NASA - National Aeronautics and Space AdministrationPasadena, CA – New, detailed maps of the world’s natural landscapes created using NASA satellite data could help scientists better predict the impacts of future climate change.

The maps of forests, grasslands and other productive ecosystems provide the most complete picture yet of how carbon from the atmosphere is reused and recycled by Earth’s natural ecosystems.

Scientists at the University of Edinburgh, Scotland, United Kingdom; NASA’s Jet Propulsion Laboratory, Pasadena, California; and Wageningen University, Netherlands, used a computer model to analyze a decade of satellite and field study data from 2001 to 2010.

NASA’s Global Precipitation Measurement Satellite studies Thunderstorms in Southeastern United States

 

Written by Hal Pierce / Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Severe weather moved through the southern U.S. on February 2nd and 3rd, and NASA’s Global Precipitation Measurement or GPM core satellite examined the violent thunderstorms.

On February 3rd, 2016 at 1851 UTC (1:51pm ET/12:51pm CT) the GPM core observatory satellite flew over a line of storms extending from the Gulf coast of Florida through New York state. Tornadoes were spotted in Georgia and South Carolina within this area of violent weather.

On Feb. 3 at 1:51 p.m. EDT GPM found that one powerful thunderstorm in North Carolina was dropping rain at the extreme rate of 112.96 mm (4.4 inches) per hour. (NASA/JAXA/SSAI, Hal Pierce)

NASA uses Satellite data to create Damage Maps of Nepal’s Earthquake

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Nepal’s magnitude 7.8 Gorkha earthquake caused significant damage and loss of life in 2015. In natural disasters like this, it is critical to locate areas that are in the most need of assistance as fast as possible.

Quickly assessing and communicating where the hardest-hit areas are and prioritizing which regions or communities have the greatest need for first-response teams is difficult when a disaster unevenly devastates various parts of a large area. It helps to get a bigger-picture view of where the damage is located from a high vantage point: low-Earth orbit.

NASA studies the Oceans looking for answers to how fast they will rise in the future

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Seas around the world have risen an average of nearly 3 inches (8 centimeters) since 1992, with some locations rising more than 9 inches (25 centimeters) due to natural variation, according to the latest satellite measurements from NASA and its partners.

An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of several feet in the future.

The question scientists are grappling with is how quickly will seas rise?

NASA improves Storm Models and Forecasting since hurricane Katrina

 

Written by Kasha Patel
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – On August 28th, 2005, the National Hurricane Center issued a public notice warning people in New Orleans of “devastating damage expected…power outages will last for weeks…persons…pets…and livestock left exposed to the winds will be killed,” from the ensuing Hurricane Katrina.

The storm had formed near the Bahamas and south Florida before becoming a Category 2 hurricane over the Gulf region northwest of Key West. Then, in two days, the hurricane’s winds almost doubled to 175 mph, creating Category 5 Hurricane Katrina— the most intense hurricane in the past 36 years.

NASA’s Soil Moisture Active Passive (SMAP) satellite experiences instrument problem

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Mission managers at NASA’s Jet Propulsion Laboratory, Pasadena, California, are assessing an anomaly with the radar instrument on NASA’s Soil Moisture Active Passive (SMAP) satellite observatory.

The radar is one of two science instruments on SMAP used to map global soil moisture and detect whether soils are frozen or thawed.

On July 7th, at about 2:16pm PDT, SMAP’s radar halted its transmissions. All other components of the spacecraft continued to operate normally, including the radiometer instrument that is collecting science data.

NASA data used to help relief efforts in Nepal after Gorkha Earthquake

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA and its partners are gathering the best available science and information on the April 25th, 2015, magnitude 7.8 earthquake in Nepal, referred to as the Gorkha earthquake, to assist in relief and humanitarian operations.

Organizations using these NASA data products and analyses include the U.S. Geological Survey, United States Agency for International Development (USAID)/Office of U.S. Foreign Disaster Assistance, World Bank, American Red Cross, and the United Nations Children’s Fund.

NASA’s Soil Moisture Active Passive (SMAP) observatory completes test, produces First Global Maps

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – With its antenna now spinning at full speed, NASA’s new Soil Moisture Active Passive (SMAP) observatory has successfully re-tested its science instruments and generated its first global maps, a key step to beginning routine science operations next month.

SMAP launched January 31st on a minimum three-year mission to map global soil moisture and detect whether soils are frozen or thawed. The mission will help scientists understand the links among Earth’s water, energy and carbon cycles; help reduce uncertainties in predicting weather and climate; and enhance our ability to monitor and predict natural hazards such as floods and droughts.

NASA reports Researchers looking into United States Methane “Hot Spot”

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Researchers from several institutions are in the Four Corners region of the U.S. Southwest with a suite of airborne and ground-based instruments, aiming to uncover reasons for a mysterious methane “hot spot” detected from space.

“With all the ground-based and airborne resources that the different groups are bringing to the region, we have the unique chance to unequivocally solve the Four Corners mystery,” said Christian Frankenberg, a scientist at NASA’s Jet Propulsion Laboratory, Pasadena, California, who is heading NASA’s part of the effort.

NASA’s Soil Moisture Active Passive (SMAP) observatory completes spin-up procedure

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Mission controllers at NASA’s Jet Propulsion Laboratory in Pasadena, California, have commanded the 20-foot (6-meter) reflector antenna on NASA’s new Soil Moisture Active Passive (SMAP) observatory to begin spinning for the first time. The partial spin-up is a key step in commissioning the satellite in preparation for science operations.

Last week, mission controllers sent commands to release the locking mechanism that prevented the observatory’s spun instrument assembly — the part that spins — from rotating during launch and deployment of the reflector. The spun instrument assembly includes the spin control electronics, radiometer instrument and reflector antenna.
