NASA satellite data are giving scientists insight into how large-scale deforestation in the Amazon Basin in South America is affecting regional climate. Researchers found during the Amazon dry season last August, there was a distinct pattern of higher rainfall and warmer temperatures over deforested regions.
LOOKING AT DEFORESTATION BY SATELLITE
This black and white image was created from the visible channel of the Geosynchronous Operational Environmental Satellite (GOES). Deforestated areas are depicted in gray and white shading over Rondonia, Brazil. The lighter shaded area around Porto Velho is a naturally occurring region of savanna and the urban area.

COMPARING THE SIZE OF RONDONIAS DEFORESTATION TO FLORIDA

Researchers analyzed multiple years of data from NASAs Tropical Rainfall Measuring Mission (TRMM). They also used data from the Department of Defense Special Sensor Microwave Imager and the National Oceanic and Atmospheric Administrations Geostationary Operational Environmental Satellites.
The study appeared in a recent issue of the American Meteorological Societys Journal of Climate. Lead authors, Andrew Negri and Robert Adler, are research meteorologists at NASAs Goddard Space Flight Center (GSFC), Greenbelt, Md. Other authors include Liming Xu, formerly of the University of Arizona, Tucson, and Jason Surratt, North Carolina State University, Raleigh.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
