PROJECT BACKGROUNDStarting from the experience achieved during the previous JRP ENV07 MeteoMet on the traceability to SI of some Essential Climate Variables (ECVs) and the evaluation of calibration uncertainties, this joint research project, JRP (ENV58 MeteoMet2) aims to extend the investigations to other variables and at evaluating further aspects and contributions to the uncertainty.
NEED FOR THE PROJECTAs stated by GCOS “Long-term, high-quality and uninterrupted observations of the atmosphere, land and ocean are vital for all countries, as their economies and societies become increasingly affected by climate variability and change”. High-quality observations are possible only if they are based on a sustained traceability to SI and with uncertainties associated to the measured ECVs.
SCIENTIFIC AND TECHNICAL OBJECTIVESTo investigate the performance of humidity sensors in real working conditions, reference systems will be developed to validate reference instruments and test facilities for radiosonde and airborne sensors. Two types of sensors for fast changing ECVs will be improved: a microwave hygrometer, and a reference free space instrument for temperature and humidity detection.
EXPECTED RESULTSThe project will deliver advances to an international science area of critical importance to future global sustainability. The dissemination and impact will be based on the network of collaborators, established during the previous JRP ENV07 MeteoMet. The vision of this JRP is to establish a permanent collaboration between metrology and meteorology communities, for the benefit of the future generations of climatologists.
MeteoMet aims to develop metrological traceability for the measurement of main essential climate variables (ECV) defined by GCOS.
It is structured in 3 technical work packages (WP), each covering a different area of observation, the Impact WP and Managment WP.
