Coverage=/group/sub-group/sub-sub-group/dataset

WCS: Used to specify the coverage to be processed. Specifies the subset data layer or group for Parameter Subsetting. Multiple datasets can be specified separated by commas. 

The dataset value always starts with a slash and the group-subgroup hierarchy are separated with slashes. If only a group or subgroup is specified, all lower level datasets are included in the processing. 

Bbox=<W>,<S>,<E>,<N>

WCS: Bounding Box used for spatial subsetting. Coordinates are in decimal degrees. This is the same order as used for the CMR spatial filter parameter

Time=<start_datetime>,<end_datetime>

WCS Keyword: Specify data datetime range filter for the CMR query. 
Note, the Time keyword is a shared CMR/egi keyword that also invokes temporal subsetting/stitching for applicable data sets.

WCS: Used for Temporal subsetting.
Note: The Time keyword also is used as a CMR temporal filter.

SUBSET=time("<datetime>")
SUBSET=lat(<min>,<max>)
SUBSET=lon(<min>,<max>)
SUBSET=x(<min>,<max>)
SUBSET=y(<min>,<max>)

WCS: SUBSET=time("<datetime>") is used for Temporal subsetting with the datetime as the specified start time.

WCS: Minimum and Maximum values to be used for the Bounding Box for spatial subsetting. Coordinates are in decimal degrees(lat/lon) or in meters(x/y).

Format=<format>

WCS: Optional output file format specifier used for re-formatting. Supported values vary by data type.
[GeoTIFF, HDF-EOS5, NetCDF4-CF, NetCDF-3, ASCII, HDF-EOS, KML, Shapefile] 
If this parameter is not used, then the output format is the same as the input format (no reformatting).

BoundingShape=<GeoJSON content>

Optional, used for polygon subsetting. 
GeoJSON content string. 
Note: When drawing a polygon that crosses Anti-Meridian, need to redefine negative longitude values to > 180, vise versa, positive longitude values to < -180 in order for it to render correctly and for ogre to convert it correctly to geojson format.

page_size=<n>

This is a CMR parameter to control the number of granules in the page of returned results. 

Discussion: When there are multiple granules returned from the CMR query, they are returned in sets called pages. The default page size is 10 granules. The page_size KVP allows the user to change the page size. Multi-page results can be accessed one page at a time using the page_num KVP described below. 

Note that the system configuration parameter MAX_GRANS_FOR_SYNC_REQUEST limits the size of a request in EGI. Exceeding that number returns an error. Page_size should always be set to less than or equal to this request limit.

See the FAQ for more discussion. 

page_num=<n>

This is a CMR parameter to select the page of results to be processed. The page contains the number of granules selected in the page_size KVP. 

Version=1.0.0

WCS Clients Only: Indicates WCS Version 1.0.0 compatibility (optional) 

Request=GetCoverage

WCS Clients Only: Identifies the type of WCS request (optional) 

token=<token>

Allows the user to provide an Earthdata Login token. This token is used as proof that the user has been authenticated by the Earthdata Login system. It is used for:

• enabling user access to ACL protected granule rsults in CMR
• enabling Programmatic Access delivery of results only to authenticated users
• metrics collection
