Farewell, GOES-12…

| August 19, 2013 @ 11:51 am

Farewell to a valuable set of eyes 22,300 miles above us!

This is what GOES-12 looked like as crews with Space Systems/Loral prepared for its July 23, 2001 launch into space...

This is what GOES-12 looked like as crews with Space Systems/Loral prepared for its July 23, 2001 launch into space…

GOES-12, the weather satellite launched in July, 2001 by the National Oceanic and Atmospheric Administration, is being retired, its operators have announced.

Intended to operate for about five years, GOES-12 turned out to be a warrior, instead, wildly surpassing expectations.

Going into service April 1, 2003, the satellite sat above the Equator, monitoring developing weather systems across the eastern United States and part of the Atlantic ocean for about ten years.

Under its watch, the satellite—which became known as GOES-East—saw a lot, including Hurricane Katrina’s devastating strike along the Gulf coast in 2005, the Christmas blizzard that pounded the central U.S. in 2009, and countless severe weather episodes.

There’s no telling how many lives have been saved with the help of this marvel of technology.

GOES-12 even did a bit of traveling, itself. In May, 2010, the satellite was shifted south of the Equator and provided coverage over South America, where it monitored wildfires, drought and volcanic ash clouds.

In the place of GOES-12 is GOES-13, serving as the current GOES-East, which works in partnership with GOES-15. Together, these two satellites provide coverage from the Atlantic ocean west across the entire continental U.S., into the Pacific ocean.

If you’re curious about the break in numbers (what happened to GOES-14?), there’s an explanation.

GOES-14 is up there, too, but is not in service. Instead, it remains available as a stand-by/back-up, should a problem develop with either GOES-13 or GOES-15.

GOES, by the way, stands for Geostationary Operational Environmental Satellite.

What’s next for GOES-12?

NOAA will use up the satellite’s remaining fuel to boost it to a higher orbit (so it will be less of a collision threat to operational spacecraft), its batteries will be disabled, and transmitters will be turned off (to reduce any potentially interfering signals).

Just how much did GOES-12 see during its service time? NOAA has taken ten years worth of GOES-12 observations and packed them into 3 minutes:

Helena Market Days

A Severe Weather Voice Goes Silent

| December 12, 2012 @ 11:52 am

No one knows for sure how many tornado or severe thunderstorm watches and warnings he monitored, or how many hours he stayed at his post, but—in the 30-something years of being available around the clock to deal with Alabama weather—one thing is for sure.

Birmingham resident Carl Grover was a machine, relentless in his dedication to helping make sure that area residents received advance warning of approaching severe weather.

Grover, who was an amateur radio operator, spent decades volunteering as the primary liaison between central Alabama ham radio operators and the National Weather Service’s Birmingham Forecast Office.

When hams observed tornadoes, flooding, hail or other severe weather, they would tune in the Birmingham Amateur Radio Club’s 146.880 MHz repeater (a wide area coverage two-way radio system), looking for Carl. And, day or night, 2 a.m. or 2 p.m., nights, weekdays, weekends or holidays, they would find KA4JIR (Carl’s amateur radio call sign) monitoring the radio channel, waiting to take their information.

Carl would immediately call the Forecast Office and advise meteorologists, keeping them current on what storm spotters were seeing in the field.

In an era before Doppler weather radar, cell phones, camera-equipped smart phones, texting or instant messaging, the information Carl helped relay was frequently a consideration in whether the NWS issued a warning.

Sometimes, the forecasters would call Carl, asking him to find out what radio amateurs in a particular area were seeing, as part of the effort to obtain “ground truth” by verifying what radar might be indicating.

Is there actually a tornado on the ground? There were times that this was the only way forecasters could know for sure.

There is no way to know how many severe weather warnings may have been issued to protect the public, as a result of the cooperative effort Carl so frequently helped lead. Today, the work continues, but with a new generation at the controls.

Considered by many to be the father of amateur radio Skywarn communications in Birmingham, Carl passed away Sunday, December 9th. He was 86.

