台湾集集强震前的卫星遥感长波辐射场变异分析

1999年9月21日我国台湾省集集发生7.6级强烈破坏性地震。对这次强震的发生,应用NOAA卫星遥感监测“地-气系统”射出长波辐射-OLR场的数据进行分析后发现,强震前至强震时,震央所在地域显示有长波辐射增强的变异特征,可能与强震孕育过程中的热状态有关。识别和提取卫星对地遥感红外波段的热兆信息,可望在监视预报强震发生地域上开创出新的技术途径。

Retrieval of Atmospheric Horizontal Visibility by Statistical Regression from NOAA/AVHRR Satellite Data

Based on the atmospheric horizontal visibility data from forty-seven observational stations along the eastern coast of China near the Taiwan Strait and simultaneous NOAA/AVHRR multichannel satellite data during January 2001 to December 2002, the spectral characters associated with visibility were investigated. Successful retrieval of visibility from multichannel NOAA/AVHRR data was performed using the principal component regression （PCR） method. A sample of retrieved visibility distribution was discussed with a sea fog process. The correlation coefficient between the observed and retrieved visibility was about 0.82, which is far higher than the 99.9% confidence level by statistical test. The rate of successful retrieval is 94.98% of the 458 cases during 2001 2002. The error distribution showed that high visibilities were usually under-estimated and low visibilities were over-estimated and the relative error between the observed and retrieved visibilities was about 21.4%.     

基于GNSS-IR双系统组合的土壤湿度多星线性回归反演模型

提出一种GPS/BDS双系统组合的土壤湿度多星线性回归反演模型,并以GNSS接收机实测数据为例,对比分析不同GPS和BDS卫星组合反演土壤湿度的效果。实验表明：1)GPS和BDS双系统组合相对于单系统在短观测时间内可以提高有效卫星数,通过多元线性回归原理可实现双系统多卫星的有效融合,提高土壤湿度反演的精度;2)当GPS和BDS组合卫星数达到6颗以上时,反演效果趋于稳定,反演结果与土壤湿度的相关系数均优于0.90,RMSE相对于单星至少提高25.8%。     

Satellite monitoring of sea surface temperatures off China

Satellite measurements of global sea surface temperatures (SST) have been made since 1982 using the multi-channel radiometers (AVHRR) on NOAA polar orbiting satellites. A four year data set was accumulated at daily intervals and a spatial resolution of about 100 kilometers on an interactive computer system. The time lapse evaluation of the data revealed variations of the SST which were related to coastal and equatorial upwelling events as well as to the pronounced equatorial warming associated with the 1982–1983 El Niño. In the present study, satellite time series are used to describe the annual variability of the SST at selected locations along the coast of China, the Yellow Sea, the Sea of Japan and the Equatorial Indian and Pacific Oceans. Further study of the SST off China using higher resolution satellite data are also described.
