Abstract:
Between August 1 and September 2, 2000, the Naval Postgraduate School Department of Oceanography's Radar And Drifter (RAD) Lab collected hourly averages of Codar measurements from three site around Monterey Bay. Surface currents for 328 grid points were computed. These currents are processed, interpolated data.
Purpose: These data were collected for oceanographic research.

Native_Data_Set_Environment:
Filenaming Convention: tuvs_MNTY_yr_mo_dy_hrmn tuv = total u/v current, ruv = radial u/v currents s = how radial data were produced (s = standard processing, nothing unusual was done in processing the back scatter energy spectra to create the radial vector data.) MNTY = Monterey Bay yr_mo_dy_hrmn = two digit year, month, day, hour, minute (GMT)

Data_Quality_Information:
Logical_Consistency_Report: N/A
Completeness_Report:
Data from August 18, 2000 hour 0200 is missing because two of the radars did not produce data at that hour. All data after September 24, 2000 are not included on the CD because data vectors are questionable.

Process_Step:
Process_Description:
Data from the instruments are called radial vecotors, or radial currents. Radial "vectors" represent current velocity directly toward or away from the radar. When one has radial current maps from more than one instrument at the same time, they can be combined to make total current vectors. These radial current vectors are organized in range rings, like rings around a bullseye. The radial currents are located every five degrees in an arc a fixed radius from the instrument. This comprises one range ring. There may be 20-30 of these range rings. The data on any range ring can be very gappy, so if the data gap as measured from the instrument is less than or equal to 20 degrees, radial vectors are linerally interpolated across the gap. The total current vectors are made. The "noInterp" files are the files with gaps, and the "RadInterp" files are the files after the linear interpolation has been done.

Summary of the radial to total procedure:

The way the total vectors are computed is that all the radials currents which meet specific temporal and spatial thresholds are included in the calculation.

The temporal criteria: only radials from the center (current) time are used. That is no radial data before or after the center time are included.

The spatial criteria: at the location of each total current grid point a 3 km circle is placed in the radial maps. Any radials from any of the sites that fall within that circle are included in the total calculation.

Thresholding criteria (pre-calculation): Any radial currents > 150 cm/s are discarded before the total calculation. A minimum of 3 radial from at least 2 sites are required, otherwise no calculation is performed.

The procedure is to place all the radial estimates that meet the above temporal, spatial, and thresholding criteria in a matrix, and use a linear least squares matrix calculation to determine the total u/v currents.

Thresholding criteria (post-calculation): Any total currents with a speed > 100 cm/s or associated mapping error > 1.2 are discarded.
