    NEW AGE IN WEATHER FORECASTING BEGINS WITH SPECTACULAR 1ST IMAGES FROM NASA/NOAA GOES-16 OBSERVATORY

    KENNEDY SPACE CENTER, FL – A new age has begun in the nations weather forecasting capabilities with the release today (Jan. 23) of the spectacular first images gathered by the recently launched NASA/NOAA GOES-16 observatory.
    The highly advanced Geostationary Operational Environmental Satellite-16 (GOES-16) weather observatory lifted off two months ago atop a ULA Atlas V rocket on Nov. 19, 2016 from Space Launch Complex 41 (SLC-41) on Cape Canaveral Air Force Station, Florida.
    GOES-16 (formerly known as GOES-R through the launch) is the first in a new series of revolutionary NASA/NOAA geostationary weather satellites that entails the first significant instrument upgrade to US weather forecasting capabilities in more than two decades.
    “It will be like high-definition from the heavens,” says NOAA.
    “Today’s release of the first images from #GOES16 signals the start of a new age in satellite weather observation!!!”
    Thus the newly obtained and published imagery has been anxiously awaited by scientists, meteorologists and ordinary weather enthusiasts.
    “This is such an exciting day for NOAA! One of our GOES-16 scientists compared this to seeing a newborn baby’s first pictures — it’s that exciting for us,” said Stephen Volz Ph.D. director of NOAA’s Satellite and Information Service, in a statement.
    “These images come from the most sophisticated technology ever flown in space to predict severe weather on Earth. The fantastically rich images provide us with our first glimpse of the impact GOES-16 will have on developing life-saving forecasts.”

    This image clearly shows the significant storm system that crossed North America that caused freezing and ice that resulted in dangerous conditions across the United States on January 15, 2017 resulting in loss of life. Credit: NOAA/NASA
    An especially eye-popping image taken by GOES -16 from its equatorial vantage point situated in geostationary orbit 22,300 miles (35,800 kilometers) above Earth and published today, shows both the Earth and the Moon together – as the lead image here.
    The Earth/Moon combo shot is not only fantastically pleasing to the eye, but also serves a significant scientific purpose.
    “Like earlier GOES satellites, GOES-16 will use the moon for calibration,” say NOAA officials.
    “GOES-16 will boost the nation’s weather observation network and NOAA’s prediction capabilities, leading to more accurate and timely forecasts, watches and warnings.”
    GOES-16 is the most advanced and powerful weather observatory ever built and will bring about a ‘quantum leap’ in weather forecasting.
    “Seeing these first images from GOES-16 is a foundational moment for the team of scientists and engineers who worked to bring the satellite to launch and are now poised to explore new weather forecasting possibilities with this data and imagery,” said Volz.
    “The incredibly sharp images are everything we hoped for based on our tests before launch. We look forward to exploiting these new images, along with our partners in the meteorology community, to make the most of this fantastic new satellite.”
    It’s dramatic new imagery will show the weather in real time enabling critical life and property forecasting, help pinpoint evacuation zones and also save people’s lives in impacted areas of severe weather including hurricanes and tornadoes.
    And the huge satellite can’t come online soon enough, as demonstrated by the severe winter weather and tornadoes that just wreaked havoc and death in various regions of the US.
    Another breathtaking image product (seen below) produced by the GOES-16 Advanced Baseline Imager (ABI) instrument, built by Harris Corporation, shows a full-disc view of the Western Hemisphere in high detail — at four times the image resolution of existing GOES spacecraft.

    This composite color full-disk visible image shows North and South America and was taken on January 15, 2017. It was created using several of the 16 spectral channels available on the GOES-16 Advanced Baseline Imager (ABI) instrument. Credit: NOAA/NASA
    The 11,000 pound satellite was built by prime contractor Lockheed Martin and is the first of a quartet of four identical satellites – comprising GOES-R, S, T, and U – at an overall cost of about $11 Billion. This will keep the GOES satellite system operational through 2036.
    This next generation of GOES satellites will replace the currently operating GOES East and GOES West satellites.
    NOAA will soon decide whether GOES-16 will replace either the East or West satellites. A decision from NOAA is expected in May. GOES-16 will be operational by November 2017 as either the GOES-East or GOES-West satellite. Of course everyone wants it first.
    The six instrument science suite includes the Advanced Baseline Imager (ABI). ABI is the primary instrument and will collect 3 times more spectral data with 4 times greater resolution and scans 5 times faster than ever before – via the primary Advanced Baseline Imager (ABI) instrument – compared to the current GOES satellites.
    “The higher resolution will allow forecasters to pinpoint the location of severe weather with greater accuracy. GOES-16 can provide a full image of Earth every 15 minutes and one of the continental U.S. every five minutes, and scans the Earth at five times the speed of NOAA’s current GOES imagers.”

    The Curious Incident of Snow in The Netherlands


    It was as though a spotlight had illuminated them: a few dozen fields in Heensche Molen glowed white. Yet the snow that left a distinct patch on this hamlet in The Netherlands also left neighboring areas untouched, with the landscape cloaked in the muted browns and greens of winter.
    Snow fell that January 2017 day in northwestern Europe, but not everywhere. The Netherlands and Belgium were dusted in a freckle-pattern, with white powder covering some fields, while others remained completely bare. The Operational Land Imager (OLI) on Landsat 8 captured a view of this anomaly on January 19, 2017, a couple of days after the snowfall. Those white freckles were signs of a rare and somewhat obscure phenomenon.
    Fog-induced snow (not a formal scientific term) typically forms next to industrial sites. Big chimneys release water vapor and other gases and particulates, which can lead to the formation of fog. It also turns out that these emissions can create snow when the weather gets cold enough.

    acquired January 19, 2017download large image (6 MB, JPEG, 2084x2489)


    In December 2007, a cold fog over The Netherlands started to develop into a thick stratus cloud. Wim van den Berg, a researcher for MeteoGroup Netherlands, described the event in a 2007 paper: “Mixing within the fog caused the temperature to drop gradually to -4 or -5 degrees Celsius (25 Fahrenheit) throughout the cloud. The temperature decrease caused additional condensation into tiny water droplets but also ice crystals. In such a mixed cloud the Wegener-Bergeron process starts, and ice nuclei grow at the expense of water droplets with small snowflakes as a result...Locally, really large snowflakes were observed and a snow depth resulted of 3–5 centimeters (1.2–2 inches).”
    That is likely what happened in January 2017, van den Berg believes. “After many days with fog and/or low clouds and subfreezing temperatures, on January 17 several places reported snow,” he wrote in an email. “It was very local, mostly west of industry,” as surface wind was light easterly, “but it did cause some unexpected slipperiness.”
