The China Meteorological Administration (CMA), on 15 November, inaugurated the WMO Measurement Lead Centre for Ground-Based Integrated Meteorological Observation in Changsha, China (MLC Changsha). The ceremony highlighted the Centre’s capabilities and significance for the testing of measurement instruments and observing systems.

Measurement Lead Centres (MLCs) are designated by the Commission for Observation, Infrastructure and Information Systems (INFCOM) to provide high-level expertise in the testing of surface-based remote-sensing and in situ instruments as well as in the standardization of instrument performance. Currently, 13 MLCs worldwide conduct research and testing of instruments in several application areas of measurements. Through their experimental work and contributions to WMO guidance material, MLCs help WMO Members better understand the capabilities and limitations of emerging technologies and their suitability for operational use.

MLC Changsha has exceptional capacity for testing a range of in situ and surface-based remote-sensing instruments, with specialist capabilities in testing and calibration of weather radars. In addition to instrument evaluation, the Centre will play a key role in providing guidance and training to WMO Members on the use, testing and calibration of weather radars and other instruments hosted at the facility.
