ADCP MOORING DATA

K. Kutsuwada (Tokai U., Japan)

Announced availability: 1 October 1994

Data Access

Japanese Acoustic Doppler Current Profiler (ADCP) mooring velocity data are available via anonymous FTP from the Japanese TOGA COARE FTP site at the University of Tokyo (ftp://ftp.ccsr/u-tokyo.ac.jp) in subdirectory pub/TOGA/ADCP, filename adcp_tokai.tar. Data are also available from the COARE Moored Data Archive at NOAA/PMEL's Tropical Atmosphere-Ocean Array (TAO) Project Office, (http://www.pmel.noaa.gov/coare/coare-data.html), along with other COARE mooring data.

The original data have also been archived at NOAA's National Oceanographic Data Center (NODC) in Silver Spring, Maryland (http://www.nodc.noaa.gov), the repository for COARE oceanographic data, and at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado (http://dss.ucar.edu/pub/toga_coare/), the site of the TOGA COARE deep archive.

Background

Four ADCP moorings (0, 147E; 0, 154E; 2N, 156E; and 2S, 156E) were operated by Japan's Tokai University during TOGA COARE. The moorings were equipped with 150 kHz ADCPs (at 300 m, sampling every 15 seconds, 20-minute averages).

Data File Information

Number of data directories: 2 (u_vel_Z, v_vel_Z)
Number of data files: 6 per directory 
uday147e   1/1/92 - 2/23/93; 0  147E; 50m - 230m (10m intervals)
uday154e   3/1/92 - 2/15/93; 0  154E; 20m - 240m (10m intervals)
uh00147e  11/7/92 - 2/24/93; 0  147E; 30m - 230m (10m intervals)
uh00154e  11/6/92 - 2/16/93; 0  154E; 20m - 240m (10m intervals)
uh2n156e  11/6/92 - 2/15/93; 2N 156E; 20m - 160m (10m intervals)
uh2s156e  11/6/92 - 2/17/93; 2S 156E; 30m - 210m (10m intervals)
Each filename is based on current component (u or v), time interval (daily->day, hourly->h), longitude (daily data) and longitude and latitude (hourly data). For example "uday147e" means a file of daily data of the zonal current at 0, 147E; "vh2s156e" means a file of hourly data of the meridional current at 2S, 156E.

In the first line of each file, year/month/day(/time) for the first and the last records and record length are indicated. In the second line, current depths are indicated.
Unit: cm/s for all data; Positive values denote eastward or northward current components.
Depth interval: 10 m
Time interval: hourly or daily

Dataset format: ASCII
Dataset volume: 789,201 bytes
