It was produced with a modified version of the Weather Research and Forecasting (WRF) model, Polar WRF or PWRF (v3.6.1), which optimizes the surface energy budget and parameterization of sea-ice and permanent ice surfaces. The modifications included implementation of a variable sea-ice and snow thickness and seasonally-variable sea-ice albedo. The WRF model was run with Four Dimensional Data Assimilation (FDDA), a combination of analysis and observation nudging. The model outputs represent hourly results at ~12 km spatial resolution with the goal to provide the meteorological dataset needed for air quality (AQ) modeling in the Arctic.

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.
