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).
- If targeting a specific drifter, use its WMO number to generate a graph from the OSMC web site. See instructions.
- To graph all drifters within a particular region, on the OSMC web page, follow these instructions.
- You can also visualize drifter data, altimetry, sea surface temperatures, and other GTS real time data from the last 10 days at AOML's CoastWatch/OceanWatch web page. See instructions.
- 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.
