Data Telemetry

TAO System Data from the array are telemetered in near-real-time via
Service Argos utilizing the NOAA polar-orbiting satellites. The buoy data are processed daily, calibration coefficients and quality controls are applied, and the data are made available to the international scientific community and to the public in general.

TAO has encouraged scientific utilization of the moored measurements by developing sophisticated data management and dissemination sources. These include distribution of TAO data and analyses through the World Wide Web and an Internet anonymous-ftp data base.

ATLAS moorings transmit daily mean values from the previous day and the most recent hourly surface meteorological observations. In order to reduce battery requirements and Service Argos charges, ATLAS moorings transmit for 8 hours per day, from 0600-1000 and 1200-1600 local time. Across the Pacific array this results in very few observations reported in real-time between 0600 and 1200 UTC.

Real-time updates of daily mean data are made to the TAO web pages on a daily basis. In addition, daily mean ocean temperature and up to 4 hourly surface wind, relative humidity and air temperature observations are submitted onto the Global Telecommunications System (GTS) by Service Argos, primarily for use by operational data centers around the world. Complete high temporal resolution data (hourly in traditional ATLAS systems, 10-minute or 2-minute in newer systems) are available in delayed mode from the TAO data delivery page after recovery of the moorings.

Data are also available from the National Oceanographic Data Center in Washington DC, and the National Climatic Data Center in Asheville, North Carolina.
