Based on the forward scatter visibility instrument working principle, the structural characteristics, operating environment, measurement error, causes for errors, and the error model of the forward scatter visibility instrument are analyzed. The factory calibration method, calibration parameters, and calibration parameters correction methods of the forward scatter visibility instrument are summed up, according to the needs of dissemination in the future, so to ensure the accuracy of visibility observation data. Based on the transmit parameter analysis of visibility values, the laboratory calibration method and calibration conditions of the forward scatter visibility instrument are put forwarded. The field optical device calibration, calibration plate, and manual calibration methods are discussed, to provide the references for the development of the future dissemination system and the establishment of the related calibration standards.
