Overview
The RM Young 43502 shield employs a triple-walled intake tube and multiple canopy shades to isolate the sensor from precipitation and solar radiation. A continuous-duty blower draws ambient air through the intake tubes and across the sensor, minimizing radiation errors. Compact shield components reduce radiation absorption and improve aspiration efficiency. Specially selected plastic materials provide high reflectivity, low conductivity, and maximum weatherability.
Design
The versatile DC blower is designed for continuous duty of more than 80,000 hours (9 years) at 25 degrees C (77 degrees F). Brushless electronic commutation is achieved using dependable solid state circuitry.

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.

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.

Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question. 
 
[caption id="attachment_38996" align="alignnone" width="940"] HRWC volunteers measure stream velocity across a subsection of Woods Creek, a tributary of the Huron River near Belleville, Michigan. Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.
