Satellite information explains North Pole shifting

Greenland's ice sheet captured by a satellite

Climate change is causing the North Pole’s location to drift, shows a new study conducted by Jianli Chen at the University of Texas at Austin. The explanation is in the small changes in Earth’s rotation due to global warming effects.

Computer simulations based on satellite information predict that the melting of the ice is causing a new allocation of mass on the planet’s surface and therefore a shifting of the Earth’s axis.

Remote Sensing helps locate the Coldest Spot on Earth

Remote Sensing image showsing the coldest place on Earth

NASA's Landsat 8 satellite defined the coldest place on Earth - a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius) on a clear winter night.

Scientists from NASA evaluated 21 years’ worth of data, including the most detailed global surface temperature maps, developed with data from remote sensing satellites. They found that the temperatures were record low many times between Dome Argus and Dome Fuji, but the new record was set on 10 August 2010.

NASA: App that shows climate change consequences

Pedersen Glacier 1917 and 2005

The impact of climate change on the environment is not always easy to see. Now, with NASA’s Images of Change iPad application, users can get an interactive before-and-after view of the changes.

The App is showing two images next to each other, showing the same region, that have been affected by the global climate change, disasters, global warming or a human activity.

Using space technology to monitor flooding in Thailand

Severe flooding affected large stretches of Thailand’s Chao Phraya River

The South Asia region is especially prone to flooding. Annually, flooding takes hundred of lives and causes damages in tens of billions US dollars.

In a collaboration of NASA’s Jet Propulsion Laboratory and the Hydro and Agro Informatics Institute of Thailand, sensorweb technologies are being used to enhance monitoring of flooding especially in Thailand. This technique is used for detection, early warning and analysis of high resolution imagery.

The GPM satellite has arrived at its launch site in Japan

Satellite has arrived at its Japanese launch site

The GPM satellite, created to to measure the type and intensity of precipitation, has arrived at its launch site in Japan after a flight from NASA's Goddard Space flight Center in Maryland. The spacecraft's microwave imager and dual-frequency radar will measure the type and intensity of precipitation, peering inside clouds and studying everything from winter storms to hurricanes. The special focus of interest for scientists is to track cyclones as they move from the tropics to higher latitudes. This allows them to see how the storms evolve as they move through different climate zones.

Somalia affected by unusual tropical cyclone

Tropical Cyclone 3A is just the fifth storm to strike the country since 1966

Somalia experienced one of the deadliest tropical cyclones in its history when on November 10–11, 2013, Tropical Cyclone 3A moved over Puntland causing flash floods that according to news reports left more than 100 dead and destroyed hundreds of homes as well as thousands of livestock. It was estimated that Tropical Cyclone 3A would dump 100-200 millimeters (4-8 inches) of rain, with potentially higher amounts in some regions, which results impressive given that the average annual rainfall in Puntland ranges from less than 100 mm (4 inches) to 200 mm (8 inches).

Why Colorado’s wildfires are becoming more destructive

The 346 homes destroyed by the Waldo Canyon fire was situated in Mountain Shadow
Colorado Springs, the county’s largest city, has driven much of the growth.

Some wildfire experts state that the expansion of communities in Colorado’s Fire Zone during the last decades is an important factor to understand the increasing destruction caused by wildfires of the area. The six most destructive fires in Colorado prior to 2000 destroyed an average of 15 homes, according to the Colorado State Forest Service. However, in the last years Colorado’s wildfires have become increasingly destructive, with the Waldo Canyon fire of 2012 burning down 346 homes.

Cooperative Institute for Meteorological Satellite Studies / University of Wisconsin-Madison (CIMSS-WISC)

CIMSS is a Cooperative Institute formed through a Memorandum of Understanding between the University of Wisconsin-Madison (UW-Madison), the National Oceanic and Atmospheric Administration (NOAA), and the National Aeronautics and Space Administration (NASA), in 1980. Directed by Dr. Steve Ackerman, CIMSS operates as an institute within the Space Science and Engineering Center (SSEC). CIMSS scientists conduct research using remote sensing systems for meteorological and surface-based applications.

The CIMSS mission includes three goals:

Heatwaves: Scientist identify atmospheric wave pattern

NASA’s Clouds and the Earth's Radiant Energy System (CERES) sensor

Scientists of the National Center for Atmospheric Research (NCAR) have identified a distinctive atmospheric wave pattern high above the Northern Hemisphere that can foreshadow the emergence of summertime heat waves in the United States more than two weeks in advance. The study was conducted in cooperation with the U.S. Department of Energy, NASA, and the National Science Foundation (NSF), which is NCAR's sponsor. NASA scientists helped guide the project and are involved in broader research in this area.
