Calibration of a Solar Absolute Cavity Radiometer with Traceability to the World Radiometric Reference (Paperback) (ISBN-13: 9781249196839)

This report describes the present method of establishing traceability of absolute cavity radiometers to the World Radiometric Reference (WRR) through the proces employed in the International Pyrheliometer Comparisons (IPC). This method derives the WRR reduction factor for each of the participating cavity radiometers. An alternative method is proposed, described, and evaluated as a way to reduce the uncertainty in the comparison process. The two methods are compared using a sample of data from the recent IPC-VIII conducted from September 25th to October 13th, 1995 at the World Radiation Center in Davos, Switzerland. A description of absolute cavity radiometers is also included, using a PMO-6 as an example of active cavity radiometers, and a HF as an example of passive cavity radiometers.
