Laser Ceilometer Measures 4 Cloud Layers At Once
Sacramento, CA - All Weather, Inc. announced the newest version of the Model 8339 Laser Ceilometer. Able to measure cloud height from 0 to 30,000 feet (9 km), the 8339 is the only ceilometer to penetrate to such heights using an eye-safe, low power, laser transmitter. The 8339 Laser Ceilometer is also the first to simultaneously detect and measure up to four layers of clouds, including the thickness of individual layers. Advanced digital signal processing algorithms ensure more accurate data measurements in any weather conditions and reduce the chance of false cloud rejection.
The 8339 Laser Ceilometer is the only ceilometer to output standard cloud information, such as vertical visibility, ground-based obscurations, and cloud base measurements, as well as the National Weather Service Sky Condition Algorithm, which provides information on sky coverage and variable ceilings.
"Airport weather sensors must be incredibly responsive to the latest changes in weather, regardless of the presence of ground fog or heavy precipitation," stated Gary Wagner, CEO of All Weather, Inc. "AWI has been designing and manufacturing laser ceilometers for the past 20 years and has installed more than 500 units around the world. The 8339's one-of-a-kind digital signal processing algorithms produce accurate readings in all weather conditions, including conditions which can cause serious errors in other ceilometers."
Advanced Digital Signal Processing
The 8339's advanced digital signal processing algorithms ensure the system provides highly accurate reporting of cloud base locations in all weather conditions. The system can discern extremely thin obscurations, with a resolution of 12.5 feet over the full range of the sensor. Both vertical visibility and ground-based obscurations can be reported while locating higher layers of clouds.
Eye-Safe Laser Technology
AWI's 8339 Laser Ceilometer uses the reliable and accurate Light Detection And Ranging (LiDAR) optical radar technology. An eye-safe, low-power laser transmits light pulses to the cloud base. Cloud height is measured by sophisticated signal processing of laser scatter as it propagates through aerosols.
Modular Design
The Model 8339 Laser Ceilometer is a compact, low maintenance unit based on a modular design. It includes a sophisticated array of built-in tests that execute in the background during operation. This allows for the detection of possible sensor errors and reports them to the operator, along with a reference to the appropriate field-replaceable module. No consumables are required, such as blower filters or desiccants, keeping maintenance to a minimum.
