NASA's GPM observes Arkansas and Tennessee flooding downpours

02.03.2018

The Global Precipitation Measurement mission or GPM core satellite provided forecasters with a look at the rainfall rates in storms drenching Arkansas and Tennessee.

NOAA's National Weather Service has issued flood advisories and flood warnings for large areas of Arkansas and Tennessee on March 1. Large parts of the Ohio Valley and Mississippi valley have received flooding rainfall during the past week. Arkansas has seen more rain than any other state.


On Feb. 28, 2018 at 11:15 p.m. CST, GPM data was used to create 3-D views that showed intense storms extending from Oklahoma into southwestern Arkansas. Storm tops in the area were shown by GPM to reach heights above 5.6 miles (9 km).

Life threatening flood conditions have resulted from over 10 inches (254 mm) of rain falling in extensive areas of central Arkansas.

The GPM core observatory satellite had an excellent view of the storms that were producing flooding rainfall in Arkansas when it flew above the state on Wednesday February 28, 2018 at 11:15 p.m. CST (March 1 at 0515 UTC). A rainfall analysis was derived from data received by the satellite with GPM's microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) instruments.

GPM's radar passed directly above storms that were dropping heavy rain over southwestern Arkansas. GPM's radar (DPR) indicated that some of these storms were dropping rain at greater than 5.1 inches (30.7 mm) per hour. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.

At NASA's Goddard Space Flight Center in Greenbelt, Md. the GPM satellite's 3-D radar data (DPR Ku Band) were used to show the vertical structure of precipitation falling over Arkansas. These 3-D views use GPM's radar data to reveal simulated cross-sections of intense storms that were extending from Oklahoma into southwestern Arkansas. Storm tops in the area were shown by GPM to reach heights above 5.6 miles (9 km).

On March 1, the National Weather Service in Little Rock, Arkansas noted "Much of central and southern Arkansas has seen between one and three inches, with isolated higher amounts, of rainfall over the last 24 hours. This has only aggravated the flooding situation across the area. Excessive runoff will continue today, even well after the rain ends."

Im Focus: Small particles, big effects: How graphene nanoparticles improve the resolution of microscopes

Conventional light microscopes cannot distinguish structures when they are separated by a distance smaller than, roughly, the wavelength of light. Superresolution microscopy, developed since the 1980s, lifts this limitation, using fluorescent moieties. Scientists at the Max Planck Institute for Polymer Research have now discovered that graphene nano-molecules can be used to improve this microscopy technique. These graphene nano-molecules offer a number of substantial advantages over the materials previously used, making superresolution microscopy even more versatile.

Microscopy is an important investigation method, in physics, biology, medicine, and many other sciences. However, it has one disadvantage: its resolution is...

Im Focus: Atoms don't like jumping rope

Nanooptical traps are a promising building block for quantum technologies. Austrian and German scientists have now removed an important obstacle to their practical use. They were able to show that a special form of mechanical vibration heats trapped particles in a very short time and knocks them out of the trap.

By controlling individual atoms, quantum properties can be investigated and made usable for technological applications. For about ten years, physicists have...

An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.

With new images from NJIT's Big Bear Solar Observatory (BBSO), the researchers have revealed in groundbreaking, granular detail what appears to be a likely...
