1	The exact column name as it appeared in the raw file before any cleaning.	A common or understandable name for the variable.	The physical units associated with the variable (e.g., m, PSU, °C).	The description supplied by the original data provider explaining what the variable represents.	The medium from which the measurement was taken (e.g., water, air, sediment). Extracted from the header or assigned manually.	Whether the value is a direct measurement or a calculated value.
2	Date-Time	Date-Time			Ice Floe	actual
3	Cumulative FDD	Cumulative Freezing Degree Moments		CFDM represents the cumulative sum of the air temperature differences below freezing point, calculated at more frequent intervals (here, every 5 min) rather than daily.	Ice Floe	calculated
4	Tair	Air Temperature	deg C	Captured by a meteorological sensor mounted on the scaffolding  tower (Vaisala HMP45C).	Ice Floe	actual
5	C-VV	C-band NRCS in VV pol	dB	Normalized Radar Cross Section (NRCS) values in VV polarization, captured at 25 incidence angle.	Ice Floe	actual
6	C-HH	C-band NRCS in HH pol	dB	Normalized Radar Cross Section (NRCS) values in HH polarization, captured at 25 incidence angle.	Ice Floe	actual
7	C-HV	C-band NRCS in HV pol	dB	Normalized Radar Cross Section (NRCS) values in cross polarization, captured at 25 incidence angle.	Ice Floe	actual
8	Thickness	Sea Ice Thickness	cm	In-situ measured sea ice thickness during physical sampling sessions. Interpolation has been made between sessions.	Ice Floe	actual
