cloud cover

基本解释

Although the wind was still howling, the couple could hear airplanes flying somewhere over the cloud cover-one every 50 minutes or so.
虽然狂风仍在呼啸，夫妇俩却听见了飞机从云层之上穿过的声音，大概每50分钟就有一架。
The estimation of cloud-cover is mainly affected by the visibility of the day. Comparing the calculated results from about 350 images to the observation, the average error is about 10%.
结果分析表明，云量的计算结果受能见度影响程度大，晴好天气下云量的计算同观测员记录比较误差在10％左右。
It uses a high precision digital phase-locked loop(PLL) to accurately recover the Synchronous reference information of raw cloud-cover image data collected by the geostationary satellite.
它用高精度数字锁相环，精确地恢复地球同步气象卫星采集的原始云图数据的同步基准信息。

Less ice on rivers, lakes and the sea will lead to more evaporation, probably increasing cloud cover at mid-levels, which should have a cooling effect.
ECONOMIST: The science
Svensmark then teamed up with Friis-Christensen to review solar activity, cloud cover and cosmic ray levels recorded using satellite data available since 1979.
FORBES: Sorry, But With Global Warming It's The Sun, Stupid
His (as yet unpublished) research confirms, he says, that the variations in cloud cover seen by satellites match those in cosmic-ray flux better than anything else, such as the sun's total brightness.
ECONOMIST: Global warming: In flux

云覆盖
Cloud cover noise often occurs in remote sense image processing. It is a very important task to remove the effects of cloud cover.
遥感图像的薄云和雾霭覆盖是遥感图像处理中最常遇到的一种情况，有效的去除云覆盖的影响是遥感图像预处理阶段的重要任务。
