NASA unveils spectacular suite of new global data products
...IS allows scientists to measure the differences in cloud
optical properties for both water and ice clouds. The sensor can characterize the optical thickness of clouds and quantify the size of the particles within them. Moreover, MODIS is the first space-based sensor with a 1.37-m channel, which is particul...
