      abstract     = {The scale difference between point in situ soil moisture
                      measurements and low resolution satellite products limits
                      the quality of any validation efforts in heterogeneous
                      regions. Cosmic Ray Neutron Probes (CRNP) could be an option
                      to fill the scale gap between both systems, as they provide
                      area-average soil moisture within a 150–250 m radius
                      footprint. In this study, we evaluate differences and
                      similarities between CRNP observations, and surface soil
                      moisture products from the Advanced Microwave Scanning
                      Radiometer 2 (AMSR2), the METOP-A/B Advanced Scatterometer
                      (ASCAT), the Soil Moisture Active and Passive (SMAP), the
                      Soil Moisture and Ocean Salinity (SMOS), as well as
                      simulations from the Global Land Data Assimilation System
                      Version 2 (GLDAS2). Six CRNPs located on five continents
                      have been selected as test sites: the Rur catchment in
                      Germany, the COSMOS sites in Arizona and California (USA),
                      and Kenya, one CosmOz site in New South Wales (Australia),
                      and a site in Karnataka (India). Standard validation scores
                      as well as the Triple Collocation (TC) method identified
                      SMAP to provide a high accuracy soil moisture product with
                      low noise or uncertainties as compared to CRNPs. The
                      potential of CRNPs for satellite soil moisture validation
                      has been proven; however, biomass correction methods should
                      be implemented to improve its application in regions with
                      large vegetation dynamics},
