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...

Are you concerned about frost damage to your crops?
There are a number of high-value crops that are critically vulnerable to frost damage. Especially on buds, flowers, and early fruit, frost can cost growers thousands of dollars per acre.
For a long time, many growers have monitored...
