Italy earthquake occurrence models
2015/8/28
This study describes three earthquake occurrence models as applied to the whole Italian territory, to assess the occurrence probabilities of future (M ≥5.0) earthquakes: two as short-term (24 hour) mo...
Inflation of Aira Caldera (Japan) detected over Kokubu urban area using SAR interferometry ERS data
Inflation Aira Caldera Kokubu urban area SAR interferometry ERS data
2009/10/22
Nine ERS-1 and ERS-2 descending orbit data acquired over the Aira Caldera between June 1995 and November 1998 were used to create 31 differential interferograms. Although the interferograms exhibit a ...
An Assessment of the Capabilities of the ERS Satellites' Active Microwave Instruments for Monitoring Soil Moisture Change
European Remote sensing Monitoring Soil Moisture Change active microwave instrument
2009/6/8
The launch of the European Remote sensing Satellite (ERS-1) in July 1991 represented an important turning point in the development of Earth observation as it was the first of a series of satellites wh...
Analysis of surface and root-zone soil moisture dynamics with ERS scatterometer and the hydrometeorological model SAFRAN-ISBA-MODCOU at Grand Morin watershed (France)
soil moisture dynamics hydrometeorological model
2009/5/6
Spatial and temporal variations of soil moisture strongly affect flooding, erosion, solute transport and vegetation productivity. Its characterization, offers an avenue to improve our understanding of...
On the comparison between the LISFLOOD modelled and the ERS/SCAT derived soil moisture estimates
soil moisture estimates root mean square
2009/5/6
In order to evaluate the reliability of the soil moisture product obtained by means of the LISFLOOD hydrological model (De Roo et al., 2000), we compare it to soil moisture estimates derived from ERS ...
Matching ERS scatterometer based soil moisture patterns with simulations of a conceptual dual layer hydrologic model over Austria
soil moisture dual layer hydrologic model
2009/4/27
This study compares ERS scatterometer top soil moisture observations with simulations of a dual layer conceptual hydrologic model. The comparison is performed for 148 Austrian catchments in the period...
Global ozone forecasting based on ERS-2 GOME observations
Global ozone forecasting ERS-2 GOME
2009/3/12
The availability of near-real time ozone observations from satellite instruments has recently initiated the development of ozone data assimilation systems. In this paper we present the results of an o...
Internal Waves in the Strait of Messina Studied by a Numerical Model and Synthetic Aperture Radar Images from the ERS 1/2 Satellites
synthetic aperture radar Numerical Model ERS
2008/11/18
A new numerical two-layer model is presented, which describes the generation of internal tidal bores and their disintegration into internal solitary waves in the Strait of Messina. This model is used ...

SAR(Synthetic Aperture Radar)反演海洋风矢量是当今微波遥感领域非常有意义的前沿课题. 本文首先介绍了星载SAR估算海面风向、风速的基本原理和三种主流反演算法，接着给出反演的流程图以及重要步骤. 然后，以2002年5月7日香港地区ERS-2 SAR海洋图像为例，对经典的SWDA (SAR Wind Direction Algorithm)－谱分析方法加以改进，求得具有18...
由ERS-1波形重构确定我国近海平均海平面
星测高 平均海平面 波形重构 近海
2008/5/6
近海岸区域平均海面高在大地测量学、物理海洋学以及地球物理学研究中具有非常重要的意义.受各种条件的制约和限制，目前卫星测高技术主要应用于深海区域，在近海区域尤其是海岸线附近区域的应用几乎为空白.本文根据ERS-1测高卫星回波波形特征，采用五参数线性模型，由最小二乘拟合方法，对近海区域尤其是靠近海岸线附近的ERS-1测高波形数据进行波形重构.比较波形重构前、后解算平均海面高，表明波形重构技术不仅明显改...
摘要：
运用反向PCR（IPCR）技术首次克隆得到全长为3 506 bp的中华绒螯蟹（Eriocheir japonica sinensis）蜕皮抑制激素 1（MIH 1）基因组DNA序列（GenBank检索号：AY310313）。该序列包括3个外显子、2个内含子、412 bp的5' 端上游调控区和917 bp的3' 端UTR。编码区的第1个内含子将信号肽分开，第2个内含子将成熟肽分开。MIH 1...
