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. Date-TimeDate-TimeIce Floeactual Cumulative FDDCumulative Freezing Degree MomentsCFDM 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 Floecalculated TairAir Temperaturedeg CCaptured by a meteorological sensor mounted on the scaffolding tower (Vaisala HMP45C).Ice Floeactual C-VVC-band NRCS in VV poldBNormalized Radar Cross Section (NRCS) values in VV polarization, captured at 25 incidence angle.Ice Floeactual C-HHC-band NRCS in HH poldBNormalized Radar Cross Section (NRCS) values in HH polarization, captured at 25 incidence angle.Ice Floeactual C-HVC-band NRCS in HV poldBNormalized Radar Cross Section (NRCS) values in cross polarization, captured at 25 incidence angle.Ice Floeactual ThicknessSea Ice ThicknesscmIn-situ measured sea ice thickness during physical sampling sessions.
