The image shows the ATMS channel 18 data, which measures water vapor in the lower atmosphere. Tropical Storm Sean is visible in the data, as the patch of blue, in the Atlantic off the coast of the Southeastern United States. The data were processed at the NOAA Satellite Operations Facility (NSOF) in Suitland, Md.

The ATMS is one of five instruments on board the National Polar-orbiting Operational Environmental Satellite System Preparatory Project, or NPP, that launched from Vandenberg Air Force Base, Calif., on October 28. Since then, NPP has successfully completed all spacecraft commissioning activities and powered on all instruments. In the next few weeks, all instruments will be commissioned and NPP will be sending science data from the four remaining instruments by mid-December.
A passive microwave radiometer, the ATMS instrument can collect data even when it is cloudy. Paired with the Cross-track Infrared Sounder (CrIS), also aboard NPP, they will produce global sets of high-resolution temperature and moisture profiles that are used for forecasting and studying weather.
"NPP is rock solid," stated Ken Schwer, NPP project manager at NASA's Goddard Space Flight Center, Greenbelt, Md. "The satellite has performed extremely well during the checkout maneuvers and is in the expert hands of the mission operations team at NSOF."
During the commissioning activities, which were completed November 5, the NPP spacecraft subsystems were successfully tested, including command and control, propulsion and communications. NPP spacecraft and instrument data is sent from the spacecraft to the ground station in Svalbard, Norway and then to the NSOF.
In addition to the ATMS and the CrIS instruments, NPP carries 3 more state-of-the-art sensors that will provide critical information concerning long-term climate patterns and will help meteorologists improve short-term weather forecasts. During the satellite's five-year life, the mission will extend more than 30 key long-term datasets NASA has been tracking, including measurements of the ozone layer, and land and ice cover.
"NPP data will improve our forecast skills out to 5 to 7 days in advance of extreme weather events, including hurricanes, and severe weather outbreaks," said Dr. Louis Uccellini, director of NOAA's National Centers for Environmental Prediction. "With NPP, our goal is to make the accurate forecasts achieved for this year's events even better in the future."
NPP serves as a bridge mission between NASA's Earth Observing System (EOS) of satellites and the next-generation Joint Polar Satellite System, a National Oceanic and Atmospheric Administration (NOAA) program that will also collect weather and climate data.
The NPP mission is managed by NASA's Goddard Space Flight Center in Greenbelt, Md., for the Earth Science Division of the Science Mission Directorate at NASA Headquarters in Washington. The Joint Polar Satellite System program provides the NPP ground system. NOAA will provide operational support for the mission.For more information about NPP, visit:

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
