Variable description

ID 1 5 Integer System variable - Point identification number.
SLLONG 6 13 Real Data variable - longitude of the tide- gauge station used in determining the sea-level trends.
SLLAT 14 21 Real Data variable - latitude of the tide- gauge station used in determining the sea-level trends.
SLR 22 29 Real Data variable - relative sea-level trend calculated from tide-gauge station measurements; values are expressed in mm/year.
SLG 30 37 Real Data variable - long-term geologic trend. This variable is 0.0 for all stations with a relative sea-level trend value, and is included for compatibility within this series of NDPs.
SLC 38 45 Real Data variable - corrected sea-level trend. Since the geologic trend variable contains values of 0.0, this variable appears identical to the relative sea-level trend variable; and is included only for compatibility within this series of NDPs.
SLS 46 53 Real Data variable - local uplift or subsidence trend. Relative sea-level trend corrected for the global eustatic rate of sea-level rise (i.e., 1.5 mm/year).
SLYR 54 57 Integer Data variable - years of record of the tide gauge station used in determining the sea-level trends.

SLNAME 1 40 Char Data variable - name of the tide gauge used for determining the sea-level trends.
TRLONG 41 48 Real Data variable - longitude of a tide-gauge station used for determining the tide range variables.
TRLAT 49 56 Real Data variable - latitude of a tide-gauge station used for determining the tide range variables.
TRAVG 57 64 Real Data variable - difference between mean high water and mean low water for 1992; values in meters.
TRMAX 65 72 Real Data variable - maximum tide range, maximum measured range for the gauge station in 1992 (this value may be the "spring" or "diurnal" tide range, depending on geographic location); values in meters.
TRLVL 73 80 Real Data variable - mean tide level, a plane midway between mean low water and mean high water in 1992. Values are reckoned from the West Coast Mean Low Water Datum.

TRID 1 4 Integer Data variable - station number (used in the 1992 Tide Tables) of a tide-gauge station.
TRNAME 5 54 Char Data variable - name of a tide-gauge station (from the 1992 Tide Tables).
