Overview
Imports grid time series data from Cmems NetCDF files.
Import Configuration
An example of the CMEMS import will be given here.
The type of import should be configured using the DATA_TYPE property:
- DATA_TYPE should be set to "HOURLY" for hourly data.
- DATA_TYPE should be set to "DAILY" for daily data.
- DATA_TYPE should be set to "MONTHLY" for monthly data.
This example is configured to import 2D Hourly grids for the last 24 hours:

The following example is configured for importing daily 3D grids:

The following example is configured for importing monthly 3D grids:
<import>
<general>

Id Map Configuration
An example of the IdMapping used for the NETCDF-CF_GRID import is shown below.
IdImportNetCDF 1.00 default.xml
<idMap version="1.1" xmlns="http://www.wldelft.nl/fews" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.wldelft.nl/fews http://fews.wldelft.nl/schemas/version1.0/idMap.xsd"> <parameter internal="Wind.u" external="uo"/> <parameter internal="Wind.v" external="uv"/> </idMap>
Grids Configuration
When importing grids in the FEWS database it is required to configure the grid characteristics in the grids.XML file. The grid characteristics must be similar to the grid imported from the NetCDF file.
Grids 1.00 default.xml
<regular locationId="CMEMS_2D"> <rows>241</rows> <columns>265</columns> <geoDatum>WGS 1984</geoDatum> <firstCellCenter> <x>43</x> <y>28</y> </firstCellCenter> <xCellSize>0.0833</xCellSize> <yCellSize>0.0833</yCellSize> </regular>
