contributions of internal variability (IV), anthropogenic forcing (ANT), and natural (NAT) to those remain unknown. This study investigated IV, ANT, NAT NSWS scale. Results show that were attributed mainly IV. IV not only modulated interannual in also determined interdecadal transition NSWS. The relative decadal exceeded 75.0%. ANT contributed particularly long‐term reduction...
The changes of near-surface wind speed (SWS) were induced by the combination effects from anthropogenic activities and natural climate changes, thus research long-term cause SWS is very important to recognize SWS. Some studies have shown that land use cover change (LUCC) over China was distinct in last 30 years. However, possible LUCC slowdown are still uncertain. European Centre for Medium-Range Weather Forecasts Reanalysis January 1989 onward (to be extended back 1979) (ERA-Interim...
DeepFake can forge high-quality tampered images and videos that are consistent with the distribution of real data. Its rapid development causes people's panic reflection. In this paper we presents an improved VGG network named NA-VGG to detect face image, which was based on image noise augmentation. Firstly, order learn tampering artifacts may not be seen in RGB channels, SRM filter layer is used highlight features; Secondly, map augmented weaken features. Finally, input into train judge...
