Adaptive observational network

From Glossary of Meteorology

adaptive observational network

An observational network in which the location and timing of measurements of atmospheric properties are changed on a daily basis in order to minimize some measure of forecast error.

To achieve this aim, atmospheric measurements must adapt to the flow observed on a particular day. For example, in midlatitude regions, enhanced atmospheric measurements in regions of large horizontal temperature gradients can lead to a significant reduction in forecast error. As these regions of strong baroclinicity move from one day to the next, the locations of enhanced measurements should also move.
