The validation of the sensor products, as well as a daily quality control, are required to get homogeneous and consistent temporal series (winds, waves and sea-ice). Inter-comparison with other sensors is necessary to fulfill this task. Thanks to the colocation system developped by the CERSAT, multi-sensors colocated datasets were generated to make easier intercomparison between various sensors and detection of possible sensor drifts. This section features :
- long term statistical analyses of the measurements from various sensors,
- comparisons and quality analyses of the data from various sensors,
- ongoing monitoring of various sensors.
Most of the features presented here take advantage of the CERSAT colocated datsets which enable easier inter-comparison of different sensors. This topic aims to be an overview of the various works performed at CERSAT on this topic.
