  abstract = {{T}wo electromagnetic models were used to simulate snow emission at {L}-band from in situ measurements of snow properties collected at {D}ome {C} in {A}ntarctica. {T}wo different approaches were used: one based on the radiative transfer theory and the other on the wave approach. {T}he soil moisture ocean salinity ({SMOS}) satellite observations performed at 1.4 {GH}z (21 cm) were used to check the validity of these models. {M}odel results based on the wave approach were in good agreement with {SMOS} observations, particularly for incidence angles lower than 55 degrees. {C}omparisons suggest that the wave approach is more suitable to simulate brightness temperature at {L}-band than the transfer radiative theory, because interference between the layers of the snowpack is better taken into account. {T}he model based on the wave approach was then used to investigate several {L}-band characteristics at {D}ome {C}. {T}he emission e-folding depth, i.e., 67% of the signal, was estimated at 250 m, and 99% of the signal emanated from the top 900 m. {L}-band brightness temperature is only slightly affected by seasonal variations in surface temperature, confirming the high temporal stability of snow emission at low frequency. {S}ensitivity tests showed that good knowledge of density variability in the snowpack is essential for accurate simulations in {L}-band.},
