Forecast Data Availability

When can I expect a model run to be available?

The table below lists the usual time delay between a model run starts and when the first model file is available and when the complete model is available in STAC-API and EDR-API.

For example, for the model run at 2024-08-23T00:00:00, the first model file is usually available at +1h35m (2024-08-23T01:35:00) and the complete model is available at +2h45m (2024-08-23T02:45:00)

 

What causes the delay of forecast data in the APIs?

Timing depends on a lot of factors:

• Which model
  Downstream models (DKSS and WAM) arrive later, as the input for their runs is the output from other models.
  
   
• Which time range you need
  Data is made available one time step at a time in order, so later time steps are made available last
  
   
• Which type of modeldata you need
  Surface levels (sf) is small files, so faster. Model level (ml) is large files - so slower
  
   
• The network load of the day
  During night time files arrive faster

 

How can I see when data was available?

You can find yourself when the data you need is generally available by requesting like this:

https://dmigw.govcloud.dk/v1/forecastdata/collections/<MODEL>/items?api-key=<api-key>&modelRun=<modelRun> (external site)

and look at the json key properties.created when that data was available.
