Turns out if you want to find out where the water is on Earth, gravity can help. Specifically, if you want to find out where water is below the Earth’s surface, satellites can use the force of gravity to figure that out… from space. Which is SO COOL.
If you don’t know what you want to be when you grow up, be a scientist. this stuff is so cool.
-Rachel Maddow introducing new studies about NASA research about water aquifers.
Jay Famiglietti, senior water scientist at the NASA Jet Propulsion Laboratory, talks with Rachel Maddow about new research using satellites to detect underground water around the world and finding startling deficiencies in the global water supply.
NASA has launched SMAP, a new satellite to study water, not in oceans or lakes but in the soil beneath our feet. This often overlooked repository of water can have big effects on weather, climate, drought and agriculture.
National Weather Service forecasters have been tracking a low pressure area that moved from the Midwest into the Atlantic Ocean today, and is expected to become a strong nor’easter that will bring blizzard conditions to the northeastern U.S. The path of the system was captured in a NASA movie of NOAA’s GOES-East satellite imagery.
A huge swirling storm ravaged the northeast Pacific earlier this week. Here is a sweet GIF of satellite image showing the swirling storm’s birth in the Pacific! From youtube video of Tom Yulsman.
As a massive and powerful cyclone with winds exceeding hurricane strength (http://www.washingtonpost.com/blogs/c…) swirled in the northeast Pacific, the GOES-15 weather satellite captured the images that comprise this animation. The imagery come from the satellite’s 6.5 µm water vapor channel imagery. It shows the development and evolution of the storm between Sept. 21 and 23, 2014.
You may have seen my previous post last week showing satellite imaging of tropical storm Arthur. This week NASA has released a video of similar satellite imaging of Typhoon Neoguri, which is considerably more impressive. I made the gif above from this youtube video. Last week’s post on tropical storm Arthur is here, and the gif from that post is below also for comparison of the two storms.
NASA’s TRMM Satellite Sees Heavy Rainfall in Typhoon Neoguri On July 7 at 2:41 a.m. EDT the TRMM satellite had a near perfect view as it passed above the center of Typhoon Neoguri. Heaviest rainfall was occurring at over 106 mm (4.2) inches per hour in feeder bands southeast of Neoguri’s eye. Image Credit: NASA/SSAI, Hal Pierce
