NASA SMAP Creates Surface Flooding Maps from Hurricane Harvey
and has no comments yet.
A new series of images generated with data from NASA's Soil Moisture Active Passive (SMAP) satellite illustrate the surface flooding caused by Hurricane Harvey from before its initial landfall through August 27, 2017. Harvey is now a depression spreading heavy rainfall through the south central and southeastern U.S.The SMAP observations detect the proportion of the ground covered by surface water within the satellite's field of view. The sequence of images depicts successive satellite orbital swath observations showing the surface water conditions on August 22, before Harvey's landfall and then on Aug. 27, two days after landfall.

NASA Eyes Pineapple Express Soaking California
and has no comments yet.
NASA has estimated rainfall from the Pineapple Express over the coastal regions southwestern Oregon and northern California from the series of storms in February, 2017.The West Coast is once again feeling the effects of the "Pineapple Express." Back in early January one of these "atmospheric river" events, which taps into tropical moisture from as far away as the Hawaiian Islands, brought heavy rains from Washington state and Oregon all the way down to southern California. This second time around, many of those same areas were hit again. The current rains are a result of three separate surges of moisture impacting the West Coast. The first such surge in this current event began impacting the Pacific coastal regions of Washington, Oregon, and northern California on February 15.

NASA Examines Ex-Tropical Cyclone Dineo's Rainfall
and has no comments yet.
Late on Feb. 15, Dineo made landfall in southern Mozambique. By Feb. 17 the storm weakened to a remnant low pressure area when NASA's Terra satellite passed overhead. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Terra captured a visible image that showed the center of the low pressure area over Zimbabwe and clouds extended over found Dineo's clouds stretched over southern Mozambique, Swaziland, eastern Botswana and northeastern South Africa.

Snow Science in Support of Our Nation's Water Supply
and has no comments yet.
Researchers have completed the first flights of a NASA-led field campaign that is targeting one of the biggest gaps in scientists' understanding of Earth's water resources: snow.NASA uses the vantage point of space to study all aspects of Earth as an interconnected system. But there remain significant obstacles to measuring accurately how much water is stored across the planet's snow-covered regions. The amount of water in snow plays a major role in water availability for drinking water, agriculture and hydropower.

Descent into a Frozen Underworld
and has no comments yet.
Mt. Erebus is at the end of our world -- and offers a portal to another.It's our planet's southernmost active volcano, reaching 12,448 feet (3,794 meters) above Ross Island in Antarctica. Temperatures at the surface are well below freezing most of the year, but that doesn't stop visits from scientists: Erebus is also one of the few volcanoes in the world with an exposed lava lake. You can peer over the lip of its main crater and stare straight into it.
