  abstract = {{T}his paper focuses on the sensitivity of {L}-band multi-parameter retrievals across the range of angular measurements available from the {SMOS} ({S}oil {M}oisture and {O}cean {S}alinity) mission. {T}he {SMOS} core algorithm was used to evaluate two-parameter retrieval scenarios including soil moisture and one of either i) vegetation water content, ii) surface roughness, iii) vegetation temperature, or iv) surface soil temperature. {F}or all pairs a range of parameter value combinations were compiled to run the model in forward mode. {S}ubsequently, the resulting angular brightness temperature simulations with two unknown parameters were compared against the brightness temperature response derived from reference simulations using data from the {N}ational {A}irborne {F}ield {E}xperiment 2005 ({NAFE}'05) in {A}ustralia. {T}his paper showed that the two-parameter retrieval accuracy of soil moisture is strongly affected by the surface moisture conditions, the polarization of the brightness temperature data, and the choice of the secondary ancillary parameter to be retrieved. {T}he synthetic analysis demonstrated a tendency for better retrievals from dual-polarized data at large incidence angles (40-50 degrees). {V}alidation with airborne brightness temperature observations at {L}-band did not demonstrate such a strong angular dependency, although it confirmed that the simultaneous retrieval of soil moisture and vegetation properties is not preferable as opposed to i) soil moisture and surface roughness or ii) soil moisture and surface soil temperature, especially under dry moisture conditions.},
