The climatology is presented as a spatial field from -50--99 lon and 16-52 lat for each year day (1-365). Means were calculated on log transformed data and then unlogged to return to original engineering units. This was done to satisfy the assumption of normality when computing a mean. This procedure was not done for SST and RRS products, which typically do not have a log-normal distribution. Also, a \"count\" field is included for each mean field. The count field indicates how many 1 day averages from 2003-01-01 through 2017-12-31 were used to create the mean field. This corresponds to how many years between 2003-01-01 through 2017-12-31 had a measurement available to average";

String summary "1-Day Climatology is the average of the record of MODIS Aqua 1-Day 1 km Composite by day from 2003-2017. Daily climatology includes counts of observations per 1 km pixel. Because optical products are not normally distributed, they were first Log10 transformed, then averaged, then back transformed to represent the mean. Ocean color and sst calculation by SeaDas; Regridded to Mercator lon/lat projection. Processed at the University of Delaware. Computed for the Mid-Atlantic Regional Association Coastal Ocean Observing System.";

Data Access Protocol (DAP) and its
projection constraints.
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.
