  abstract = {{T}he future {S}oil {M}oisture and {O}cean {S}alinity satellite time of overpass is 6 {A}.m. and 6 {P}.{M}. at the equator. {I}n many regions, morning dew is expected at the time of the satellite overpass and might play a role in soil moisture retrievals. {T}he aim of this study was to assess the effects of dew on {L}-band measurements. {R}adiometric, biomass, and dew measurements were performed over a natural grass field. {O}ur results show that at the diurnal scale, vegetation internal water content changes play a major role in emission. {A} direct impact of dew on measurements was not identified. {H}owever, a brightness temperature increase of 0.5 and 1 {K} was observed at vertical and horizontal polarizations' respectively. {T}his increase was detected later after dew, suggesting that it was not directly caused by the presence of dew on the grass blades. {O}ur hypothesis is that the observed increase in brightness temperatures is due to the absorption of dew water by the litter layer.},
