What is in the Air?
May 29, 2005 —
This figure shows some examples of aerosol particles collected on filters and analyzed under the scanning electron microscope in collaboration with the Institute of Physics of the University of Sao Paulo, Brazil. Generally, aerosols cover a broad range of . . . [continued]

Tracking the Movements and Evolution of Dust Plumes over Land from MODIS
May 22, 2005 —
When strong winds blow over the desert, mineral dust gets lifted from the surface and into the atmosphere. Since these airborne particles sometimes travel very far distances from their source regions, they can impact the environments along their transport . . . [continued]

SST Forcing of Rainfall and Vertical Velocity: An Insight Beyond Monthly and Seasonal Means
May 15, 2005 —
The question of remote versus local influence of sea-surface temperatures (SSTs) on the precipitation was researched using data from a recent 16-year long simulation with the fv-GCM using Goddard cloud physics parameterization. In this simulation, SSTs we . . . [continued]

Global Spectral Surface Albedo with Snow Cover
May 8, 2005 —
Spatially complete white-sky albedo at 0.86 µm from January 1-16, 2002 without (top) and with (bottom) overlaid snow albedo values. Snow albedo values are based on the MODIS-derived hemispherical snow albedo as a function of IGBP ecosystem classification . . . [continued]

Bidirectional Reflectance Functions for Various Types of Surfaces
May 1, 2005 —
The Cloud Absorption Radiometer (CAR) flying aboard the University of Washington aircraft has provided a convenient and efficient means of obtaining complete bidirectional reflectance distribution function (BRDF) for several surface types as shown in this . . . [continued]
