Therefore, vegetation index and brightness temperature can be used to monitor drought regime. 用植被指数和亮温可以估计土壤湿度情况,并对干旱进行监测。
Research on Extreme Weather and Climate Events using MSU and AMSU Brightness Temperature(BT) Data MSU及AMSU亮温资料在极端天气气候应用中的研究
The high brightness temperature of the pulsar radio emission implies that the underlying emission mechanism must be coherent. 极高的亮温度意味着起作用的发射机制一定是相干的。
The results show that vegetation index could reflect a part of moisture information, and there is some relationship between brightness temperature and soil moisture. 结果表明,农田土壤湿度与植被指数和亮温间均存在一定相关关系;
It is not always suitable to use Planck's law or Stefan-Boltzmann's law to describe the relation between brightness temperature and radiance for a wide band sensor. 对于宽波段传感器,不一定能直接由普朗克定律或者斯蒂芬玻尔兹曼定律建立温度与辐射亮度的关系。
