The NexSens G2-RAIN Alert System is a self-contained rain monitor with an integrated precision rain gauge and real-time data alerts. It transmits accurate rainfall measurements directly to WQData LIVE’s cloud based data management platform using internal power and an embedded cellular modem. Paired with WQData LIVE’s configurable alerts, users are notified of rain events directly on a mobile device or computer. Historical rain data can be viewed, graphed, and downloaded from WQData LIVE for additional analysis.

Integrated tipping bucket and MAST mount features create an easy to setup and simple to maintain monitoring system which can be installed and relocated in minutes. Devices can be configured directly from any web browser without the need for costly site visits and complicated connections.

The G2-RAIN’s included Tipping Bucket Rain Gauge with Siphon, uses a standard 8” (200mm) diameter receiver that adheres to WMO & NOAA criteria. The siphon allows a steady flow of water to the tipping mechanism in order to provide reliable readings in 0 to 27” (700mm) per hour rain conditions. The collector funnel comes with a stainless steel filter screen to reduce manual maintenance by preventing leaves and other debris from clogging the opening.

*To ensure reliable data transmission, confirm the availability of Verizon 4G service at deployment location.

Utah’s Canyonlands Research Center: A Great Study Location for Climate Effects on Ecosystem Processes, Community Dynamics and More

Canyonlands Research Center (CRC) is situated at The Nature Conservancy’s Dugout Ranch , over 5,200 private acres of research study area. One of CRC’s primary roles is to facilitate research and monitoring work of university and federal researchers. CRC is located adjacent to Canyonlands National Park , which extends over more than 337,000 acres of public land. CRC also partners with many organizations, including the Bureau of Land Management, USFS, NPS, USGS, Utah State University, and the Utah Division of Wildlife Resources to identify the most pressing research needs in this region.

“WireWall” Measuring Flood Risk in Real Time

This past winter, physical oceanographer Jenny Brown and her team at the National Oceanography Centre (NOC) , United Kingdom, were trialing a new concept: “WireWall” with colleagues at HR Wallingford. This new system for measuring wave hazard at sea walls allows managers to understand flood risk for existing coastal structures better, and Dr. Brown spoke to EM about the system and what inspired it. “Traditional sensors don’t work in spray conditions,” explains Dr. Brown. “We’ve got a lot of oceangoing sensors that measure currents, water depths, all sorts of information, but the second you put them on land and out of solid water, they don’t work, often because they’re acoustic systems.

A Conversation With Mika McKinnon, Freelance Scientist

So much of what many field scientists and engineers do hinges upon their ability to communicate the value of their work. Communicating the value of science, generally, is part of that process—one that Mika McKinnon has down cold. We spoke with geophysicist Mika McKinnon about her work as a freelance scientist, and what it's like to do work that touches on science communication in so many areas. Freelance science and doing disasters At first blush, what Mika McKinnon actually does might seem confusing. “No, no, I swear, freelance scientist, real job,” quips Ms. McKinnon. “I often describe myself as having a non-linear career path.
