Title: The Fifth SeaWiFS Intercalibration Round-Robin Experiment (SIRREX-S), July 1996
Published: October 01, 1999
Abstract: This report documents the fifth Sea-viewing Wide Field-of-view Sensor (SeaWiFS) Intercalibration Round-Robin experiment (SIRREX-5), which was held at the National Institute of Standards and Technology (NIST) on 23 July to 30 July 1996. The agenda for SIRREX-5 was established based on recommendations made in SIRREX-r. For the first time in a SIRREX activity, instrument intercomparisons were performed at field sites, which were near NIST. The goals of SIRREX-t were to continue the emphasis on training and the implementation of uniform measurement practices, investigate the calibration methods and measurement chains in use by the oceanographic community, provide opportunities for discussion, and intercompare selected instruments. As at SIRREX-4, the day was divided between morning lectures and afternoon laboratory exercises. A set of core laboratory sessions were concerned with 1) in-waterradiant flux measurements; 2) in-air radiant flux measurements; 3) measuring spectral radiance responsivity using the plaque method; 4)testing portable sources as calibration devices or stability monitors; and 5) various ancillary exercises designed to illustrate radiometric concepts. Before, during, and after SIRREX-5, NIST calibrated the SIRREX-5 participating radiometers for radiance and irradiance responsivity. The Facility for Automated Spectroradiometeric Calibrations (FASCAL) was scheduled for spectral irradiance calibrations for standard lamps during SIRREX-5 and three lamps form the SeaWiFS community were submitted and two were calibrated.
