    String summary 
"Simple Ocean Data Assimilation (SODA) version 2.2.4 - A reanalysis of ocean 
climate. SODA uses the GFDL modular ocean model version 2.2. The model is 
forced by observed surface wind stresses from the COADS data set (from 1958 
to 1992) and from NCEP (after 1992). Note that the wind stresses were 
detrended before use due to inconsistencies with observed sea level pressure 
trends. The model is also constrained by constant assimilation of observed 
temperatures, salinities, and altimetry using an optimal data assimilation 
technique. The observed data comes from: 1) The World Ocean Atlas 1994 which 
contains ocean temperatures and salinities from mechanical 
bathythermographs, expendable bathythermographs and conductivity-temperature-
depth probes. 2) The expendable bathythermograph archive 3) The TOGA-TAO 
thermistor array 4) The Soviet SECTIONS tropical program 5) Satellite 
altimetry from Geosat, ERS/1 and TOPEX/Poseidon. 
We are now exploring an eddy-permitting reanalysis based on the Parallel 
Ocean Program POP-1.4 model with 40 levels in the vertical and a 0.4x0.25 
degree displaced pole grid (25 km resolution in the western North 
Atlantic).  The first version of this we will release is SODA1.2, a 
reanalysis driven by ERA-40 winds covering the period 1958-2001 (extended to 
the current year using available altimetry).";

Using griddap to Request Data and Graphs from Gridded Datasets

griddap lets you request a data subset, graph, or map from a gridded dataset (for example, sea surface temperature data from a satellite), via a specially formed URL. griddap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its projection constraints (external link).

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

griddap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/griddap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/griddap/jplMURSST41.htmlTable?analysed_sst[(2002-06-01T09:00:00Z)][(-89.99):1000:(89.99)][(-179.99):1000:(180.0)]
Thus, the query is often a data variable name (e.g., analysed_sst), followed by [(start):stride:(stop)] (or a shorter variation of that) for each of the variable's dimensions (for example, [time][latitude][longitude]).

For details, see the griddap Documentation.
