A service has been developed to visualize and download retrievals from the CPP algorithm for the full MSG disk covering the past two weeks.
The services have been implemented according to specifications of the Open Geospatial Consortium (OGC) and can be used for free. The services work independently of the provided portal, e.g. anybody can use the services directly in their own viewer by using the service links provided in this page.
The services can be viewed directly in the web portal, for example:
ADAGUC and OGC Web Services
The spatial data infrastructure is based on OGC compliant web services. These web services include Web Mapping Services (WMS) for online visualization and Web Coverage Services (WCS) for downloading raster data. The MSG-CPP data is produced in the network common data format (NetCDF) with Climate and Forecast (CF) conventions and then offered in the OGC services.
The high resolution of the images and the large data volumes are challenging for real-time and web based visualization services. The ADAGUC OGC server has been optimized to enable quick rendering of visualizations from NetCDF data. The server reads the NetCDF4 files directly and interpolates the data to the desired geographic projection and location. A feature of the server is the support for NetCDF flag values and flag meanings as specified in the CF conventions.
OGC Web Map Service (WMS) URLs
Using this request an XML file with description of the OGC WMS service is obtained:
- https://msgcpp-adaguc.knmi.nl/adaguc-server?dataset=msgrt&service=WMS&request=getcapabilities (XML file)
Example GetMap Request
Here is a GetMap request of the most recent global radiation image on a country map (baselayer).
OGC Web Coverage Service (WCS) URLs
Using this request an XML file with description of the OGC WCS service is obtained:
- https://msgcpp-adaguc.knmi.nl/adaguc-server?dataset=msgrt&service=WCS&request=getcapabilities (XML file)
Example GetCoverage Request
This is a request with which data can be interpolated, subsetted, reprojected and converted to different formats. In the example URL below, the current (latest available) precipitation rate is projected to latitude-longitude projection (EPSG:4326). An area of longitudes between 0 and 15 and latitudes between 45 and 60 containing 100x100 pixels is selected. The requested file format is NetCDF.

OpenDAP and FTP
Since the upgrade to version 2 in March 2021 access via OpenDAP and FTP is no longer available.
