During the last years, the worldwide interaction between the Metrology and Meteorology communities has improved and increased. The EURAMET, the European association of national Institutes of Metrology, is presently funding several projects aiming at delivering results of valuable impact for the meteorology and climatology sciences. The key aspect of these projects is to establish traceability of measurements and uncertainties of measured physical and chemical quantities and Essential Climate Variables.
The session on Metrology for Meteorology and Climate is organized to give an opportunity to present and discuss needs, methods, expertise and devices with objective to cooperate in producing more reliable data. It will be an occasion to reciprocally increase knowledge and understanding for these two fields, semantically so similar but each one representing problems of different nature.
A special focus on climate reference stations and networks will be included.
Topics for the session are
• Traceability and uncertainty in weather observations.
• Metrology applied to Ground based systems. Temperature, humidity and pressure sensors. Wind speed and direction, solar radiation.
• Requirements and instrumental features of climate reference stations
• Quantities of influence and mutual influences. Sensors dynamics.
• Special calibration procedures for upper air measurements and aircraft-based measurements.
• Ocean research: metrological traceability to the SI system for the measurement of the key variables salinity, pH, composition and dissolved oxygen content of sea water.
• Water: water vapour, liquid water, ice, hygrometry, soil moisture.
• Calibration and traceability for rain and snow gauges.
• Permafrost temperature measurements: instruments, procedures and calibrations.
• Assessment of the historical temperature measurement data with respect to uncertainties on instruments used.
• Thermal metrology for meteorology and climate.
• Chemical metrology for environment and climate.
• Instruments and measurements capabilities, calibration procedures, best practice and regulations.
