Paper Abstract

The calibration of integrated water vapor amount retrieved from Cimel Sun radiometer, the main instrument of the worldwide Sun radiometer network AERONET ( is analyzed. The assessment procedure is based on the using of independent measurements derived from Global Positioning System (GPS) meteorology and parametric solar transmittance methods in solar 940 nm band. The results highlight the importance and the necessity of a continuous and flexible monitoring system for Sun radiometric retrieved water vapor. The established improved calibration procedure is useful in the framework of both water vapor spatial remote sensing calibration and validation activities, and climate applications for which this parameter remains a source of uncertainty.
