                      practice guidelines for the validation of global
                      coarse-scale satellite soil moisture products. We provide
                      theoretical background, a review of state-of-the-art
                      methodologies for estimating errors in soil moisture data
                      sets, practical recommendations on data pre-processing and
                      presentation of statistical results, and a recommended
                      validation protocol that is supplemented with an example
                      validation exercise focused on microwave-based surface soil
                      moisture products. We conclude by identifying research gaps
                      that should be addressed in the near future.},
