JeTSI to Participate in NOAA’s 2017 Satellite Conference

JeTSI will be presenting a poster at NOAA’s 2017 Satellite Conference at the City College of New York, July 17 – 20. The poster will demonstrate a new approach to the Research-to-Operations (R2O) algorithm life cycle that leverages commodity cloud services, agile algorithm development, and open access to NOAA observational assets. Built around rigorous algorithm architecture models, an open algorithm development API and a scalable algorithm execution architecture, the “Open R2O Architecture” significantly reduces the cost of entry to perform basic research, provides high-throughput product generation services, and provides value-added end-user services.

The poster, “Open R2O Architecture – Reducing the Cost of Entry for Science Applications,” by Dr. Stephen Marley and Patrick Barnes, JeTSI, will be viewable on our website after the conference.

JeTSI at NoMagic World Symposium

JeTSI Modelers attended the NoMagic World Symposium.

JeTSI has been on the forefront of applying Model Based Systems Engineering (MBSE) services and products utilizing the Department of Defense Architectural Framework (DoDAF) on large aerospace projects.  We have been working with NASA and NOAA on the Joint Polar Satellite System (JPSS) Ground Project (GP) since 2010. The JPSS GP spans the globe, with two Ground Terminal sites on each pole, plus communications provided by NASA’s Space Network geosynchronous communications satellites. The JPSS GP has numerous interfaces to other weather programs, NASA support organizations, other NOAA entities, other civil agencies and elements of the Department of Defense.

Leveraging UPDM, JeTSI worked with NASA to develop a very complete and detailed model of the JPSS GP. This architecture allowed NASA to execute its technical management activities with minimal resources, and to communicate the systems concepts and nuances throughout the life cycle. The full benefit of this work will be realized when the JPSS-2, JPSS-3, and JPSS-4 satellites are deployed over the next decade without having to re-develop the technical baseline for each new deployment.

JeTSI also leveraged the JPSS GP architecture to assist NOAA’s Office of Satellite Ground Services (OSGS) in charting the overall NESDSIS ground system architecture into the next decade. For both NASA and NOAA, JeTSI has been in a unique position to support major system trades (capability, cost, and schedule) as NOAA charts its new course into the future of weather satellites.

Rip Current Survival Guide

As you start heading out to the beaches, be sure you know how to identify and survive a rip current!

Rip currents are channelized currents of water flowing away from shore at surf beaches. Typically, they form at breaks in sandbars, and also near structures, such as jetties and piers, as well as cliffs that jut into the water. Rip currents are common and can be found on most surf beaches, including the Great Lakes and Gulf of Mexico.

How to Survive a Rip Current:

  • Don’t fight the current. It’s a natural treadmill that travels an average speed of 1-2 feet per second, but has been measured as fast as 8 feet per second—faster than an Olympic swimmer.
  • Relax and float to conserve energy. Staying calm may save your life.
  • Do NOT try to swim directly into to shore. Swim along the shoreline until you escape the current’s pull. When free from the pull of the current, swim at an angle away from the current toward shore.
  • If you feel you can’t reach shore, relax, face the shore, and call or wave for help. Remember: If in doubt, don’t go out!

Hurricanes – Be Prepared!

Hurricanes season runs from June 1 to November 30 each year. Over a typical 2-year period, the U.S. coastline is struck by an average of 3 hurricanes, 1 of which is classified as a major hurricane (winds of 111 mph or greater).

Plan ahead and be prepared!

While hurricanes pose the greatest threat to life and property, tropical storms and depression also can be devastating. The primary hazards from tropical cyclones (which include tropical depressions, tropical storms, and hurricanes) are storm surge flooding, inland flooding from heavy rains, destructive winds, tornadoes, and high surf and rip currents.

  • Storm surge is the abnormal rise of water generated by a storm’s winds. This hazard is historically the leading cause of hurricane related deaths in the United States. Storm surge and large battering waves can result in large loss of life and cause massive destruction along the coast.
  • Storm surge can travel several miles inland, especially along bays, rivers, and estuaries.
  • Flooding from heavy rains is the second leading cause of fatalities from land falling tropical cyclones. Widespread torrential rains associated with these storms often cause flooding hundreds of miles inland. This flooding can persist for several days after a storm has dissipated.
  • Winds from a hurricane can destroy buildings and manufactured homes. Signs, roofing material, and other items left outside can become flying missiles during hurricanes.
  • Tornadoes can accompany land falling tropical cyclones. These tornadoes typically occur in rain bands well away from the center of the storm.
  • Dangerous waves produced by a tropical cyclone’s strong winds can pose a significant hazard to coastal residents and mariners. These waves can cause deadly rip currents, significant beach erosion, and damage to structures along the coastline, even when the storm is more than 1,000 miles offshore.

When a hurricane threatens your community, be prepared to evacuate if you live in a storm surge risk area. Allow enough time to pack and inform friends and family if you need to leave your home.

  • Secure your home: Cover all of your home’s windows. Permanent storm shutters offer the best protection for windows. A second option is to board up windows with 5/8 inch exterior grade or marine plywood, built to fit, and ready to install. Buy supplies before the hurricane season rather than waiting for the pre-storm rush.
  • Stayed tuned in: Check the websites of your local National Weather Service office and local government/emergency management office. Find out what type of emergencies could occur and how you should respond. Listen to NOAA Weather Radio or other radio or TV stations for the latest storm news.
  • Follow instructions issued by local officials. Leave immediately if ordered!
  • If NOT ordered to evacuate:
    • Take refuge in a small interior room, closet, or hallway on the lowest level during the storm. Put as many walls between you and the outside as you can.
    • Stay away from windows, skylights, and glass doors.
    • If the eye of the storm passes over your area, there will be a short period of calm, but at the other side of the eye, the wind speed rapidly increases to hurricane force winds coming from the opposite direction.

Environmental Information in Every Decision – EUMETSAT

EUMETSAT, the European Organisation for the Exploitation of Meteorological Satellites, Conference is being held this week in Darmstadt, Germany bringing together meteorologists, scientists and researchers from around the world to share their experience and knowledge during plenary, poster and workshop sessions.

Presenting in Poster Session 1, “Environmental Information in Every Decision” by Philip Ardanuy (INNOVIM), David Green (NASA Applied Sciences Program Office), George Komar (NASA Earth Science Technology Office), Dr. Stephen Marley (JeTSI), Peter Neilley (The Weather Business), and Carl Schueler (Schueler Consulting).

In two decades, nearly-deployed constellations of US/European polar-orbiting and geosynchronous meteorological/environmental satellite systems will approach the end of their planned operational lifetimes. As the needs of weather services users continue to grow, they demand a broader suite of applied environmental services. Our ability to deliver these enhanced services is directly coupled to the pace and state of technology maturation. The poster depicts several classes of decisions (public/private; corporate/ commercial; real-time/tactical/strategic) and how intersections of technology maturation and evolving societal needs can drive concepts for exploitation of emerging technologies for, and data collected from, a future satellite observing systems generation.
