Abstract

Calibration is required for most soil moisture sensors if accurate measurements are to be obtained. This can be time consuming and costly, especially if field calibration is undertaken, but can be facilitated by a good understanding of the behaviour of the particular sensor being calibrated. We develop generalized temperature correction and soil water calibration relationships for Campbell Scientific CS615 water‐content reflectometer sensors. The temperature correction is estimated as a function of the raw sensor measurement. The calibration relationship requires one soil‐related parameter to be set. These relationships facilitate field calibration of these sensors to acceptable accuracies with only a small number of samples. Copyright Β© 2005 John Wiley & Sons, Ltd.

## Abstract We present a new method for the assessment and calibration of medium‐range ensemble temperature forecasts. The method is based on maximizing the likelihood of a simple parametric model for the temperature distribution, and leads to some new insights into the predictability of uncertaint
