NCSS parameters table

Parameter Name

Required

Constraints

Description / possible values

default

var

yes

Variables must be in the dataset description

Name of variables, separated by ',' (comma).

 

point

no

 

Means a grid will be treated as a point dataset making the request a Grid As Point request and allowing the extraction of point data from grids

false

latitude

no

Must be provided if point=true and must be within the lat/lon box declared in the dataset description

In Grid As Point requests latitude of the point

 

longitude

no

Must be provided if point=true and must be within the lat/lon box declared in the dataset description

In Grid As Point requests longitude of the point

 

north

no

bounding box must have north > south

Used to define a bounding box. Bounding box must have all 4 parameters: north, south, east and west

If no bounding box is specified returns the whole grid

south

no

bounding box must have north > south

Used to define a bounding box. Bounding box must have all 4 parameters: north, south, east and west

If no bounding box is specified returns the whole grid

east

no

bounding box must have east > west; if crossing 180 meridian, use east boundary > 180

Used to define a bounding box. Bounding box must have all 4 parameters: north, south, east and west

If no bounding box is specified returns the whole grid

west

no

bounding box must have east > west; if crossing 180 meridian, use east boundary > 180

Used to define a bounding box. Bounding box must have all 4 parameters: north, south, east and west

If no bounding box is specified returns the whole grid

time

no

Must be a time within the dataset time range

Time as a W3C date or "present". The time slice closest to the requested time is returned

If no time or time range is provided returns all the times within the dataset

time_start

no

 

Used to specify the starting time of a time range. Time as a W3C date or "present". Two of time_start, time_end, time_duration must be present to define a valid time range.

If no time or time range is provided returns all the times within the dataset

time_end

no

 

Used to specify the ending time of a time range. Time as a W3C date or "present". Two of time_start, time_end, time_duration must be present to define a valid time range.

If no time or time range is provided returns all the times within the dataset

time_duration

no

 

Used to specify the time duration of a time range. Duration as a W3C time duration. Two of time_start, time_end, time_duration must be present to define a valid time range.

If no time or time range is provided returns all the times within the dataset

timeStride

no

Only for grid requests

Take only every nth time in the available series

1

horStride

no

Only for grid requests

Take only every nth point (both x and y)

1

vertCoord

no

Requested variables must have the same vertical levels otherwise ambiguous results are likely.
The specified vertical level must lie within the declared range in the dataset description if not the response will contain NaN values

 

If the requested variables have vertical levels, all the vertical levels will be returned

accept

no

Accepted values for grid request are netCDF and for grid as point requests csv, xml, netCDF

Used to specify the returned format. Supported formats are netCDF for grid requests and csv, xml and netcdf for grid as point

Grid requests netcdf, Grid as point requests csv