When severe storms threatened, it was always Carl’s voice on local amateur radio frequencies, providing operators with updates on current watches and warnings.

When it came to maintaining on-air decorum, it was Carl who gave unsuspecting radio amateurs the necessary corrections, reminding them that only important weather-related communications were appropriate. Those who deviated typically only did so once.

Carl was also a regular reporter of rain totals from his home near Eastwood Mall.

During the 1980s, as technology advanced and the Skywarn program’s value became more recognized for its life-saving potential, amateur radio operators and clubs began creating more formalized protocols on how to provide severe weather communications support more effectively.

It was also during this time that Carl and his late wife, Patsy, who also had an amateur radio license, organized Skywarn spotter classes in conjunction with the NWS. The classes took place at WVTM-TV atop Red Mountain (when James Spann was chief meteorologist and I anchored weather on the weekends) and drew radio amateurs from throughout central Alabama.

This was a valuable opportunity for training, with meteorologist Jay Shelley explaining what the Weather Service’s WSR-57 radar, based in Brent, could, and could not, see.

When the Weather Service went through a modernization in the late 1980s and 1990s, the changes affected how amateur radio operators throughout the Birmingham area would assist forecasters. To better serve the agency, Birmingham area hams formed ALERT, an organization dedicated to providing emergency communications support to the NWS upon its relocation from Birmingham to Calera as part of the modernization program.

With the shift to ALERT’s more formal operating system for handling severe weather communications, the stage could have been set for a clash between Grover’s long-held operating style and the new organization stepping in with its own rules and procedures.

Instead, Grover acted as a team player.

Operating a business out of his home helped give Carl the ability to get on the air and relay information quickly when severe weather threatened. His voice was often the first to be heard on local amateur radio frequencies when tornado, severe thunderstorm, flash flood and other watches were issued for the Birmingham area.

Once responding hams were able to get on site at the NWS to provide requested communications support, Carl would step aside and let ALERT’s operators take over. The result was a smooth and professionally run network that benefitted not just radio amateurs, but the Weather Service, other agencies and the public.

Carl is survived by three daughters and seven grand children.

“He was very dedicated,” said Ron Arant, a Shelby Co. amateur radio operator who remembers Carl providing severe weather communications during the mid 1980s. “He was somebody who had the public interest at heart.”

NWA 2011: A Volunteer’s Perspective

| October 20, 2011 @ 5:22 pm | 14 Replies

Trying to select a highlight from this week’s annual meeting of the National Weather Association is sort of like walking into your favorite bakery or doughnut shop and having to pick the treat you want most. Good luck. Pink or chocolate icing? With or without sprinkles? The task may be easier said than done.

There were so many informative presentations and panel discussions. There were so many prominent people from the meteorological, scientific, commercial and broadcast industries, and government, gathering at one spot, unleashing and sharing an incredible amount of knowledge.

Hydrology Lesson with Roger McNeil

Roger McNeil, a meteorologist with the National Weather Service, gives Alabama teachers a lesson in hydrology.

Long before the first speaker ever stepped to the podium, the momentum of this week had been building. WeatherFest, the October 15th gathering of weather experts and the public at McWane Science Center in downtown Birmingham, was one of the catalysts for the success of this week.

WeatherFest’s weather was perfect, the turnout huge, and the enthusiasm tremendous. I saw the excitement in the eyes of young children, many of whom were probably getting a rare chance to be exposed to the sciences. We desperately need more young people pursuing careers in the sciences. Perhaps WeatherFest’s opportunities for such close up, hands-on involvement may have ignited the fire in some of these young minds. Our answer will come years from now.

Dry Ice fun

H. Michael Mogil, a meteorologist and author, shares some fun weather demonstrations with teachers at NWA 2011 in Birmingham

As the NWA meeting itself got underway, it became obvious that the planning and logistical organizational work that started long ago had paid off.

From the next generation of weather satellites to dual polarization radar, from hurricanes to EF5 tornadoes, from ice to severe weather forecasting and research, a diverse array of experts shared thoughts and experiences, discussing what we’ve learned, and—very important—what we still need to learn.

