Instructions for use of the DART data access pages
NDBC maintains an archive of DART data going back to January 1, 2003. This archive is available via the NDBC web site (http://www.ndbc.noaa.gov/). This document describes the use of two dynamic web pages that have been created to make these data more easily accessible to the (Short-term Inundation Forecasting for Tsunamis) SIFT program (or any program).
DART Station List
The DART Station List returns a plain text listing of DART stations on the NDBC web site. The page can be found at http://www.ndbc.noaa.gov/dart_stations.php. There are no arguments required for this URL. The output includes the station ID, location, latitude, longitude, water depth, deployment start date/time and threshold of all DART stations on the NDBC web site. Here is a sample format:

Negative latitudes represent the southern hemisphere. Negative longitudes represent the western hemisphere.
You can retrieve and display a plain text listing of NDBC's historical DART data that matches the station ID, starting date, and ending date that you specify. Specify these by modifying the arguments in this URL - http://www.ndbc.noaa.gov/dart_data.php?station=46401&startmonth=&startday=&startyear=&endmonth=&endday=&endyear=. The arguments for the station ID and starting and ending dates are specified as follows:
These arguments may be entered in any order, but all must be given valid values.
For example; to retrieve data from station 46401 for January 4, 2004 through January 10, 2004; use the following URL:
This will return all water column heights on the NDBC web site for station 46401 from 00:00:00 UTC on January 4, 2004 through 23:59:59 UTC on January 10, 2004, inclusive. The output will display the parameters followed by the data. The data includes:
