    String comment "GFDL experiment name = CM2.1U_Control-1860_D4. PCMDI experiment name = PIcntrl (run1). Initial conditions for this experiment were derived from a multi-step process. First, an atmosphere + land surface model was spun up with forcing agents at levels representative of the late 20th century. Second, the spun up atmosphere + land surface model was coupled to an ocean + sea ice model. Initial conditions for sea ice, ocean potential temperature and salinity were derived from late 20th century observations. Forcing agents consistent with year 1860 were applied to the coupled model which was integrated for a ~220 year adjustment period. Year 1 of the archived CM2.1U_Control-1860_D4 experiment data begins at the end of this adjustment period. CM2.1U_Control-1860_D4 forcing agents representative of conditions circa-1860 include the well-mixed greenhouse gases (CO2, CH4, N2O), tropospheric and stratospheric O3, tropospheric sulfates, black and organic carbon, dust, sea salt, solar irradiance, and the distribution of land cover types. The direct effect of tropospheric aerosols is calculated by the model, but not the indirect effects.";

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://upwell.pfeg.noaa.gov/erddap/griddap/datasetID.fileType{?query}
For example,
https://upwell.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.
