MetEOC3 project (2017-2020)

European Metrology Programme for Innovation and Research (EMPIR) project MetEOC3 - "Metrology for Earth Observation and Climate".

The overall aim of the project is to contribute to the establishment of the necessary metrology infrastructure, tailored to climate needs in readiness for its use in climate observing systems. This project is the follow-up of the EMRP MetEOC2 where Metrology Research Institute is contributing to collection of set of empirical data to support the building of bidirectional reflectance distribution function (BRDF) models needed to utilise test sites for other than nadir observations and, in particular, for non-instrumented PICS as calibrations test sites.

Collection of empirical data for BRDF models

Metrology Research Institute will measure BRDF of sand samples from the visible (VIS) to infrared (IR) wavelength range (400 to 1650 nm). For this purpose a new gonioreflectometer is being developed, capable of measuring horizontally aligned samples. Sand will be brought from the test sites in the Sahara desert by partners from National Physics Laboratory (UK).
