The GOES-16 Post-Launch Assessment Review (PLAR) was successfully completed on May 9. The PLAR is an evaluation of the readiness of the spacecraft systems to proceed with routine operations. An independent review team evaluated the flight and data operations readiness, satellite performance and the readiness to transfer responsibility from the development organization to the operations organization. The passage of this milestone keeps the program on track for the Handover Readiness Review in June.
The 2017 NOAA Satellite Conference (NSC) will be held July 17-20 at City College of New York. NSC 2017 will bring together users and providers of polar-orbiting and geostationary satellite data, data products, and applications from the public, private, and academic sectors. Representatives from more than 40 countries will participate in this event. The theme for the conference is “A New Era for NOAA Environmental Satellites.” Visit the conference website for more information and to take the pre-conference survey. Abstract submissions will be accepted until May 31, 2017.
The GOES-R Quarterly Newsletter for the time period January‒March 2017 is now available. The momentum continues with the release of the first data and imagery from GOES-16 and preparing the satellite to become operational in November. Scientists and engineers are hard at work to validate the entire system. View the 1Q 2017 newsletter, which highlights the first imagery from the satellite, post-launch activities, and preparations for launching GOES-S next year.
Flying out of Palmdale, California, NASA’s ER-2 high-altitude plane and its suite of highly specialized instruments took to the air over the Sonoran Desert in Mexico and the Mojave Desert in Ivanpah, California on March 23 and 28 to validate GOES-16’s ABI— the satellite’s primary instrument. Data from the ER-2 instruments were verified by an array of ground sensors and compared to ABI scans of the corresponding area. Learn more in this feature story.

When the topic du jour turns to satellite meteorology and its benefits, the spacecraft usually get all the attention. This stands to reason, but there is no denying that satellites are only half of the highly specialized technical apparatus that collects remotely sensed data and makes it available to scientists. The other, less talked-about half of this system is commonly referred to as the “ground system.” Learn more in this feature story.
It may seem that once a satellite is successfully launched, the work is done. But there’s a lot more that goes into making sure it’s ready to provide data for your local weather forecast. The GOES-16 satellite is currently undergoing post-launch testing. What does that mean? Launching a satellite is like opening a new restaurant. Post-launch testing is like a soft opening with a limited audience, which allows for trouble-shooting and preparing for the grand opening. During post-launch testing, there are periodic, planned data outages that are necessary to perform specific verification and validation functions. These outages are generally brief and part of normal post-launch testing, and they are part of the reason it’s important not to depend on GOES-16 data for operational needs during the testing period. Learn more about post-launch testing in this feature story.
The GOES-16 post-launch field campaign is now underway. During this three month campaign, a team of instrument scientists, meteorologists, GOES-16 engineers, and specialized pilots will use an outfit of high-altitude planes, ground-based sensors, unmanned aircraft systems (or drones), the International Space Station, and the NOAA/NASA Suomi NPP polar-orbiting satellite to collect measurements across the United States to support validation of the GOES-16 Advanced Baseline Imager and Geostationary Lightning Mapper instruments. Learn more about the field campaign in this feature story.
In recognition of the newly available GOES-16 cloud and moisture imagery, and providing an opportunity to reach out and expand user readiness, the GOES-R Series Program will offer a special one-day GOES-16 First Results workshop on April 27, 2017. The workshop will be held in conjunction with the 8th NOAA Testbeds and Proving Grounds Annual Workshop at the National Weather Service Training Center in Kansas City, Missouri. If you are interested in attending the GOES-16 First Results workshop, please complete the registration form.
NOAA's National Environmental Satellite, Data, and Information Service appreciates the enthusiasm in the weather community and support for our newest on-orbit satellite, GOES-16, which will enhance the weather forecasts that save lives and protect property nationwide.
At this time, data from GOES-16 are considered preliminary and are undergoing validation testing. NOAA is therefore requesting that any organizations that redistribute GOES-16 data -- before it is declared operational -- include the following disclaimer with the data:
"NOAA's GOES-16 satellite has not been declared operational and its data are preliminary and undergoing testing."
Users receiving these data through any dissemination means (including, but not limited to, PDA and GOES Rebroadcast) assume all risk related to their use of GOES-16 data and NOAA disclaims any and all warranties, whether express or implied, including (without limitation) any implied warranties of merchantability or fitness for a particular purpose.
It is expected that GOES 16 data will be declared operational, approximately 6-12 months after launch, which occurred in November 2016.
Space weather may sound like the stuff of science fiction, but it’s quite real and taken very seriously. Earth-bound radioactive waves and particles from a solar storm can disrupt communications, navigation, and power grids; cause damage to spacecraft; and even put astronauts and airline passengers at risk of exposure to space radiation.
Technologists have been aware of the threats posed by space weather for years and previous GOES satellites have carried space-weather instruments to monitor and predict potentially harmful space weather. However, none of these earlier instruments were as advanced or capable of providing as much information about the conditions of the sun and near-space environment as the space weather sensors aboard GOES-16. Learn why GOES-16 is our newest and best defense against the threats of space weather.
