Spring Weather

We all anticipate spring weather eagerly looking forward to warmer weather, blooming gardens, and outdoor activities. But spring can also be temperamental and bring its own weather challenges – Tornadoes, Thunderstorms, Flooding, and Hurricane Season starts June 1!

To help you better understand Hurricanes and prepare, we are reposting our Hurricane Preparedness article from last year.

Kudos to Emily for working with her class and her mom to make an emergency plan and be prepared!! She asked JeTSI to share a great site created for kids  –

So like Emily and her mom….  Be Prepared! Make a family plan in case of a natural or national disaster.

Spring Weather Hazards

Warnings vs Watches

  • Warnings mean a weather event is occurring – take action!
  • Watches mean conditions are favorable for a weather event – be prepared!

JeTSI at AMS 2018

JeTSI team member, Patrick Barnes presented the poster, “Utilizing MBSE to Modularly Architect the NESDIS Ground Enterprise” at the American Meteorological Society’s 14th Annual Symposium on New Generation Operational Environmental Satellite Systems . The power of Model-Based Systems Engineering (MBSE) lies in the relationships built between the systems, activities, and functions within the model. Rather than a flat, two-dimensional view, MBSE allows for interweaving relationships in architecting a system of systems. The model can be updated to keep it current, and linked as a subset to a larger architectural model providing a view of the total enterprise.

This poster shows the JPSS ground system as a subset in the larger NOAA NESDIS ground architecture model. The NESDIS Ground System consists of segregated systems, operations, networks, and facilities. This amalgamation of systems and system of systems is often referred to as the NOAA “stovepipes.” With the transition of GOES-16 and JPSS-1 operations to NOAA, we will see an increase in the complexity of the overall NESDIS Ground System. The addition of hundreds of systems, servers, and network nodes make understanding the system as a whole a daunting task. Modern architecture tools and disciplines, such as Model-Based Systems Engineering, can be used to clearly define the as-is state of a ground system regardless of complexity.

The poster is viewable in Published Papers on the JeTSI website.

Winter Weather is Here!

Are you prepared for Winter Weather?

Do you know the difference between a Winter Storm Watch, Winter Storm Warning and a Winter Weather Advisory?

  • When a warning is issued: TAKE ACTION!
  • When a watch is issued: Get Prepared!
  • When an advisory is issued: Take Precautions!

Review Winter Weather Safety with your family to better understand the weather and to be prepared.

Will there be rain, ice, or snow???

Bundling up in layers and staying dry is one of the best things you can do to stay safe this winter.


JPSS-1 Launch A Success!

The Joint Polar Satellite System-1 lifted off from Vandenberg Air Force Base, California, at 1:47 a.m. PST November 18, 2017. The satellite’s next-generation technology will help improve the timeliness and accuracy of U.S. weather forecasts three to seven days out.

For more information on the launch:



JPSS-1 Launch

The second attempt to launch NOAA’s JPSS1 satellite on November 15 at 1:47 am was scrubbed due to excessive upper level winds. The team is assessing their options.

JPSS will bring the latest and best technology NOAA has ever flown in a polar orbit to capture more precise observations of the atmosphere, land and waters. JPSS-1, which will be known as NOAA-20 when it reaches orbit, will join Suomi NPP, the joint NOAA-NASA weather satellite, giving the U.S. the benefit of two, sophisticated polar satellites in the same orbit. Each will circle the globe 14 times a day, 50 minutes apart and provide full, global observations for U.S. weather prediction. Forecasters will use the data to better predict weather events and hazards, such as a hurricane’s track, and when a hurricane will intensify or weaken, identify power outages and locate and evaluate damage after a storm.

Earthquakes – Be Prepared!

Know what to do if an earthquake strikes and be prepared ahead of time. Take part in the Great ShakeOut Earthquake Drills, part of America’s PrepareAthon.

In MOST situations, you will reduce your chance of injury if you Drop, Cover, and Hold On:

DROP where you are, onto your hands and knees. This position protects you from being knocked down and also allows you to stay low and crawl to shelter if nearby.

COVER your head and neck with one arm and hand

  • If a sturdy table or desk is nearby, crawl underneath it for shelter
  • If no shelter is nearby, crawl next to an interior wall (away from windows)
  • Stay on your knees; bend over to protect vital organs

HOLD ON until the shaking stops.

