A lightning strike nearby may induce a high voltage surge, which the integral transient suppressor of the instrument may not tolerate. Therefore, additional protection is needed, especially where frequent and severe thunderstorms are common and where long cables of more than 30m are used. The WSP150 offers three-stage protection against surge currents up to 10 kA entering through the power and signal cables.
The Vaisala WSP150 Surge Protector has four channels, two of which are dedicated to power lines and two for data lines. Each channel uses a three-stage protection scheme as follows: first there are discharge tubes, then voltage dependent resistors (VDR), and finally transient zener diodes. Between each stage, there are either series inductors or resistors. Both differential and common mode protection is provided for each channel: across the wire pairs, against the operating voltage ground, and against the earth. The WSP150 also includes noise filtering against HF and RF interference.
Vaisala recommends using the WSP150 when wind and weather instruments are installed on top of high buildings or masts and in open grounds, that is, anywhere with an elevated risk of lightning. Also use the WSP150 if your cable length exceeds 30m or you have unshielded, open-wire lines.

Vaisala WXT520: Weather station designed with monitoring systems in mind
The world’s weather is full of surprises. That makes a quality weather station a valuable piece of technology for monitoring systems. Vaisala's WXT520 multiparameter weather station is built with monitoring systems in mind. It monitors six weather parameters in real time, so users have the numbers on an unexpected rain storm or turbulent wind event. It can be a means of understanding weather events that caused a flush of nitrogen into a river or low water levels in a lake. What’s more, with the help of a data logger and telemetry system, it can deliver that information to one’s desk so she can stay dry and keep an eye on the data during a storm. Three core components make up Vaisala’s WXT520 weather station.

Restoration, Testing, Research and Education
A few years after Ohio became a state in 1803, George Harner arrived in Greene County with a land deed signed by then-President Thomas Jefferson and Secretary of State James Madison. The homestead was largely old forest and wetlands and also included a fen-fed stream—the Beaver Creek. As was the case with much of the Ohio Territory, the forests eventually gave way to land clearing and grain farming. Harner’s descendants, including his son John and John’s wife, Sarah Koogler, continued to work the rich soil for many years to follow. Much of the original property and surrounding land has fallen prey to urban sprawl.

Storms Cause Extended, Elevated Contaminant Concentrations in Urban Streams
Each fall in Puget Sound, coho salmon leave the salt water and swim up freshwater streams. They head upstream to spawn: lay their eggs and die. Death is always the end of this journey for coho salmon, but in streams now running through urban areas, stormwater runoff kills them before they can spawn. This phenomenon, called Urban Runoff Mortality Syndrome, can kill up to 70-90% of coho salmon in an affected area. “‘Woah’ is a pretty common response,” said Kathy Peter, a research scientist formerly at University of Washington Tacoma and the Center for Urban Waters. This phenomenon adds pressure to the Puget Sound population, already considered a species of concern by the United States Fish and Wildlife Service under the Endangered Species Act.
