  abstract = {{T}his paper presents a comparison and an evaluation of five soil moisture products based on satellite-based passive and active microwave measurements. {P}roducts are evaluated for 2005-2006 against ground measurements obtained from the soil moisture network deployed in {M}ali ({S}ahel) in the framework of the {A}frican {M}onsoon {M}ultidisciplinary {A}nalysis project. {I}t is shown that the accuracy of the soil moisture products is sensitive to the retrieval approach as well as to the sensor type (active or passive) and to the signal frequency (from 5.6 {GH}z to 18.8 {GH}z). {T}he spatial patterns of surface soil moisture are compared between the different products at meso-scale (14.5 degrees {N}-17.5 degrees {N} and 2 degrees {W}-1 degrees {W}). {A} general good consistency between the different satellite soil moisture products is shown in terms of meso-scale spatial distribution, in particular after convective rainfall occurrences. {C}omparison to ground measurement shows that although soil moisture products obtained from satellite generally over-estimate soil moisture values during the dry season, most of them capture soil moisture temporal variations in good agreement with ground station measurements.},
