NRL NAAPS for DescribeCoverage

   <CoverageDescription>

• Title=NOGAPS and NAAPS fields in press coordinate
• Abstract=none
• Identifier=NAAPS

   <ows11:Title>NOGAPS and NAAPS fields in press coordinate</ows11:Title>
   <ows11:Abstract></ows11:Abstract>
   <Identifier>NAAPS</Identifier>

• Latitude and Longitude bounds in EPSG:4326 and WGS 84 projections. This is regardless what the data projection is.

   <ows11:WGS84BoundingBox crs="urn:ogc:def:crs:OGC:2:84">
       <ows11:LowerCorner>-179.0000 -89.5000</ows11:LowerCorner>
       <ows11:UpperCorner>+180.0000 +89.5000</ows11:UpperCorner>
   </ows11:WGS84BoundingBox>

• Grid bounds and size in the WGS 84 projection, it's the only currently supported projection.

   <GridCRS>
       <GridBaseCRS>urn:ogc:def:crs:OGC:2:84</GridBaseCRS>
       <GridType>urn:ogc:def:method:WCS:1.1:2dSimpleGrid</GridType>
       <GridOrigin>-179.0000 -89.5000</GridOrigin>
       <GridOffsets>+1.0000 +1.0000</GridOffsets>
       <GridCS>urn:ogc:def:cs:OGC:0.0:Grid2dSquareCS</GridCS>
   </GridCRS>

• Time dimension

   <TimePeriod>
       <BeginPosition>2007-05-09T00:00:00Z</BeginPosition>
       <EndPosition>2007-05-20T00:00:00Z</EndPosition>
       <TimeResolution>PT6H</TimeResolution>
   </TimePeriod>

• Fields of Coverage. The example is the second on the list.

   <Field>

• • Human Readable Title

       <ows11:Title>specific humidity - nogaps</ows11:Title>

• • Machine Readable Identifier

       <Identifier>sphu</Identifier>

• • Data Definition. Value can be any number, datatype is IEEE 32 bit float and Units Of Measure ia g/g ratio

       <Definition>
           <ows11:AnyValue/>
           <ows11:DataType>float</ows11:DataType>
           <ows11:UOM>(g/g)</ows11:UOM>
       </Definition>

• • IEEE standard for not a number.

       <NullValue>nan</NullValue>

• • Currently no interpolation is allowed. List of Interpolations

       <InterpolationMethods>
           <Default>none</Default>
       </InterpolationMethods>

• • Elevation dimension, values from 1000 to 10 mbar.

       <Axis identifier="elev">
           <ows11:Title>elevation</ows11:Title>
           <AvailableKeys>
               <Key>1000.0</Key>
               <Key>975.0</Key>
               <Key>950.0</Key>
               ....
               <Key>20.0</Key>
               <Key>10.0</Key>
           </AvailableKeys>

• • Human readable meaning of the axis. The netCDF-CF has axiscode "Z" for elevation and depth dimension, so we use it.

           <ows11:Meaning>Z</ows11:Meaning>

• • Type and Units Of Measure

           <ows11:DataType>double</ows11:DataType>
           <ows11:UOM>mbar</ows11:UOM>
       </Axis>
   </Field>

At the very end:

• Supported Coordinate Systems, at the very end, linear lat-lon urn:ogc:def:crs:EPSG::4326 and lon-lat urn:ogc:def:crs:OGC:2:84

   <SupportedCRS>urn:ogc:def:crs:EPSG::4326</SupportedCRS>
   <SupportedCRS>urn:ogc:def:crs:OGC:2:84</SupportedCRS>

• Supported Formats: image/netcdf and application/x-netcdf are the same, netCDF-CF. There is a need to standardize this format.

   <SupportedFormat>image/netcdf</SupportedFormat>
   <SupportedFormat>application/x-netcdf</SupportedFormat>
