Overview
The RM Young wind monitor is a field proven, high performance wind sensor. The wind speed sensor is a four blade helicoid propeller. Propeller rotation produces an AC sine wave voltage signal with frequency directly proportional to wind speed. Slip rings and brushes are eliminated for increased reliability.
Mechanics
The wind direction sensor is a rugged yet lightweight vane with a sufficiently low aspect ratio to assure good fidelity in fluctuating wind conditions. Vane angle is sensed by a precision potentiometer housed in a sealed chamber. With a known excitation voltage applied to the potentiometer, the output voltage is directly proportional to vane angle. A mounting orientation ring assures correct realignment of the wind direction reference when the instrument is removed for maintenance.
Durable
The instrument is made of UV stabilized plastic with stainless steel and anodized aluminum fittings. Precision grade, stainless steel ball bearings are used. Transient protection and cable terminations are in a convenient junction box. The instrument mounts on standard 1" pipe.
Models
The Wind Monitor is available with two additional output signal options. Model 05103V offers calibrated 0-5 VDC outputs, convenient for use with many data loggers, including the NexSens iSIC data logger. Model 05103L provides a calibrated 4-20 mA current signal for each channel, useful in high noise areas or for long cables (up to several kilometers). Signal conditioning electronics are integrated into the sensor junction box.

Village Green Project builds air quality awareness with monitoring park bench
The U.S. Environmental Protection Agency is on a mission to make air quality monitoring cheaper, easier and more accessible through the implementation of innovative new monitoring stations. The Village Green Project is a new initiative from the EPA that seeks to increase the scope of air quality monitoring by seamlessly incorporating monitoring devices into community settings. Led by Gayle Hagler, an environmental engineer at the EPA Office of Research and Development, an EPA design team has constructed a prototype that combines the ability to monitor ozone and fine particulate matter as well as wind speed, wind direction, temperature and humidity all into the functional design of a park bench.

UNC's industry-standard water quality profiling platforms get upgrade
The University of North Carolina Institute Of Marine Sciences has a history with profiling platforms. UNC engineers and scientists have been building the research floaters for 10 years in a lab run by in Rick Luettich, director of the institute. UNC scientists and engineers developed their own autonomous vertical profilers to take water quality readings throughout the water column. They have three profilers placed in the New and Neuse rivers. The profilers are designed to drop a payload of sensors to an allotted depth at set time intervals. Instruments attached take readings continuously on the way down and up. Data collected by the profilers has been used to study water related issues such as infectious disease and sediment suspension.

USGS weather station network monitors Arctic Alaska's climate
When the U.S. Geological Survey began building their climate and permafrost monitoring network in Arctic Alaska in 1998, there wasn't much precedent for how to build the infrastructure for the instruments in the region's unforgiving environment. That meant the scientists had to learn the particulars on the fly. For example: On the great expanse of flat, barren tundra, a weather station sticks out like a sore thumb to a curious grizzly bear. "The initial stations were pretty fragile," said Frank Urban, a geologist with the USGS Geosciences and Environmental Change Science Center. "So the bear and those stations--the bear won every single time without any problem.
