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.

From Pans to Buoys: Advancing Reservoir Evaporation Rate Monitoring in Texas
In warmer climates like Texas, high reservoir evaporation rates can lead to declines in water level and water availability during droughts, making monitoring essential in order to ensure water security during times of scarcity. According to the Texas Water Development Board (TWDB), evaporation rates in Texas were previously based on data collected from a sparse network of Class A evaporation stations, dating back to the 1960s. These pans were stationed near reservoirs and still remain a widely accepted standardized approach to measuring evaporation rates on land. Monthly pan-to-lake coefficients were developed in the 1980s to connect the data collected from the pans to known lake conditions, extrapolating evaporation rates of the lakes using the pan data.

A Drop in the Ocean: Restoring London’s Tidal Thames
The United Kingdom has grappled with wastewater management problems for decades. Although sewage treatment in the 20th century allowed many rivers, including the tidal Thames, to have healthy fish populations, combined sewer overflows into rivers–most commonly during heavy rainfall–affected water quality and occasionally even killed fish. Problems reached a head in 2012 when multiple infractions of European urban wastewater treatment laws threatened costly fines, on top of the environmental cost of repeated sewage spills into British rivers. Fast forward to 2025, and after a decade of construction work, London’s Thames Tideway Tunnel , affectionately dubbed the “super sewer”, is now fully activated and ready for testing.
