GCOOS Data Portal: Advance Data Access

Data Call Interactive

The following is a form to interactively retrieve data using a form (see the tab on Direct Call Instructions for more on this). To retrieve data, simply provide the inputs and click on the [Retrieve Data] button to generate the CSV file.

Data Call Instructions

The following is the syntax for direct data retrieval from GCOOS repository.

Syntax:

http://gcoos.rsmas.miami.edu/dp/get_data.php?bbox={1}&start={2}&stop={3}&obs={4}&fmt={5}&sortBy={6}

where:

{1} westlon,southlat,eastlon,northlat, where:

• westlon = longitude of western edge of bounding box expressed as a floating point number
• southlat = latitude of southern edge of bounding box expressed as a floating point number
• eastlon = longitude of eastern edge of bounding box expressed as a floating point number
• norhtlat = latitude of northern edge of bounding box expressed as a floating point number

{2} start date beginning at 00:00:00 UTC formatted as yyyymmdd

{3} stop date ending at 23:59:59 UTC formatted as yyyymmdd

{4} observation to retrieve

• current: for the ocean current data (speed, direction, meridional and zonal velocities)
• water_temperature: for water temperature data
• salinity: for salintity measurements
• winds: for winds (speed, direction and gust)
• air_pressure: for barometric readings
• air_temperature: for air temperature readings
• dew_point: for dew point measurements
• sea_surface_elevation: water level/height/tide readings
• do: for dissolved oxygens (various water depths and bottom)
• solar: solar radiations
• water_level: water level measurements

{5} desired output format. Only csv is currently supported.

{6} ascending sort order:

dates: sort the output by dates;
provider: sorth the ouput by data provider, then dates; or
station: sort the outp by the name of the station.

Example:

To access the water temperature data in the repository for all the Gulf region for the period November 01, 2008 (time: 00:00:00 UTC) to November 15, 2008 (23:59:59 UTC) and sorted by dates, the call should be: http://gcoos.rsmas.miami.edu/dp/get_gcoos_data3.php?bbox=-98.4,21.7,-80.5,31.0&start=20081101&stop=20081115&obs=water_temperature&fmt=csv&sortBy=dates

SOS Implementation

NOTICE! No changes to namespace (URNs) for platforms and sensors will be implemented to this portal while the issue is still being discussed in the community. Changes to the syntactic architecture of the URN will be announced before the implementation.

This SOS Server (http://gcoos.rsmas.miami.edu/dp/sos_server.php) implements the IOOS DIF Schema ver. 0.6.1. Please note the following syntax and parameters for direct access:

Majority of the GCOOS local data nodes (LDN) have implemented their independent SOS servers. The following is a directory for the SOS implementations and links to schema used. A link is also available to read latest data. The module reads the results of the "GetCapabilities" and list all offerings and requirements and from there, using the "GetObservation" functionality, reads the latest data.