  • Under shelter: hold on to it with one hand; be ready to move with your shelter if it shifts
  • No shelter: hold on to your head and neck with both arms and hands.

Continue to read for further recommended earthquake safety actions.

Prepare in advance!

Steps to Prepare, Survive, and Recover

  • Secure your space
  • Prepare a disaster plan
  • Prepare a communication plan
  • Have a personal and household disaster supply kit
  • Organize important documents in a grab and go bag
  • Prepare for reconnecting and recovery

Countdown to JPSS-1 Launch

The Joint Polar Satellite System-1, the first in a new series of highly advanced NOAA polar-orbiting satellites, is scheduled to lift off Nov. 10, at 1:47 a.m. PST from Vandenberg Air Force Base, California.

“The new JPSS satellite will join GOES-16 as we are confronting one of the most tragic hurricane seasons in the past decade,” said Secretary of Commerce Wilbur Ross. “The JPSS satellite system will provide advanced forecasting on not only hurricanes, but also dangerous weather events threatening communities across the United States.”

The satellite, called JPSS-1, will provide meteorologists with a variety of observations, such as atmospheric temperature and moisture, sea-surface temperature, ocean color, sea ice cover, volcanic ash and fire detection. Forecasters will be able to use the data to better predict weather events and hazards, such as a hurricane’s track, and when a hurricane will intensify or weaken, as well as identifying power outages in addition to locating and evaluating damage following a storm.

Circling the globe 14 times a day

JPSS-1, which will be known as NOAA-20 when it reaches polar orbit, will join the Suomi National Polar-orbiting Partnership (Suomi NPP), a joint NOAA-NASA weather satellite, giving the U.S. the benefit of two, sophisticated polar satellites in the same orbit. Each will circle the globe 14 times a day, 50 minutes apart and provide full, global observations for U.S. weather prediction. After it successfully clears the on-orbit test phase, NOAA-20 will become the nation’s primary polar weather satellite and Suomi NPP will become its back up.

“Having two advanced polar satellites in the same orbit will ensure our numerical weather models have the necessary, critical data to support forecasts up to seven days ahead of extreme weather events,” said Stephen Volz, Ph.D., director of NOAA’s Satellite and Information Service.

“Eighty-five percent of the data flowing into our weather forecast models come from polar-orbiting satellites, such as Suomi NPP and the new JPSS series,“ said Louis W. Uccellini, Ph.D., director of NOAA’s National Weather Service. “Using polar satellite data, we have been able to provide emergency managers with more accurate forecasts, allowing them to pre-position equipment and resources days before a storm. JPSS will continue this trend.”

Major Upgrade

The five next-generation instruments on JPSS will be a major upgrade from NOAA’s legacy polar-orbiting satellites. JPSS will provide more detailed information about atmospheric temperature and air moisture leading to more accurate near-term weather predictions. Over longer timescales, this data will help improve our understanding of climate patterns that influence the weather, such as El Nino and La Nina.

The JPSS program is a partnership between NOAA and NASA that will oversee all the satellites in the series. NOAA funds and manages the program, operations and data products. NASA develops and builds the instruments, spacecraft and ground system and launches the satellites for NOAA.

“The launch of JPSS-1 continues the strong, decades-long partnership between NOAA and NASA in developing state-of-the-art Earth observation satellites,” said Sandra Smalley, director of NASA’s Joint Agency Satellite Division. “We are proud to contribute to NOAA’s continued leadership in critical weather forecasting throughout the entire JPSS series.”

Ball Aerospace designed and built the JPSS-1 satellite bus, and Ozone Mapping and Profiler Suite instrument, integrated all five of the spacecraft’s instruments and performed satellite-level testing and launch support. Raytheon Corporation built the Visible Infrared Imaging Radiometer Suite and the Common Ground System. Harris Corporation built the Cross-track Infrared Sounder. Northrop Grumman Aerospace Systems built the Advanced Technology Microwave Sounder and the Clouds and the Earth’s Radiant Energy System instrument.

NASA-TV will cover the launch live and can be viewed at, starting at 1:15 a.m. PST on November 10.
