The results of their study from the 2009 NASA Student Airborne Research Program are published in the Aug. 4 online edition of the journal Remote Sensing Letters, (http://www.tandfonline.com/doi/abs/10.1080/01431161.2010.551550).
In brief, the students from Howard University and Georgia Institute of Technology flew over Southern California aboard NASA's DC-8 airborne science laboratory and operated NASA's MODIS and ASTER remote sensing instruments. The flight was guided by forecasts from the UI Center for Global and Regional Environmental Research (CGRER).
When processing the images they collected, the students found that using CGRER's regional model forecasts for local weather and air quality substantially improved sea surface temperature measurements and also increased the sensitivity of measurements over cities and areas covered by vegetation.
Using CGRER model results was found to be an improvement over standard approaches to calculating surface measurements from satellite images, which incorporate a one-size-fits-all average for weather and trace gas concentrations.
"This new approach can help improve the global satellite record of the Earth's surface and oceans, by taking better daily snapshots of how human activity affects them over time," Spak said. "This one change can improve our ability to accurately track a wide range of environmental questions, including urban heat islands, coastal algae blooms and the regrowth of deforested areas."
Spak and CGRER Co-director Greg Carmichael are working with NASA to apply the technique to improve satellite air pollution estimates.
Spak is an assistant professor with joint appointments in the UI Public Policy Center, School of Urban and Regional Planning, and the UI College of Engineering Department of Civil and Environmental Engineering.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
