The weather page reports the 10-meter high wind speed and direction. The instrument is a R.M. Young Model 05103. We are using a Campbell CR-10X data logger. A pyranometer is an instrument for measuring solar radiation received from a whole hemisphere. It is suitable for measuring global sun plus sky radiation.
Solar radiation varies significantly among regions.
Season and time of day are major considerations, but surrounding terrain elevation, man-made obstructions, and surrounding trees can also cause large variations in locations of a small area. The LI-200SA is used extensively in meteorological studies, passive solar system analysis, irrigation scheduling, hydrologic studies and many other environmental studies. For clear unobstructed daylight conditions, the LI-200SA compares favorably with first class thermopile pyranometers. We use a LiCor model LI-190SA quantum sensor.
