“…In these regions of low T B at 18 and 36 GHz, the microwave signal is likely scattered, within the snow pack (volume scattering due to the formation of depth hoar for instance), at the snow surface and snow/sea ice interface (scattering over rough surfaces), and possibly within the sea ice (volume scattering in the desanilized multi‐year sea ice). The microwave scattering signatures have been analyzed recently, using a state‐of‐the‐art radiative transfer model to explore the co‐variability of the microwave observations (passive and active) (Soriot et al., 2022). This study underlined the complexity of the scattering responses, and the difficulty to propose consistent and quantified explanations for all signatures, across frequencies.…”

“…A database with observations at CIMR frequencies is built, merging the SMAP observations at 1.4 GHz and the AMSR2 ones at 6, 10, 18, and 36 GHz, to characterize sea ice and snow (Soriot et al., 2022). The statistical analysis between the PMW measurements and the SIT estimates are conducted for the ICESat‐2 SIT (Petty et al., 2022), for the CS2SMOS SIT (Ricker et al., 2017), and for Nucleus for European Modelling of the Ocean (NEMO) (Madec & Team, 2008; Rousset et al., 2015) modeled SIT.…”

“…A full description of the model can be found in Picard et al (2018). The model also allows for the inclusion of freshwater and saline ice layers that can be combined with snowpacks to properly represent observed conditions (Soriot et al, 2022;Murfitt et al, 2022Murfitt et al, , 2023.…”
