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.
