163,In relation to local coordinate axes at a (grid) cell edge.
164,"When using entry 10, the lower limit is used to encode the quantile q (must be an integer between 0 and Q) while the upper limit is used to encode the total number of quantiles Q. This defines the probability of the parameter falling within quantile q. For instance, to encode the probability of falling within the 10th percentile, then q=10 and Q=100; to encode the probability of falling within the 1st tercile, then q=1 and Q=3."

287b,"'Undetected' means that the received radar signal is at or below noise level."
287c,"‘No data’ describes that a data point is out of range or in a blanked sector."
287d,"‘Implausible data / outliers’ refers to values that are not physically plausible."
283a,"BFI2D is calculated by dividing the BFI by an expression that increases with the directional spread and decreases with the peakedness. It comes from the consideration that an increase of the directional spread reduces the excess of kurtosis, which is not taken into account in the BFI alone. Mori, N., M. Onorato, and P. A. E. M. Janssen, 2011: On the Estimation of the Kurtosis in Directional Sea States for Freak Wave Forecasting. J. Phys. Oceanogr., 41, 1484–1497, https://doi.org/10.1175/2011JPO4542.1"
283b,"Crest-trough correlation is an estimate of the auto-correlation between the crest heights and the trough depths. In narrow-banded seas this parameter is quite high, because crests and troughs are approximately the same size. Gemmrich, J., Cicon, L. Generation mechanism and prediction of an observed extreme rogue wave. Sci Rep 12, 1718 (2022). https://doi.org/10.1038/s41598-022-05671-4"
283c,"This is a metric that quantifies the wave-induced mechanical fatigue on the sea-ice pack (0 means broken, 1 means solid). This metric only makes sense in the presence of sea ice."
