Abstract:
... The contrast between the point-scale nature of current ground-based soil moisture instrumentation and the ground resolution (typically >10^2 km^2) of satellites used to retrieve soil moisture poses a significant challenge for the validation of data products from current and upcoming soil moisture satellite missions. Given typical levels of observed spatial variability in soil moisture fields, this ...
