Abstract
A method for estimating surface moisture content of wood chips for use in a pulp and paper production process comprises measuring chip surface moisture using an infrared surface moisture sensor, and adjusting a calibration of the surface moisture measured with a model using values of a set of optical parameters representing light reflection characteristics of the wood chips, to estimate their surface moisture content.
