1. The CIMO LC-PrIn maintains
   • capability to perform dynamic calibration, metrological confirmation and intercomparison of rain intensity gauges in the laboratory
   • suitable equipment for
     - laboratory calibration
     - the traceability of its measurement standards and
     - measuring instruments,
     therefore providing support for certification of the instruments’ performance as a suitable Independent Third Party Organisation.
   • a set of gauges acting as a working reference for field measurements of rainfall/snow intensity.
2. The CIMO LC-PrIn conducts research on
   • suitable equipment and procedures for routine field testing of network precipitation gauges which would be recommended for the standardization of field calibrations of precipitation gauges during operational use,
   • suitable devices and technical procedures to improve the testing capabilities following the results of the WMO Field Intercomparison of RI gauges
   • the interpretation of the influence of measurement errors on meteo-hydrological applications
   • correction procedure for historic data series
   • post-processing techniques for automatic correction of the measured rain intensity.
3. The CIMO LC-PrIn has the necessary testbed and equipped facility to perform regular field measurement campaigns or international/regional comparisons with the purpose to test
   
   • the performance of different measuring principles for rainfall intensity (RI) and
   • the effects of laboratory calibrations mentioned above on the measured intensities.
4. The CIMO LC-PrIn collaborates and cooperate with
   • relevant CIMO Expert Teams in developing guidance material
   • WMO regional instrument centres (RICs) and other international testbeds for the organization and participation in field tests for specific purposes or in international/regional intercomparisons;
5. The CIMO LC-PrIn proposes:
   • standards on precipitation intensity measurements for consideration in WMO and ISO technical committees
   • reports on all significant tests to the CIMO community, through publication of IOM reports and publications in scientific journals
   • technical support and vocational training and periodic training courses on general and specific issues related to liquid/solid rainfall intensity measurements.
