    String history 
"This is based on the JPL monthly MUR SST v4.1 daily climatology (2003-2014) downloaded from ftp://mariana.jpl.nasa.gov/mur_sst/tmchin/seasonal/ .
The daily 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.
This monthly anomaly is a simple mean of the daily anomalies for a given month.

使用 griddap 从网格数据集请求数据和图表

griddap允许您通过特殊格式的 URL 从网格数据集中请求数据子集、图表或地图（例如，来自卫星的海面温度数据）。griddap 使用OPeNDAP (external link)

数据访问协议 (DAP ) (external link)

及其投影约束

。

URL 指定您想要的内容：数据集、图表或数据子集的描述以及响应的文件类型。

（简单）您可以使用数据集的数据访问表单获取数据。它会为您生成 URL。
（简单）您可以使用数据集的“制作图表”表单制作图表或地图。它会为您生成 URL。
（不难）您可以绕过表格并获取数据，或者通过手动生成 URL 或使用计算机程序或脚本来制作图形或地图。

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.
