Summary
Abstract: One of the key components of NASAs Earth Science
Research Strategy to better understand the complex nature of Earths
climate is the determination of the global radiation balance.
Comprehensive regional-to-global climate models (R/GCM) are playing an
ever-greater role in addressing this issue. Because of their important
role in modifying the radiative energy balance, the characteristics of
aerosols, especially near their sources and sinks, are essential
parameters to the R/GCMs. Many EOS era instruments (e.g., SeaWiFS,
MODIS, MISR, etc.) are designed to provide such information with a high
degree of fidelity. A README can be found at
