Abstract:
This data set is part of the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition in the north pole. The observations were taken in the MOSAiC Remote Sensing site, during the second Leg (December 2019 - January 2020). The instrument is placed over an Ice floe, and the floe drifts for the entire stated period, therefore the geographical position is the actual position of the same drifting ice floe.
The instrument constis on a GNSS reflectometer, collecting a combination of direct and reflected signals with an up-looking and a down-looking antenna with different polarizaitons (RHCP for the up-looking and LHCP for the down-looking antenna). The antennas are mounted on top a tripod, separated from the ground 1.86 m. and 0.64 m. respectivelly. In addition, the uplooking antenna is pointing towards the zenith, and the down-looking antenna is tilted 45º with respect to nadir (i.e. in the middle between horizon and nadir). The set of measurements are time and geo-located. Each measurement contains the transmitting satellite information, the azimuth, and elevation angle of the transmitting S/C, and the peak power of both the direct and reflected waveforms. The instrument sampling rate is 10 seconds for both channels.
The purpose of the instrument is to validate the sea-ice layer model used in GNSS-R and L-band radiometry instruments.
