SoMMet (Soil Moisture Metrology)
Project description:
SoMMet (Soil Moisture Metrology) is a a Joint Research Project within the Programme 'European Partnership on Metrology' of EURAMET. The time frame is October 2022 – September 2025 (duration of 36 months). The SoMMet Consortium brings together a diverse team of scientists from 18 institutions placed all over Europe.
The overall aim of SoMMet is to develop novel and traceable methods and establish a metrological infrastructure for soil moisture measurements covering lateral scales ranging from the decimetre to kilometre.
The project focuses on creating a metrological framework to achieve SI-tracable soil moisture measurements with an uncertainty of 5% under laboratory conditions. In the domain of CRNS methodology, it aims to develop new validation practices for outdoor conditions, including standardisation of CRNS on-field calibration procedures and neutron transport modeling. Additionally, SoMMet investigates the constraints and accuracy of soil moisture measurement methodologies using intercomparison campaigns on local and remote sensing. The overarching objective is to achieve a traceable relative uncertainty of 20% or better, harmonizing diverse data like point-scale sensors, satellite measurements, CRNS and modeling.
The project 21GRD08 SoMMet has received funding from the European Partnership on Metrology, co-financed from the European Union's Horizon Europe Research and Innovation Programme and by the Participating States.
