NOAA’s National Weather Service and Honeywell Aerospace Technologies have signed a two-year cooperative research and development agreement to deploy a High-Altitude Lidar Atmospheric Sensing (HALAS) ground system and to evaluate the upper-air data gathered to determine if it could aid in weather forecasting.
Honeywell’s HALAS ground system uses a rapid series of laser pulses to provide near-real-time atmospheric measurements. HALAS enables forecasters to obtain weather data up to 100,000ft above the surface of the Earth, though NOAA meteorologists intend to focus on data below 40,000ft, where aircraft fly and the atmosphere is more dynamic. HALAS will gather observations including atmospheric pressure, temperature, humidity and wind speed and direction, similar to weather balloons.
“Understanding the atmosphere above the surface is vital to predicting the evolution of weather phenomena, from local afternoon thunderstorms to expansive blizzards and hurricanes,” said Jordan Gerth, meteorologist at National Weather Service Office of Observations. “This research project could help us identify a new way to gather the observations we need, more readily.”
Matt Picchetti, vice president (VP) general manager (GM) of navigation and sensors at Honeywell Aerospace Technologies, said, “Honeywell’s High-Altitude Lidar Atmospheric Sensing (HALAS) is a remotely-operated, ground-based weather information system that provides near-real-time, high-altitude atmospheric measurements in as little as three minutes.”
Under the CRADA (co-operative research and development agreement), NOAA and Honeywell will: evaluate the utility of the HALAS ground system for NOAA’s observational needs, particularly as an operational observation in support of the National Weather Service; develop an on-site demonstration of the HALAS system for data analysis and assessment; and explore value creation, cost savings, data rights and sharing models if a long-term network of HALAS systems can meet NOAA’s mission.
The HALAS ground system for this research project will be located on the property of the National Weather Service Baltimore-Washington Weather Forecast Office in Sterling, Virginia. Technicians will design a fixed HALAS installation prototype that could be used for potential expansion and deployment of HALAS at additional forecast offices.
NOAA regularly partners with private sector companies through CRADAs to conduct research and development work that is mutually beneficial and helps to accomplish NOAA’s mission.
