Video S1 shows a conjugate radar-GNSS event that took place on 17 July 2023, with geospatial locations (left), spectral density (top right), and timeseries information (bottom right).

Video S2 shows the ICEBEAR echo clustering analysis, for the same 17 July 2023 event, showing dbscan-identified clusters in 6-second bins on the left side and their spectral density on the right side.

Video S3 shows a close-up of the radar tracking motions observed by ICEBEAR during the 17 July 2023 event, posting the velocities of each tracked cluster.

Video S4 shows shows the ICEBEAR echo clustering analysis, for the 2 August 2023 multi-instrument conjunction, showing dbscan-identified clusters in 6-second bins on the left side and their spectral density on the right side.
