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.

Tides and microbes transform nitrogen where streams and the ocean meet
Enormous amounts of excess nitrogen hit water bodies all over the globe, including the U.S., due to runoff from agricultural and other human activities. This nitrogen can cause dead zones and harmful algal growth. Before it reaches the ocean, microbes can process and remove some of it from stream sediments, connected aquifers and tidal freshwater zones. Thanks to this process, coasts can have a decreased likelihood of harmful algal blooms. Keeping coastal waters clean is important for many reasons, including the fact that about 60% of the U.S. population lives on coasts. But despite the importance of these nitrogen processes, researchers have not fully investigated how they work.

Climate, nutrients and the future of hypoxia in a Chesapeake Bay tributary
The Chesapeake Bay is the site of recurring seasonal dead zones: areas of low dissolved oxygen where aquatic life struggles to survive if it can at all. In 2020, a dead zone in the Maryland portion of the bay was one of the smallest since 1985, when record keeping began. The hypoxic area in the Virginia portion of the bay was smaller and briefer than many years previous. But the problem isn’t gone yet, and looking forward, climate change will play a big role in determining the size and severity of dead zones throughout the bay. It could make it harder to get hypoxia under control in some places.