Detecting and predicting lightning just got a lot easier. The first images from the Geostationary Lightning Mapper (GLM), a new instrument onboard NOAA’s GOES-16 satellite, are giving forecasters richer information about lightning that will help them alert the public to dangerous weather.
This image shows 1.8 million lightning images accumulated by GLM over one hour, displayed over full disk imagery from the Advanced Baseline Imager. Brighter colors indicate more lightning energy was recorded; color bar units are the calculated kilowatt-hours of total optical emissions from lightning. The brightest storm system is located over the Gulf Coast of Texas.
The first images from the Solar Ultraviolet Imager (SUVI) instrument aboard the GOES-16 satellite captured a large coronal hole on the sun on January 29, 2017. The sun’s 11-year activity cycle is currently approaching solar minimum and during this time powerful solar flares become scarce and coronal holes become the primary space weather threat. Once operational, SUVI will capture full-disk solar images around-the-clock and will be able to see more of the environment around the sun than earlier NOAA geostationary satellites.
The new Space Environment In‐Situ Suite (SEISS) instrument onboard NOAA’s GOES-16 is working and successfully sending data back to Earth! This plot shows how fluxes of charged particles increased over a few minutes around the satellite on January 19, 2017. These particles are often associated with brilliant displays of aurora borealis at northern latitudes and australis at southern latitudes; however, they can pose a radiation hazard to astronauts and other satellites, and threaten radio communications. Information from SEISS will help NOAA's Space Weather Prediction Center provide early warning of these high flux events, so astronauts, satellite operators and others can take action to protect lives and equipment. This SEISS data shows injections of protons and electrons observed by the Magnetospheric Particle Sensors MPS-HI and Solar and Galactic Proton Sensor (SGPS) on January 19, 2017. MPS-HI and SGPS are two of the individual sensor units on SEISS. The fluxes shown are from the MPS-HI telescopes that look radially outward from the Earth, and from the lowest-energy channel observed by the eastward-looking SGPS.
SEISS is composed of five energetic particle sensor units. The SEISS sensors have been collecting data continuously since January 8, 2017, with an amplitude, energy and time resolution that is greater than earlier generations of NOAA’s geostationary satellites.
Solar flares are huge eruptions of energy on the sun and often produce clouds of plasma traveling more than a million miles an hour. When these clouds reach Earth they can cause radio communications blackouts, disruptions to electric power grids, errors in GPS navigation, and hazards to satellites and astronauts. The Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) instrument on NOAA’s GOES-16, built by the University of Colorado’s Laboratory for Atmospheric and Space Physics in Boulder, Colorado, measures solar flares at several wavelengths and improves upon current capabilities by capturing larger flares, measuring the location of the flares on the sun, and measuring flares in more wavelengths. The GOES-16 EXIS will provide forecasters at the NOAA’s Space Weather Prediction Center with early indications of impending space weather storms so they can issue alerts, watches and warnings.
The figure shows an example of EXIS observations at two different wavelengths of a flare that peaked at 11:05 UTC [6:05 a.m. EST] on January 21, 2017. This is a relatively small flare, yet the brightness of the sun in soft (lower energy) X-rays increased by a factor of 16. EXIS will give NOAA and space weather forecasters the first indication that a flare is occurring on the sun, as well as the strength of the flare, how long it lasts, the location of the flare on the sun, and the potential for impacts here at Earth.
NOAA’s GOES-16 satellite, formerly known as GOES-R, has sent its first, high-resolution images, and now people around the world can see what this revolutionary satellite sees. The first images usher in a new era of Earth and space weather observation for the U.S. View images and animations from GOES-16’s new Advanced Baseline Imager (ABI) instrument, showing the complete full disk of the Western Hemisphere and the continental United States in all 16 channels of the ABI instrument.

The GOES-R Quarterly Newsletter for the time period October-December 2016 is now available. The future of weather forecasting is here! After years of research, development and integration, GOES-R (now GOES-16) successfully launched on November 19, 2016, made it to geostationary orbit, and is sending back data! View the 4Q 2016 newsletter, which highlights the road to launch, launch and post-launch activities.
On December 22, 2016, the GOES-16 Magnetometer (MAG) became the first instrument on the satellite to begin transmitting data! Earth’s geomagnetic field acts as a shield, protecting us from hazardous incoming solar radiation. Geomagnetic storms, caused by eruptions on the surface of the sun, can interfere with communications and navigation systems, cause damage to satellites, cause health risks to astronauts, and threaten power utilities. When a solar flare occurs, GOES-16 will tell space weather forecasters where it happened on the sun and how strong it was. Using that information, forecasters can determine if the explosion of energy is coming toward Earth or not. The GOES-16 MAG samples five times faster than previous GOES magnetometers, which increases the range of space weather phenomena that can be measured. This plot shows preliminary data from the outboard Magnetometer instrument on board the GOES-16 satellite observed December 22, 2016.
