    Therefore, since aerosols affect satellite imagery of the earth's surface, attempts for its correction should be taken. Satellite images of the Earth's surface in the solar spectrum are contaminated by sunlight scattered towards the sensor by atmospheric molecules, aerosols, and clouds (path radiance).File Size: 4MB. estimation using MODIS nighttime LST. As a result, the present study reveals the effects of clouds on Tmax and Tmin estimation through MODIS daytime and nighttime LST, re-spectively, so as to help improve the Tair estimation accuracy and alleviate the severe air temperature data sparseness issues over the TP. 1 IntroductionCited by: A time series of satellite images confirms that in and early China constructed for military training purposes a building that closely resembles Taiwan’s Presidential Office Building in.   Over the course of weeks, the water built up behind the glacier, until the ice floated up on top of the water, and the river broke free.

Except for TRMM, satellite-based precipitation retrieval techniques perform poorly in complex terrain, because low-level, topographically forced updrafts may trigger heavy instance, the annual rainfall on Mt Waialeale on the island of Kauai, Hawai'i, is nearly 10 m, yet the cloud tops rarely are above ° C.
