NASA works with NOAA to better detect Monsoon Flash Floods using GPS Sensors

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – In the American Southwest and in northwestern Mexico, more than half the annual rainfall often comes in the form of the torrential and unpredictable downpours of the North American monsoon. As in monsoon seasons across the tropics, a summertime reversal of winds carries streams of moisture from over the oceans or, in this case, the Gulf of California and Gulf of Mexico, and unceremoniously dumps them on the sunbaked land.

Perhaps the least understood and most erratic weather pattern in the United States, the monsoon brings precipitation that is vital to agriculture and the ecosystem, but it also presents serious threats to life, limb, and property.

North American monsoons can be unpredictable, erratic and bring severe flash flooding to dry, sunbaked areas. (National Oceanic and Atmospheric Administration)

NASA launches NOAA Weather Satellite into orbit

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA successfully launched the second in a series of next-generation weather satellites for the National Oceanic and Atmospheric Administration (NOAA) at 6:02pm CST Thursday.

NOAA’s Geostationary Operational Environmental Satellite-S (GOES-S) lifted off on a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

GOES-S mission managers confirmed at 7:58pm the spacecraft’s solar arrays successfully deployed and the spacecraft was operating on its own power.

NASA ends Tropospheric Emission Spectrometer instrument’s mission

NASA - National Aeronautics and Space AdministrationWashington, D.C. – On January 31st, NASA ended the Tropospheric Emission Spectrometer’s (TES) almost 14-year career of discovery. Launched in 2004 on NASA’s Aura spacecraft, TES was the first instrument designed to monitor ozone in the lowest layers of the atmosphere directly from space. Its high-resolution observations led to new measurements of atmospheric gases that have altered our understanding of the Earth system.

TES was planned for a five-year mission but far outlasted that term.

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA engineer Manuel Vega can see one of the Olympic ski jump towers from the rooftop of the South Korean weather office where he is stationed. Vega is not watching skiers take flight, preparing for the 2018 PyeongChang Winter Olympics and Paralympic games.

Instead, he’s inspecting the SUV-sized radar beside him. The instrument is one of 11 NASA instruments specially transported to the Olympics to measure the quantity and type of snow falling on the slopes, tracks and halfpipes.

NASA’s TSIS-1 instrument to monitor Earth’s Ozone Layer

 

Written by Rani Gran
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – High in the atmosphere, above weather systems, is a layer of ozone gas. Ozone is Earth’s natural sunscreen, absorbing the Sun’s most harmful ultraviolet radiation and protecting living things below. But ozone is vulnerable to certain gases made by humans that reach the upper atmosphere. Once there, they react in the presence of sunlight to destroy ozone molecules.

Currently, several NASA and National Oceanic and Atmospheric Administration (NOAA) satellites track the amount of ozone in the upper atmosphere and the solar energy that drives the photochemistry that creates and destroys ozone.

TSIS-1 will be affixed to the International Space Station in December 2017 TSIS-1 operates like a sun flower: it follows the Sun, from the ISS sunrise to its sunset, which happens every 90 minutes. At sunset, it rewinds, recalibrates and waits for the next sunset. (NASA/LASP)

NASA launched NOAA’s Joint Polar Satellite System-1 into orbit Saturday

 

Written by Steve Cole
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA has successfully launched for the National Oceanic and Atmospheric Administration (NOAA) the first in a series of four highly advanced polar-orbiting satellites, equipped with next-generation technology and designed to improve the accuracy of U.S. weather forecasts out to seven days.

The Joint Polar Satellite System-1 (JPSS-1) lifted off on a United Launch Alliance Delta II rocket from Vandenberg Air Force Base, California, at 1:47am PST Saturday.

At Vandenberg Air Force Base's Space Launch Complex 2, the Delta II rocket engines roar to life. The 1:47am PST (4:47am EST), liftoff begins the Joint Polar Satellite System-1, or JPSS-1, mission. JPSS is the first in a series four next-generation environmental satellites in a collaborative program between NOAA and NASA. (NASA)

NASA’s studying of Earth will help to discover Life on another Planet

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As a young scientist, Tony del Genio of NASA’s Goddard Institute for Space Studies in New York City met Clyde Tombaugh, the discoverer of Pluto.

“I thought, ‘Wow, this is a one-time opportunity,'” del Genio said. “I’ll never meet anyone else who found a planet.”

That prediction was spectacularly wrong. In 1992, two scientists discovered the first planet around another star, or exoplanet, and since then more people have found planets than throughout all of Earth’s preceding history.

NASA’s CERES Flight Model 6 instrument to help study Earth’s Energy Budget

 

Written by Eric Gillard
NASA Langley Research Center

NASA - National Aeronautics and Space AdministrationHampton, VA – The Earth and its interconnected systems have always been a fascination for Norman Loeb.

“It’s quite an interesting thing when you think about how energy is distributed and exchanged in various forms amongst Earth’s atmosphere, ocean, land and snow surfaces,” he said.

As the principal investigator of NASA’s Radiaton Budget Science Project, Loeb oversees a series of space-borne instruments that measure reflected sunlight and thermal radiation emitted by the Earth. It gives him a chance to satisfy his curiosity about our home planet from NASA’s Langley Research Center in Hampton, Virginia.

Earth’s energy budget describes the balance between the radiant energy that reaches Earth from the sun and the energy that flows from Earth back out to space. (NASA)

NASA’s Orbiting Carbon Observatory-2 (OCO-2) satellite data reveals reasons for Earth’s Carbon Dioxide Rise

 

Written by Dwayne Brown
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A new NASA study provides space-based evidence that Earth’s tropical regions were the cause of the largest annual increases in atmospheric carbon dioxide concentration seen in at least 2,000 years.

Scientists suspected the 2015-16 El Nino — one of the largest on record — was responsible, but exactly how has been a subject of ongoing research. Analyzing the first 28 months of data from NASA’s Orbiting Carbon Observatory-2 (OCO-2) satellite, researchers conclude impacts of El Nino-related heat and drought occurring in tropical regions of South America, Africa and Indonesia were responsible for the record spike in global carbon dioxide.

The last El Nino in 2015-16 impacted the amount of carbon dioxide that Earth's tropical regions released into the atmosphere, leading to Earth's recent record spike in atmospheric carbon dioxide. The effects of the El Nino were different in each region. (NASA-JPL/Caltech)

NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA-NOAA’s Suomi NPP Satellite provided a night-time and infrared look at the Atlantic’s latest hurricane that revealed the power under the clouds. NASA’s GPM also provided a look at the rainfall being generated by Hurricane Irma.

After forming in the eastern Atlantic Ocean on Wednesday tropical storm Irma strengthened and became a powerful category three hurricane on Thursday August 31st, 2017.

On Sept. 1st at 0347 UTC (Aug. 31 at 11:47 p.m. EDT) the VIIRS instrument aboard NASA-NOAA’s Suomi NPP satellite captured a night-time image of Hurricane Irma in the Atlantic Ocean that showed a tight circulation. (NASA/NOAA/UWM-CIMSS, William Straka III)
