Resumen

A project to deploy GNSS-reflectometry equipment during the 1-year round MOSAiC campaign. The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition is a one-year-long expedition into the Central Arctic that took place from 10/2019 to 10/2020. For the first time, a modern research icebreaker operated in the direct vicinity of the North Pole year round, including the nearly half year long polar night during winter. MOSAiC represents the largest Arctic expedition in history. The campaign is led by AWI (Germany).
The German research vessel Polarstern travelled to the North Pole and got trapped in the sea ice on purpose, to drift during one year stuck to the sea ice floe.
This project is a contribution to the campaign, that includes the deployment of a set of GNSS-Reflectometry (GNSS-R) equipment on the drifting sea ice floe during one year, and later on process and analyze the acquired data. The reflected signals will be inverted into several geophysical parameters of the sea ice and snow cover.

Actividades del proyecto

To prepare the equipment for one year of nearly autonomous operations in the Arctic environment. To assist the operators in case of problems during the 1 year measurements. To recover the data and process them. To develop the retrieval algorithms for sea ice altimetry, snow cover thickness, sea ice thickness, and potential for snow and ice permittivities and roughness.
