A handful of nice grinding surface pictures I discovered:
Satellite Image Shows the Snow-covered U.S. Deep Freeze

NOAA’s GOES-East satellite offered a appear at the frigid eastern two-thirds of the U.S. on Jan. 7, 2015, that shows a blanket of northern snow, lake-effect snow from the Excellent Lakes and clouds behind the Arctic cold front.
A visible picture captured at 1600 UTC (11 a.m. EST) showed the effects of the most current Arctic outbreak. The cold front that brought the Arctic air has moved as far south as Florida, and stretches back over the Gulf of Mexico and just west of Texas today. The image shows clouds behind the frontal boundary stretching from the Carolinas west more than the Heartland. Farther north, a wide band of fallen snow covers the ground from New England west to Montana, with rivers appearing like veins. The GOES-East satellite image also shows wind-whipped lake-impact snows off the Wonderful Lakes, blowing to the southeast. Meanwhile, Florida, the nation’s warm spot appeared virtually cloud-totally free.
To produce the image, NASA/NOAA’s GOES Project employed cloud data from NOAA’s GOES-East satellite and overlaid it on a correct-colour image of land and ocean produced by data from the Moderate Resolution Imaging Spectroradiometer, or MODIS, instrument that flies aboard NASA’s Aqua and Terra satellites. Collectively, those information developed the whole picture of the Arctic outbreak.
The forecast from NOAA’s National Weather Service Weather Prediction Center (WPC) calls for a lot more snow along the Appalachian Mountains from Tennessee north to upstate New York. Snow is also expected to fall from New England west to Montana, and in eastern New Mexico and the Colorado Rockies. The WPC summary for Jan. 7 noted: Bitter cold will be felt from the western High Plains to the Mid-Atlantic and Northeast U.S. for the subsequent few days. Widespread subzero overnight lows are forecast for the Dakotas, Upper Midwest, Fantastic Lakes, and interior New England. Wind Chill Advisories and Warnings are in effect for numerous of these areas.
GOES-East offers visible and infrared photos more than the eastern U.S. and the Atlantic Ocean from its fixed orbit in space. NOAA’s GOES satellites give the sort of continuous monitoring required for intensive information analysis. Geostationary describes an orbit in which a satellite is constantly in the exact same position with respect to the rotating Earth. This enables GOES to hover continuously more than one particular position on Earth’s surface, appearing stationary. As a outcome, GOES provide a continual vigil for the atmospheric triggers for serious climate situations such as tornadoes, flash floods, hail storms and hurricanes.

City Lights of the United States 2012
Image by NASA Goddard Photo and Video
NASA image acquired April 18 – October 23, 2012
This image of the United States of America at evening is a composite assembled from information acquired by the Suomi NPP satellite in April and October 2012. The image was produced possible by the new satellite’s “day-evening band” of the Visible Infrared Imaging Radiometer Suite (VIIRS), which detects light in a range of wavelengths from green to near-infrared and makes use of filtering tactics to observe dim signals such as city lights, gas flares, auroras, wildfires, and reflected moonlight.
“Nighttime light is the most interesting information that I’ve had a opportunity to operate with,” says Chris Elvidge, who leads the Earth Observation Group at NOAA’s National Geophysical Information Center. “I’m often amazed at what city light photos show us about human activity.” His research group has been approached by scientists looking for to model the distribution of carbon dioxide emissions from fossil fuels and to monitor the activity of industrial fishing fleets. Biologists have examined how urban development has fragmented animal habitat. Elvidge even learned once of a study of dictatorships in numerous parts of the world and how nighttime lights had a tendency to expand in the dictator’s hometown or province.
Named for satellite meteorology pioneer Verner Suomi, NPP flies more than any offered point on Earth’s surface twice each day at roughly 1:30 a.m. and p.m. The polar-orbiting satellite flies 824 kilometers (512 miles) above the surface, sending its data after per orbit to a ground station in Svalbard, Norway, and continuously to local direct broadcast users distributed about the globe. Suomi NPP is managed by NASA with operational help from NOAA and its Joint Polar Satellite System, which manages the satellite’s ground technique.

Preparing For Antarctic Flights in the California Desert
Image by NASA Goddard Space Flight Center
At first glance a dry lake bed in the southern California desert appears like the last place to prepare to study ice. But on Oct. two, 2014, NASA’s Operation IceBridge carried out a ground-primarily based GPS survey of the El Mirage lake bed in California’s Mojave Desert. Members of the IceBridge group are at the moment at NASA’s Armstrong Flight Investigation Center, preparing instruments aboard the DC-8 study aircraft for flights more than Antarctica.
Element of this preparation includes test flights more than the desert, exactly where researchers verify their instruments are operating effectively. El Mirage serves as a prime place for testing the mission’s laser altimeter, the Airborne Topographic Mapper, due to the fact the lake bed has a flat surface and reflects light similarly to snow and ice.
This photo, taken shortly right after the survey, shows the GPS-equipped survey car and a stationary GPS station (left of the car) on the lake bed with the constellation Ursa Major in the background. By driving the vehicle in parallel back and forth lines more than a predefined region and comparing these GPS elevation readings with measurements from the stationary GPS, researchers are in a position to create an elevation map that will be used to precisely calibrate the laser altimeter for ice measurements.

Operation IceBridge is scheduled to start investigation flights more than Antarctica on Oct. 15, 2014. The mission will be primarily based out of Punta Arenas, Chile, till Nov. 23.
