WMO-IOC Regional Marine Instrument Centres (RMICs) have been established by JCOMM (Recommendation 1, JCOMM-III) as a mean to provide (i) facilities for the calibration and maintenance of marine instruments and the monitoring of instrument performance; (ii) assistance with regard to instrument inter-comparisons; and (ii) appropriate training facilities. The goal of RMICs is to facilitate adherence of observational data and metadata and processed observational products to higher level standards for instruments and methods of observation. The second JCOMM Marine Instrumentation workshop will be held at the RMIC for the Asia-Pacific region. The workshop is expected to help developing capacities of countries from the region involved in the making of marine meteorological and other appropriate oceanographic observations. One can expect that such activities would eventually improve quality, consistency, traceability of the observations made available to end users in the region, including National Meteorological and Hydrological Services (NMHSs); hence improving final products and services delivered by all in the region.
