Deliverable 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

Key Points

The aim is to compare different data fusion practices for accurate soil moisture measurement across various scales.
Comparison of existing data fusion techniques
Assessment of lateral scales from 10^-1 m to 10^3 m
Evaluation of temporal scales from hours to days
Focus on achieving relative uncertainty of 20% or better
Identification of effective data fusion methods
Demonstration of varying effectiveness across temporal and lateral scales
Highlighted importance of relative uncertainty in soil moisture assessments
