The GOES-R series, NOAA's next-generation geostationary weather satellites, is a game changer. These satellites, beginning with the launch of GOES-R, will provide continuous imagery and atmospheric measurements of Earth’s Western Hemisphere, total lightning data, and space weather monitoring to provide critical atmospheric, hydrologic, oceanic, climatic, solar and space data.
These measurements will lead to significant improvements in the detection and observations of meteorological phenomena that directly affect public safety, protection of property and our GOES fleet in the GOES-R era nation’s economic health and prosperity.

An Atlas V rocket was all set 2 days ago to launch from Cape Canaveral, Florida, sending a NASA-built weather satellite into orbit.
It’s the GOES-R probe, and it’s being touted as a game changer for weather forecasting.
The spacecraft, which will also be operated by the National Oceanic and Atmospheric Administration, is supposed to provide incredible real-time images of developing storm systems, better than any satellite that has preceded it.
GOES-R will keep an eye on Earth’s weather as it orbits 22,000 miles above.
But how does your local weather forecaster know what GOES-R sees?
Learn how GOES-R’s data is used for your local weather forecast in this animated video.
GOES-R even has a lightning mapper on board
To
do this, GOES-R — which stands for Geostationary Operational
Environmental Satellite-R — will scan Earth’s skies five times faster
than the other GOES satellites currently in orbit, with four times the
spatial resolution.
“This means we’ll have better quality data at high
resolution far more often than we do today,” Joe Pica, director of the
Office of Observations at NOAA, said at a NASA press conference.
Such information will allow NOAA scientists to see developing weather
systems in unprecedented detail, which will improve our tracking of
tornadoes, hurricanes, and wildfires.
GOES-R even has a lightning mapper
on board, meant to help forecasters know which storms are more severe
than others.
The information the satellite receives will help refine
seasonal and weather predictions, improve warning times before storms,
as well as help plan the best flight routes for airplanes.
While GOES-R will tell us more about the climate of
Earth, the satellite is also equipped to give us more information about
what our Sun is up to as well.
Specifically, the probe will be able to measure the intensity of solar flares,
which are responsible for causing “space weather” around Earth.
A flare
is often accompanied by something called a coronal mass ejection (CME) —
a huge burst of charged particles that shoots out from the Sun.
These
CMEs can clash with our planet’s magnetic field, causing geomagnetic
storms that mess with our satellites, communications systems, and even
our power grid. GOES-R will be able to tell scientists whether a
potentially problematic geomagnetic storm is headed our way.
In order to get all of this high quality weather
information, GOES-R is headed to a geostationary orbit — a circular path
about 22,000 miles above the Earth’s equator.
This is a preferred orbit
for many communication satellites, because spacecraft moving along this
path follow the rotation of the planet.
That way, they appear to be in
the same spot in the sky at all times.
Once it gets to geostationary
orbit, GOES-R will be renamed GOES-16 and begin its science operations
in about a year.
