一种新的卫星热红外遥感信息数据源:EOS/MODIS数据   总被引：4，自引：0，他引：4  

刘放  程万正  冉茂农 《国际地震动态》2003,(8):1-7

概略介绍了四川省地震局近年来所开展的卫星遥感热红外辐射信息用于地震监测预报的研究工作及其进展；对目前地震系统卫星遥感热红外辐射信息研究工作所使用的数据源进行了比较；着重介绍了一种新的卫星热红外遥感信息数据源——搭载于美国地球观测系统(EOS)的Terra和Aqua极轨卫星上的中分辨率成像光谱仪(MODIS)这一唯一进行直接广播的对地观测仪器的基本参数及数据特性。对MODIS数据与目前正在使用的AVHRR数据进行对比分析后认为，EOS／MODIS数据的产生，将进一步推动利用卫星热红外辐射资料研究强震前的热异常场的工作，并可望在我国地震监测预报实践中得到应用。  相似文献

The first ISPRS software contest for computer-assisted teaching (CATCON)     

Kohei Cho 《ISPRS Journal of Photogrammetry and Remote Sensing》1997,52(6):277-280

The first ISPRS software contest for computer-assisted teaching, CATCON, took place on July 12, 1996 at the ISPRS Congress in Vienna. The main objective of the contest was to promote the development and dissemination of good/user-friendly software packages for computer-assisted teaching. Ten software packages and one data set from six countries were nominated. All the software and the data set were demonstrated at the contest, and prizes were given to three software packages and to one data set.  相似文献   

Internet teaching foundation for the Remote Sensing Core Curriculum program     

T.W. Foresman  T. Cary  T. Shupin  R. Eastman  J.E. Estes  N. Faust  J.R. Jensen  K.K. Kemp 《ISPRS Journal of Photogrammetry and Remote Sensing》1997,52(6):294-300

The Remote Sensing Core Curriculum (RSCC) was initiated in 1993 to meet the demands for a college-level set of resources to enhance the quality of education across national and international campuses. The American Society of Photogrammetry and Remote Sensing adopted the RSCC in 1996 to sustain support of this educational initiative for its membership and collegiate community. A series of volumes, containing lectures, exercises, and data, is being created by expert contributors to address the different technical fields of remote sensing. The RSCC program is designed to operate on the Internet taking full advantage of the World Wide Web (WWW) technology for distance learning. The issues of curriculum development related to the educational setting, with demands on faculty, students, and facilities, is considered to understand the new paradigms for WW-influenced computer-aided learning. The WWW is shown to be especially appropriate for facilitating remote sensing education with requirements for addressing image data sets and multimedia learning tools. The RSCC is located at http://www.umbc.edu/rscc  相似文献   

Column Amounts of ClONO2, HCl, HNO3, and HF from Ground-Based FTIR Measurements Made Near Kiruna, Sweden, in Late Winter 1994     

TH. Blumenstock  H. Fisher  A. Friedle  F. Hase  P. Thomas 《Journal of Atmospheric Chemistry》1997,26(3):311-321

During SESAME phase I ground-based FTIR measurements were performed atEsrange near Kiruna, Sweden, from 28 January to 26 March 1994. Zenith columnamounts of ClONO₂, HCl, HF, HNO₃,O₃, N₂O, CH₄, and CFC-12 werederived from solar absorption spectra. Time series of ClONO₂and HCl indicate a chlorine activation at the end of January and around 1March. On 1 March a very low amount of HCl of 2.09times; 10¹⁵molec. cm^-2 was detected, probably caused by a second chlorineactivation phase starting from an already decreased amount of HCl. The ratioof column amounts of HCl to ClONO₂ decreased inside the vortexfrom about 1 in January to 0.4 in late March compared to values of about 2outside the vortex. Although the Arctic stratosphere was rather warm in winter1993/94 and PSCs occurred seldom, chlorine partitioning into its reservoirspecies HCl and ClONO₂ changed during that winter andClONO₂ is the major chlorine reservoir at the end of thewinter as in cold winters like 1991/92 and 1994/95.  相似文献
