中国东北农村地区,春秋季节由于秸秆的大量焚烧,大气悬浮颗粒物含量明显升高,PM10和PM2.5可以升高0.5至4倍。露天生物质燃烧(Open-air biomass burning,OBB)是微量气体污染物和细小碳质颗粒物(particulate matter,PM)的主要排放源。大面积、高强度的露天焚烧秸秆会对区域的空气质量以及当地的公共卫生安全造成损害。秸秆燃烧检测主要是靠检测秸秆焚烧的产物来...
湖泊变化是气候变化的指示器.为探索利用单一短时间尺度的卫星水位数据源估算长时间序列的湖泊水量变化的可行性,本文利用短时间尺度(2016—2018年) Sentinel-3A合成孔径雷达高度计(SRAL)作为唯一卫星水位数据源,以藏北高原内陆湖泊当惹雍错为例,结合基于Landsat光学遥感数据提取的1988—2018年的湖泊面积,综合分析2016—2018年间的非结冰期遥感湖泊面积与遥感湖泊水位变化...
SMAP project released a new enhanced high-resolution (3km) soil moisture active-passive product. This product is obtained by combining the SMAP radiometer data and the Sentinel-1A and -1B Synthetic Ap...
In this paper, we used the Generic Atmospheric Correction Online Service for InSAR (GACOS) tropospheric delay maps to correct the atmospheric phase delay of the differential interferometric synthetic ...
Synthetic Aperture Radar (SAR) can provide all-day and all-night observation of the earth in all-weather conditions with high resolution, and it is widely used in polar research including sea ice, sea...
The repeat-pass Synthetic Aperture Radio Detection and Ranging (RADAR) Interferometry (InSAR) has been a widely used geodetic technique for observing the Earth’s surface, especially for mapping the Ea...
On August 8, 2017, an earthquake of M 7.0 occurred at Jiuzhaigou. Based on the Sentinel-1 satellite InSAR data, we obtained coseismic deformation field and inverted the source slip model. Result...
Permanent pastures (PP) are defined as grasslands, which are not subjected to any tillage, but only to natural growth. They are important for local economies in the production of fodder and pastures (...
Land cover is a fundamental variable for regional planning, as well as for the study and understanding of the environment. This work propose a multi-temporal approach relying on a fusion of radar mult...
As any supervised classification procedure, also Local Climate Zone (LCZ) mapping requires reliable reference data. These are usually created manually and inevitably include label noise, caused by the...
SAFETY is a two-years European project started the 1st January 2016 and ended the 1st January 2018. The general aim of the project was to develop a methodology and tools in order to exploit Sentinel-1...

文中以Sentinel-1A升、降轨为数据源,利用"二轨法"获取门源地震的同震形变场,结果显示门源地震以抬升形变为主,其抬升形变值明显大于沉降形变值,升、降轨抬升区最大视线向形变分别为6cm、8cm。同时基于Okada位错模型,构建不同倾向断层模型,以升、降轨形变场数据为约束联合反演得到此次地震的断层滑动分布及震源参数,最佳断层模型参数分别为:倾角43°,走向128°,平均滑动角85°,最大滑动量...
北京时间2016年8月24日9时36分(UTC: 2016-08-24 01:36:33),在意大利中部城市佩鲁贾附近发生Mw 6.2地震(42.714°N,13.172°E),震源深度10.0 km(USGS)。震后约1小时,于2016年8月24日10时33分翁布里亚大区(42.822°N   13.126°E)又发生Mw5.5地震,震源深度10.0 km(USGS)。意大利中部地区阿...
2014年8月24日,在美国加州旧金山海湾北部的纳帕地区发生了MW6.1地震.发震断层是西纳帕断裂系统中的一部分,但是该断层之前并未被足够重视.本文利用欧洲空间局最近发射成功并刚刚投入使用的Sentinel-1A卫星获取的第一对同震干涉像对(20140807-20140831),得到了该地震的地表同震形变场,结合震后24 h内区域GPS同震形变资料作为约束条件,反演了纳帕地震的断层几何参数以及滑动...
