Rain on snow (ROS) understudied in sea ice remote sensing: a multi-sensor analysis of ROS during MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate)

Julienne Stroeve et al.

Data sets

Surface-based Ku- and Ka-band polarimetric radar for sea ice studies ( J. Stroeve, V. Nandan, R. Willatt, R. Tonboe, S. Hendricks, R. Ricker, J. Mead, R. Mallett, M. Huntemann, P. Itkin, M. Schneebeli, D. Krampe, G. Spreen, J. Wilkinson, I. Matero, M. Hoppmann, and M. Tsamados

Short summary
Impacts of rain on snow (ROS) on satellite-retrieved sea ice variables remain to be fully understood. This study evaluates the impacts of ROS over sea ice on active and passive microwave data collected during the 2019–20 MOSAiC expedition. Rainfall and subsequent refreezing of the snowpack significantly altered emitted and backscattered radar energy, laying important groundwork for understanding their impacts on operational satellite retrievals of various sea ice geophysical variables.
