Crowdsourcing as a possibility for obtaining atmospheric measurement data

The development of inexpensive sensors and the availability of masses of meteorological measurement data, mainly of air pressure, air temperature and air humidity, enable a spatial and temporal compression of conventional measurement networks. This opens up completely new possibilities not only for science but also for municipalities, companies and other institutions, e. g. in environmental monitoring and description of the local climate. The easy availability and operation of these sensors enable even the layman to operate them and to participate or even contribute to these measurement programs. This new way of collecting and incorporating measurement data outside the standard measurement networks is called crowdsourcing.The article serves the preparation of a corresponding VDI guideline and describes the available sensor technology, the assurance of data quality and the possibilities of data processing.
