When Typhoon Lan made landfall in Japan on Oct. 22, the Global Precipitation Measurement mission core satellite or GPM analyzed the storm and added up the high rainfall that it generated.

NASA’s REEL Science Communication Contest: High School Video and Animation Contest

NASA Earth Science missions are kicking off a new video contest engaging high school age students to produce a video communicating NASA Earth Science to younger students. Students are consuming over 10 hours of media a day and video is increasingly important to communicate and inform about science. NASA is looking for talented High School students to create videos that engage students in Earth Science.

Winners will have their videos posted on NASA’s website. They will also get the opportunity to be a NASA Producer working with NASA scientists and communication experts in July 2014 to produce an Earth Science feature video.

Flash Floods in Central Texas

A large storm system brought more than a foot of rain to parts of Central Texas on October 30 and 31, 2013. Up to 14 inches (36 cm) of rain fell in the Austin region, according to the National Weather Service. The rain triggered flash floods that left two people dead, forced evacuations, and closed roads. The clouds had largely cleared by 12:35 p.m. when the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite acquired the top natural color image. Normally black or dark blue, rivers and reservoirs are muddy brown and green from runoff. Read more

High Clouds Over South America

The view shown in this image is rare: a high bank of cirrus clouds sweeps east from the Andes Mountains of South America in otherwise clear skies. Under normal circumstances, other clouds would dominate the scene.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired the image on September 20, 2013, when strong upper level winds were blowing east across South America. Read more

Star Dunes in Algeria

In some areas, winds tend to blow in roughly the same general direction all year. The Grand Erg Oriental, a sprawling sea of sand dunes in the Saharan Desert, is not one of them.

The winds in northeastern Algeria tend to be complex and changing. Easterly summer winds shift in the winter, becoming westerly. Meanwhile, passing storms and local geographical features further muddle the picture. If winds came consistently from one direction, crescent-shaped barchan dunes would reign. But the dominant dune type along the southern edge of Grand Erg Oriental (shown above) are large, pyramid-shaped star dunes, which only form in areas where winds blow from multiple directions.

The image was acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite on October 27, 2012. Read more
