Description

The mean error is about 0.7 percent for the full range. For zenith angles up to 40° the error is much smaller. The largest error is for zenith angle of 80° and 85° and for tau greater than 5. The maximum error is about 7 percent. At these large angles and opacities, the error has a minor effect on the calculated daily insolations.
