Deliverables and Good Practice Guides
SoMMet produced eight public Deliverables (D1 to D8), including three Good Practice Guides.
For easier navigation, the Deliverables are grouped below by overarching topic.
Traceability of point-scale soil moisture measurements
Deliverable D1 addresses metrological calibration and SI traceability for point-scale soil moisture measurements under laboratory conditions.
Full title of D1:
Report on the calibration of soil-moisture measurement devices using a primary method, based on evolved water vapour detection, and transfer standards, such as "standardised" loss on drying (LoD) or fibre-coupled spectrometers, to ensure SI-traceable point-scale soil moisture measurements with uncertainties of 5 % under laboratory conditions
DOI: 10.5281/zenodo.18788813
CRNS traceability, modelling and field calibration
Deliverable D2 focuses on the SI traceability and associated uncertainties of CRNS neutron response functions characterised in laboratory neutron fields.
Full title of D2:
Report on the traceability scheme and uncertainty model for validation of neutron response functions of CRNS neutron-measuring devices under laboratory conditions
DOI: 10.5281/zenodo.18798838
Deliverable D3 reports on the benchmarking and validation of neutron-transport models for interpreting CRNS signals under outdoor conditions.
Full title of D3:
Report on the comparison and validation of existing neutron transport models used to interpret CRNS signals measured under outdoor conditions
DOI 10.5281/zenodo.18803623
Deliverable D4 presents a good-practice guide to the field calibration of CRNS instruments for soil moisture retrieval.
Full title of D4:
Good practice guide for calibration practices for CRNS soil moisture data retrieval in outdoor field conditions covering on lateral scales ranging from 102 m to 103 m and to depths of up to 1 metre
DOI: 10.5281/zenodo.18804194
Comparison and harmonisation of soil moisture measurement methods
Deliverable D5 compares soil moisture measurement methods and examines their respective sensing domains.
Full title of D5:
Report on the comparison of soil moisture measurement methods and their different sensing domains (local and remote) including details on the constraints and accuracy of the methods and requirements for harmonisation
DOI: 10.5281/zenodo.18804770
Deliverable D6 presents a good-practice guide to harmonising soil moisture measurement methods.
Full title of D6:
Good practice guide for harmonising soil moisture measurement methods to overcome temporal and spatial differences (lateral scales ranging from point scale to km scale) and the influence of other state variables such as air humidity and soil temperature affecting the measurements
DOI: 10.5281/zenodo.18805234
Multi-scale soil moisture data fusion
Deliverable D7 reviews and compares approaches to combining soil moisture data across spatial and temporal scales.
Full title of D7:
Report on the comparison of the existing data fusion practices for soil moisture measurements on multiple lateral (from 10-1 m to 103 m and to depths of up to 1 metre) and temporal (from hours to days) scales to assess the soil moisture with traceable relative uncertainty of 20 % or better
DOI: 10.5281/zenodo.18806979
Deliverable D8 presents a good-practice guide to fusing soil moisture observations across spatial and temporal scales.
Full title of D8:
Good practice guide for interdisciplinary data fusion of soil moisture measurements on multiple scales
DOI: 10.5281/zenodo.18807290
