"This is based on the JPL daily MUR SST v4.1 Climatology (2003-2014) downloaded from ftp://mariana.jpl.nasa.gov/mur_sst/tmchin/seasonal/ .
The anomaly is created from the climatology and SST data which is downloaded daily from ftp://podaac-ftp.jpl.nasa.gov/allData/ghrsst/data/GDS2/L4/GLOB/JPL/MUR/v4.1/ to NOAA NMFS SWFSC ERD by erd.data@noaa.gov . For leap years, the day 365 climatology was used for day 366.
The data for the most recent 4 days is usually revised everyday. The data for other days is sometimes revised.

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.

(easy) You can get data by using the dataset's Data Access Form. It makes the URL for you.
(easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
(not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by hand or with a computer program or script.

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.
