Assessment of the CALIPSO Lidar 532 nm attenuated backscatter calibration using the NASA LaRC airborne High Spectral Resolution Lidar
the CALIPSO Lidar 532 nm backscatter calibration the NASA LaRC airborne High Spectral Resolution Lidar
2011/2/25
This paper presents a quantitative assessment of the CALIOP 532 nm calibration (through the 532 nm total attenuated backscatter) using internally calibrated airborne HSRL underflight data and is the m...
A new inventory of air pollutant emissions in Asia in the year 2006 is developed to support the Intercontinental Chemical Transport Experiment-Phase B (INTEX-B) funded by the National Aeronautics and ...

In the most comprehensive survey ever undertaken of the massive ice sheets covering both Greenland and Antarctica, NASA scientists confirm climate warming is changing how much water remains locked in ...
NASA关注冰里生存蠕虫 望揭开低温星球生命之迷
2008/1/18
蠕虫通常来说是钓鱼者的饲料或早起的鸟儿的盘中餐。而现在它们却引起了美国国家航空航天局的重视。特别是某个生活在低温环境中物种，它们可以完全不进食而存活两年。研究人员希望通过对这种小蠕虫在低温中生存能力的研究来解开一些科学难题，比如表面具厚达100公里固态水的木卫二，可能存在生命的秘密，同时还能回答一些如何冷冻保存移植器官的实际问题。美国宇航局NASA最近向拉杰.卡姆登大学（Rutgers-Camde...
NASA科学家解释空气污染对气候的影响
空气污染
2008/1/18
NASA的科学家最近在Science杂志在线版上撰文，解释了空气污染对气候影响这一长期让人感到迷惑的问题。空气污染和烟尘带来的大气气溶胶在一些情况下会阻止云的生成，而在另外的情形下则加速云层变厚。而云不仅在全球范围内运送水气，还会控制太阳到达地球热量的多少。科学家们认为，在这一过程中，空气污染吸收太阳能量的能力是关键所在。当气溶胶粒子的混合使得受到污染的空气吸收更多的太阳辐射时，会阻止云的生成。而...
