The document summarizes initial results from the SMOS satellite mission regarding spatial variations of L-band emissivity in Antarctica. Key findings include: 1) L-band brightness temperature is fairly constant in dry snow zones, suggesting potential to retrieve snow temperature from SMOS data in these areas. 2) Wet snow zones exhibit more temporal brightness temperature variations due to liquid water absorption and formation of icy layers during melt-refreeze cycles. 3) Radiative transfer modeling suggests snowpack density profiles are important for accurately modeling brightness temperature, particularly at horizontal polarization. Further data is needed to refine emissivity estimates and potential snow temperature retrievals from SMOS in dry snow zones.
