Real Time Graphs and Data

Real time drifter data and graphs are distributed on the Global Telecommunication System (GTS) for improved weather and climate forecasting and ocean state estimation. On this page, we provide instructions on how to obtain these GTS data streams using NOAA's Observing System Monitoring Center.

To make a graph or get data from a particular drifter, you will need its World Meteorological Organization (WMO) identification number, which is different from the ID used in our quality-controlled data base (see a WMO/ID cross reference file if you don't know the WMO number already).

Download Data

  • With a single click, you can download data from all drifters for the past 90 days from the OSMC ERDDAP server. The parameters have been pre-selected. These data is in comma-separated-value (CSV) format. See more information about this file.
  • To obtain data from all drifters in formats such as ASCII, NetCDF or Matlab, follow these basic instructions and download from the OSMC ERDDAP server.
  • For more advanced queries, like getting data in a desired format from a specific drifter or a batch of drifters spanning a particular time period and/or region, follow these advanced instructions and enter the parameters of interest at the OSMC ERDDAP server.
