The WindLog is a compact wind data logger designed to accurately measure and record wind speed, direction, and gust for optimizing turbine placement and performance. Includes WindSoft free software package to generate statistics, graphs, and reports.

The WindLog samples data every second and stores both average and gust readings at the user-selected interval. User selectable logging intervals range from 1-minute to 1-hour. The 2 MB memory can record for over three months at a 1-minute rate and store over a year’s worth of wind data at a 10-minute logging interval.

The Mini-Aervane wind sensor is equipped with low friction race bearings. This reduces the threshold to approximately 1 mile per hour. The wind direction sensor has a 16-point resolution. Logged direction readings are averaged readings.

The data logger operates on 3 AA Alkaline or Lithium batteries. Batteries are not included. Lithium batteries are recommended for cold environments. The typical life should be around six months. When connected to a computer, the WindLog will use the USB ports power to run, further extending the battery life. The WindLog ships with a 15-foot USB cable. A USB extender is available that will allow you to extend this cable to 100-foot using CAT5e network cable.

Each WindLog ships with a free Windows-based application, WindSoft. The software uses an SQLite database to track and record wind information. While connected, WindSoft will update the database every minute. Downloaded data is integrated into the database. By combining both logged and real-time data, the WindLog can be used both online and offline. It also can export CSV files for use with Microsoft Excel or any other application that supports CSV files.

The WindLog includes a support mast that can be used with the RainWise Mono Mount and Tripod. The mast may also be attached to a support structure using U-bolts or lag screws.

RainWise Weather Stations, Telemetry And Accessories

RainWise is one of the oldest players in the weather monitoring market, having been around since 1974. For reference, that’s only 4 years younger than the U.S. Environmental Protection Agency. Through the years this Maine-based company has logged several advancements in the field starting with RainWise’s very first product, the tipping bucket rain gauge, which is now an industry standard. Since then they have introduced the first consumer digital weather station and the first wireless consumer weather station among other pioneering innovations. With more than 40 years of experience, the products that RainWise produces today are just as inspired.

Data-Driven Decisions: Tracking Sediment during the Klamath Dam Removal

The largest dam removal in U.S. history, the deconstruction of the Klamath Dam is slated to begin this summer. The project includes four dams along the Klamath River with the first and smallest dam, Copco #2, scheduled for removal first. As each of the dams are torn down, scientists and consultants will keep a close eye on the state of the Klamath River downstream to assess the impact of undamming the river. Shawn Hinz, managing partner and environmental toxicologist with Gravity Consulting , has been involved with the Klamath Dam project for over a decade. Hinz was a part of these earlier steps, representing the academic stakeholder position as a graduate student sitting on a board of other stakeholders.

From the Tap: Source Water Monitoring for Public Health

In regions with historically secure access to clean drinking water, few think about the work that goes into ensuring that the water they fill their cups with is safe. In reality, millions of dollars are invested in the infrastructure, equipment and teams involved in converting source water into drinking water. While all the work that goes into providing clean water often goes unnoticed, analysts like Michele Gilkerson, a water research analyst with the City of Columbus Division of Water, know exactly how much goes into securing safe water for millions of people. Gilkerson started with Battelle Memorial Institute in 1991 in their water ecology section. There, she saw how interesting source water monitoring could be, even though it isn’t often spotlighted in the environmental sector.
