Aerosol Properties Over Bright-Reflecting Source Regions
April 25, 2004 —
A new satellite algorithm has been developed to retrieve aerosol optical thickness (AOT) and single scattering albedo over bright-reflecting surfaces such as urban areas and deserts. Such retrievals have been difficult to perform using previously availabl . . . [continued]

MODIS Optical Thickness and Effective Particle Radius Uncertainties
April 18, 2004 —
An example uncertainty for stratocumulus clouds off the coasts of Peru/Chile is shown for a MODIS Terra data granule on 18 July 2001 (thin cirrus to the south and convective ice clouds in the Amazon basin are also found). The true color composite is shown . . . [continued]

Spatial Distribution of Large Cloud Drops
April 11, 2004 —
This image illustrates the different space-filling properties of large (black) and small (gray) cloud drop distributions. There are an equal number (5115) of drops colored gray and black. The gray drops are distributed randomly throughout the space whe . . . [continued]

Higher Warm Rain Efficiency in a Warmer World
April 4, 2004 —
As the tropical oceans continue to heat up, following a 20-year trend, the water cycle in the tropics is likely to accelerate, according to a new paper published in the journal Geophysical Research Letters. In this study by Bill Lau and Jenny Wu, t . . . [continued]
