On every utility-scale solar farm, it’s crucial to answer the fundamental question: how much solar radiation reaches the surface of the photovoltaic (PV) modules? These farms span hundreds of acres and in order to address this question, owners use meteorological monitoring stations and data loggers...

To help environmental researchers who measure solar radiation improve their measurements and simplify their lives, Campbell Scientific and Apogee Instruments teamed up to develop a new sensor. This new sensor combines features from higher-end blackbody thermopile pyranometers and lower-end silicon photocell pyranometers. The CS320 Digital Thermopile...

Have you ever heard someone mention "ET" and wondered what it meant? Assuming the person wasn’t talking about extra-terrestrials or Entertainment Tonight, the conversation was probably about evapotranspiration. Evapotranspiration (or "ET") is the water lost through plant transpiration and soil and plant evaporation. The images...

Solar radiation is an important measurement for many researchers and those who are monitoring their evapotranspiration values for irrigation purposes. If you have been wondering how accurate your solar radiation measurement is, Apogee Instruments (an associated company of Campbell Scientific) has a Clear Sky Calculator mobile...
