Overview
The Kipp & Zonen SMP Series Smart Pyranometers are high-quality radiometers designed for measuring short-wave irradiance on a plane surface (radiant flux, W/m²), which results from the sum of the direct solar radiation and the diffuse sky radiation incident from the hemisphere above the instrument.
Integration
SMP pyranometers feature internal digital signal processing and interfaces optimized for industrial data acquisition and control systems. Kipp & Zonen has developed a smart interface that features RS-485 Modbus data communication for connection to programmable logic controllers (PLC’s), inverters, digital control equipment and the latest generation of data loggers. Amplified Voltage or Current outputs are also included for devices that have high-level analog inputs or current loop interfaces.
Model Options
All models are available in two versions. One has an analog voltage output of 0 to 1 V, and the other has an analog current output of 4 to 20 mA. They all have a 2-wire RS-485 interface with Modbus (RTU) protocol. Digital signal processing provides faster response times and, with an integrated temperature sensor, corrects for the temperature dependence of the detector sensitivity.
Design
To achieve the required spectral and directional characteristics, SMP Series pyranometers use thermopile detectors and glass domes. All SMPs have built-in bubble levels and adjustable leveling feet. Snap-on sun shields reduce solar heating of the housings. The waterproof connectors have gold-plated contacts.

Bringing Fish Back: Reviving Britain’s Freshwater Habitats with the Wild Trout Trust
Freshwater covers less than 1% of the Earth’s surface but has an outsized impact on global ecosystems, supporting more than 10% of all known species, reports the World Wildlife Fund . Freshwater environments such as rivers and wetlands provide significant scientific, economic, and cultural value. But pressure from climate change, biodiversity loss, and a lack of prioritization in environmental policies mean freshwater habitats are recognized as one of the most threatened in the world–something scientists have dubbed an “invisible tragedy. ”

While human infrastructure, urbanization, and industrialization have advanced human societies, the natural environment has suffered due to constructed impediments and deteriorating architecture. In order to combat this degradation, habitat restoration programs across the US work to remove impairments and improve damaged waterways.

In the far north, the Alaska Peninsula stretches away from the Last Frontier into the Pacific Ocean. A narrow strip of land dotted with freshwater lakes and intruded upon by ocean inlets–this unique region is intimately connected with the surrounding water. 
 
Nestled halfway down the peninsula's southern coast are the small villages of Chignik. The area has historically been home to the Aleut people and has been heavily reliant on fishing for centuries. 
 
Home to commercial and subsistence fishing today, Chignik continues to rely upon the salmon returns to the surrounding villages, which are supported by scientists working tirelessly to understand and steward these fish populations.
