The UPI Project August–September 1981

The UPI project was sponsored by the United States Department of Energy Contract DE-AT06-76-EV-71025 to Drs. B. Hickey & J. Dungan Smith at the University of Washington.

The University of Washington maintained 7 current meter moorings, UPI-1, UPI-1 surface (UPI-1S), UPI-2, UPI-3, UPI-3 surface (UPI-3S), UPI-4, UPI-5, from Aug. 18, 1981 through Sept. 5, 1981 off the Washington coast. Current meters were a mix of Aanderaa (AA) and Vector Measuring Current Meters (VMCM) instruments. The AA data was sampled in 10 minute intervals. The VMCM data was sampled in 4 minute intervals. The u, v time series data were then edited for spurious values, filtered with a half power point of about 2.5 hours and in some cases interpolated to even hours to produce the hourly data available below. Temperature time series, when available, were edited for spurious values, and left as 10 minute samples.

Abbreviations and units are:
Depth, m, meters,
Speed, spd, cm/sec,
Direction, D, degrees, true north,
u component (eastward), u, v component (northward), v, cm/sec, true North,
Temperature, T, ºC,
Pressure, P, decibars,
Date and time is listed as DATE. Add 8 hours to convert to GMT. Format mm/dd/yy hh:mm.

Data files consist of ASCII tab delimited files, one per meter. Headers indicate the mooring, the variable, and depth rounded to the nearest meter. For example UP3Su5 indicates the data is from the UP3 surface mooring, u component at 5m, UP5v32 indicates the data is from the UP5 mooring, v component, at 32m. The last column, JJ, is zero filled to indicate last data column for that meter.
