Real Time Data

The NTAS site is WMO ID 48401, NDBC Partner Platform 41NT0.

A note on resolution, and one on ASIMet data formats.

Real time data is sent back to shore by several subsystems on the buoy. The buoy is equipped with two ASIMet loggers that transmit hourly averaged met data using the Iridium network. A subsurface telemetry system, consisting of an inductive modem transmitting via Iridium, sends back data from several instruments on the mooring line. Links to near-real-time data are on the right-hand column of this page.

NTAS data is also available from the OceanSITES THREDDS server at NDBC.


The twentieth NTAS buoy was deployed from the NOAA Ship FSV Pisces on November 12, 2021 at 18:57 UTC. It was recovered from the R/V Ron Brown on October 15, 2022 at 15:17 UTC.


Hourly meteorological data for the current deployment of the NTAS is received via the Iridium network. Data is displayed as a time series and is available for download as ASCII files as well as OceanSITES NetCDF files.
