Boundary Layer Network


Real-time Profiles of the Atmosphere’s Most Turbulent Layer, Observations of the boundary layer, from the ground up to about 3,000 feet, are critically important to the accuracy of atmospheric forecast models and severe weather forecasts and warnings issued by meteorologists. But existing sensors are limited in space and time, and insufficient to support the growing data requirements for improved forecasts at local scales, such as those desired by the renewables, utilities, aviation, air quality and water management industries.

The Earth Networks Boundary Layer Network (ENBLN) is the first monitoring network for the continuous collection of data within the planetary boundary layer and up to around 30,000 feet. Earth Networks is partnering with Boulder, Colorado-based Radiometrics Corporation to deploy the initial network of 10 thermodynamic profiling radiometers in California. The ENBLN is expected to grow quickly to 100 or more instruments across the United States providing round-the-clock temperature, humidity and liquid profiles of the boundary layer and above.

Earth Networks will combine observations from the ENBLN with information from its global weather network of more than 10,000 weather stations to improve mesoscale forecasts, including forecasts of high-impact local weather, and storm warnings across a variety of sectors.

Data Where and When It Matters Most

Existing boundary layer observations are limited in their spatial and temporal resolution. They primarily consist of radiosonde balloons usually released twice a day and which drift as they rise, commercial aircraft soundings, radar, and a small number of wind profilers on tall towers. The ENBLN will provide consistent and continuous temperature, humidity and liquid profiles of the boundary layer and above, updated every minute and collected from fixed locations selected to yield the most benefit to industry and society.

Convective Initiation

Improved monitoring of critical stability parameters will provide insight into the initiation of convective storms, one of the priorities of the U.S. National Weather Service. ENBLN data will combine with data from Earth Networks’ existing networks to enhance severe weather warnings.

Atmospheric Instability

ENBLN data will provide improved information about the instability of the atmosphere, such as that produced by heating of the surface, strong winds and rough or hilly terrain. This data is particularly useful for utilities, wind-power forecasting and air quality managers.

Suspended Liquid Data

Continuous observations of the amount and temperature of liquid in the atmosphere will provide valuable data for the utilities, solar-power forecasting, aviation and water management industries.

State-of-the-Art Radiometers

Rugged, portable radiometers from Radiometrics, the leader in thermodynamic profiler sensing technology, deliver continuous data with radiosonde-equivalent assimilation accuracy. Mature software generates a full suite of forecast tools and indices in familiar meteorological format.
