Info
titleWIWB_async: download disclaimer

The amount of data in one WIWB request (download option) also has its maximum. This maximum data request is limited to the currently installed WIWB-server (internal) memory capacity, which is 12 GB. This means that an individual data request can not exceed this size. This maximum of 12 GB is valid per data request, since all data requests are processed sequentially. If the data request is too large, the server runs out of memory and this data requests fails. Delft-FEWS reports that an error has occurred at the WIWB-server side. To download the requested data, the user needs to split up the data request. A common approach would be to reduce the number of timesteps. Note that the requested view period can never exceed a period of one year, as this is limited by WIWB.

Below, three examples of benchmark data requests are given. These examples stay within the current WIWB-server limits and will be successful. Please use these as inspiration for your own data requests.