What we still need to learn received heavy emphasis at the meeting because of Alabama’s April 27th severe weather outbreak. With all our sophisticated technology and so much advance notice, experts and non-experts alike ask why so many people had to die that day. It’s not an easy question to answer. But Tuesday’s Town Hall meeting took a serious try at finding answers that may well keep future generations alive.

As a volunteer, NWA was a wonderful experience (I played an extremely small role, about the size of one sprinkle on one of those doughnuts!). Being around so many experts and getting to sit in during this incredible sharing of knowledge was a rare opportunity and one I enjoyed tremendously. It was very educational … and loads of fun.

All of us who were involved in NWA 2011 have our memorable moments from the week of gatherings.

I’ll always treasure getting to help with Sunday’s session of meteorology students, who got tips and mentoring from some of our nation’s most prominent people in science, aerospace, government and broadcasting on how to get a successful career underway.

Getting started in a weather career

Meteorology students attending NWA 2011 in Birmingham get advice on how best to get their careers started.

Looking across these students, I realized that the torch is being handed off, right in front of our eyes.

We are watching the next generation of scientists, researchers, forecasters and broadcasters move through a critical chapter in their lives. One of these young men or women may be who makes a startling breakthrough in atmospheric research, teaching us something new about our planet, or who develops a new way of understanding storm structure and behavior. Future mothers, fathers and children may owe their very survival to what these young people wind up accomplishing. And yes, the next James Spann is probably in this group, too (but I didn’t see anyone who had lost their hair—at least not yet!).

Another memory that’s hard to lose is seeing James almost break into tears, as he talks with a group of teachers about the horror of April 27th. It is still too raw to talk about. Too personal.

NWA 2011 was a lot more than just a meeting of weather experts. It was a chance for Birmingham to show its best to people from all across the country and the world. From the comments I heard, the meeting and the Magic City shined nicely.

Meetings that go as successfully as NWA 2011 went don’t just happen. Planning for an event like this takes meticulous attention to the smallest of details (most details are small until overlooked; then they’re not small anymore!). Making NWA 2011 work took a lot of devotion, time and effort. From people in professional careers related to weather to people with no formal connection at all (just a love and passion for weather), a lot of people in our community helped make NWA 2011 a success.

If there’s any one person who deserves credit for pulling off such a wonderful conference, I know of no one who has put in more time and effort than self-admitted weather geek Bill Murray. He certainly didn’t do this for the money.

Bill’s passion for weather is so intense that he began the effort to bring NWA to Birmingham years ago (literally). This week, that work paid off. We should be grateful that we have movers and shakers like Bill in our community. Bill assembled a team of volunteers who helped with making sure events and presentations went off as smoothly as possible.

NWA 2011 has put our community on the world map for many, and one that will be remembered for years to come for the huge success it was.

Birmingham owes Bill a debt of gratitude.

NASA Spacecraft Sees Tornado Tracks

| May 17, 2011 @ 8:39 am | 6 Replies

Even from 438 miles above the Earth, you can tell that something very significant happened around Tuscaloosa and Birmingham April 27th.

For the first time, an energy-sensing instrument aboard a NASA spacecraft has been used to identify tracks left by the devastating tornado that tore through central Alabama.

Here’s what the damage path looks like as seen by ASTER, short for Advanced Spaceborne Thermal Emission and Reflection Radiometer:

ASTER tornado track

ASTER, which flies aboard NASA’s Tera spacecraft, monitors visible and infrared energy reflected from the Earth’s surface. The destruction caused by the tornado shows up clearly in ASTER’s imaging, because of differences in how energy reflects back to the spacecraft from areas where houses and trees have been demolished.

The image above was captured May 4th, while Tera—which has a near polar orbit—made a pass over central Alabama.

Sometimes, knowing exactly where a tornado was on the ground can be difficult to pinpoint.

ASTER’s imaging is one more way we can use technology to better identify what’s happening on Earth.
