Grímsvötn
Special Forecast products for Grímsvötn produced through the SAVAA project
The eruption at Grimsvötn has ceased and no plume has been visible on radar since ~0200UTC on 25 May 2011.
Ash emissions in the current model forecast end at 0900 UTC on 25 May.
| This page provides background information for special FLEXPART products generated for the eruption of Grímsvötn in 2011. We have set up the FLEXPART forecast system to provide updated forecasts. Services provided here have been developed largely through funding from the European Space Agency (ESA) to NILU's SAVAA project. |

FLEXPART Forecast Products
Below are quicklinks to our static forecasts provided during the Grímsvötn Eruption (May 2011). Links to static tracer forecasts using the transport model FLEXPART are provided in the table below. Please read this important information first before using the model products.
Static snapshots of trajectory and tracer plots are produced by the forecast system every six hours. For more plotting control and closer inspection of forecasts output, we recommend to use this interactive tool for plotting FLEXPART
Please report any questions or problems to: John Burkhart and Andreas Stohl
Concentration Plots
Concentration plots for FLEXPART Tracers separated by tracer, and altitude. PSV indicates the passive (no removal) tracer. VO represents a 'volcanic aerosol' tracer. Wet and dry deposition removal processes are included. This is an idealized tracer, and has NOT been validated. Click the
