Representativeness of point soil moisture observations, upscaling and assimilation

abstract
To estimate the temporal evolution of the spatial mean soil moisture in the Optimizing Production Inputs for Economic and Environmental Enhancement (OPE3) field, the relationship between point measurements and the average behaviour of field-scale soil moisture has been investigated. In a simple variational assimilation experiment with the Community Land Model (CLM2.0), it has been shown that the soil moisture information from a representative site was much more appropriate for estimating the spatial mean soil moisture profile than the information from other sites. The best results for the re-analysis as well as for the prediction of the spatial mean soil moisture were obtained through the assimilation of observations from probes with time-mean differences between their recorded point values and the spatial mean values close to zero. Further improved results can be obtained by upscaling the point data, e.g. after matching the point observations cumulative density function to that of the spatial mean soil moisture.
