NASA has awarded a sole source contract to the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder for the Total and Spectral Solar Irradiance Sensor-2 (TSIS-2).

Researchers in Denmark claim to have identified the best locations for rear plane-of-array irradiance sensors on the back of single-axis trackers in bifacial PV projects. Their work suggests how to ...

Due to a drop in number of sunspots and the resulting decrease in total solar radiance (TSI) values, NASA launched a new sensor to study the dimming sun. Data from NASA’s Spaceweather website showed ...

For Jeff Privette, a scientist at the National Oceanic and Atmospheric Administration's National Climatic Data Center, 2011 was not a great year. Privette keeps track of climate sensors on satellites ...
