Irradiance Observations
ASD has several types of foreoptics for irradiance measurements. These
include:
• In-air cosine corrected receptors for measurement of total irradiance
• Accessories for measurement of direct irradiance
• Under-water cosine corrected receptors for measurement of in-water up-
and down-welling irradiance.
