Reader - HYCOM-GLBa0.08

Deprecated - Use HycomReader ReaderName: HycomReader (to be changed to include the product name)

This reader is used to import data from HYCOM GLBa0.08 product. The description of the dataset can be found here.

The imported dataset will have the following properties:

  • The spatial domain is transformed into a mesh in EPSG:4326. The mesh is composed of mostly equidistant and non-equidistant grid in the lower two thirds of the world, and a bipolar projection in the upper third (above 40 deg N). For more information about this spatial domain see for example this link.
  • The input files should cover the whole spatial domain (importing only a limited extent of the world is not supported).
  • The input files should contain only variables that are all 2 dimensional (without layers) or all 3 dimensional (all with layers). The sample data that was intended to be used with this reader either contains only some number of 2d variables (such as ssh, mixed_layer_density and so on) per file, or a single 3d variable defined with 33 layers (such as temperature) in one file. Each of these files should be imported separately, into a dedicated dataset (until a merging strategy is provided so that all variables from multiple files could be stored within a single dataset).
  • Due to potentially high number of variables in the 2d files it is advisable to filter the items so that only relevant data is actually stored. This can be achieved using a reader parameter called AllowedItemNames. An example request might look like this:
        {
          projectId: <projectId>,
          uploadUrl: <fileUrl>,
          outputDatasetData: {
            name: <dataset-name>
          },
          readerName: 'HycomReader',
          writerName: 'MDWriter',
          readerParameters: [
            {
              name: 'AllowedItemNames',
              value: '["ssh"]'
            }
          ]
        }
