H-ESC Bespoke EUHFORIA model run

Case Study Request - Bespoke Enlil run

The H-ESC has capacity to run a limited number of 3D MHD Enlil runs to support specific case studies. Requests are processed by the UK Met Office under a fair usage agreement. Jobs are run sequentially. Note that the runs have to be accommodated outside operational scheduled runs and therefore cannot be provided in support of near-real-time analysis or assessment at the current time. This product is therefore most appropriate for post event analysis or simulating possible event scenarios.

Please note that this product is no longer available and any requests submitted from 1st March 2023 will not be processed. Please consider the use of models provided through the VSWMC as an alternative.

To make a request please use the form below. Specify a start date (this will be used to select the background solar wind conditions). Then supply zero, one or more CME characteristics that will be included within the Enlil MHD propagation into the solar system. Ensure that you include all requested parameters and that the launch times fall within the simulation time frame (-7 days < T < +5 days).

Currently only a standard run is available providing output from -2 days < T < +5 days and results out to 2AU. The resulting Enlil files will be E-mailed to your registered SSA/SWE e-mail address so please ensure that this is current.

Date (T) for background solar wind

Enter CME parameters, you can use the +/- buttons to add or remove more CME characteristics. The information required for each CME is:

UTC time at which the CME reaches 21.5 Rs
The HEEQ longitude of the CME in degrees
The HEEQ latitude of the CME in degrees
The half width of the CME in degrees
The speed of the CME at 21.5 Rs in km/s

This information is usually obtained from analysis of coronagraph images

Add CME characteristics (please ensure that you select the background solar wind time first)

Please note that Enlil runs are computationally expensive and rely on manual operation by UKMO staff and therefore test or product availability runs should be avoided. Runs submitted with default parameters may be rejected for this reason. An archive of Enlil output with the prevailing conditions HPARC/PB is also available.
