Volcanic Ash Advisory Models

National Environmental Research Institute Denmark

The graphics show the amount of air pollution from ground level until 20 km height on a relative scale, where red is the most polluted. The difference between the colours is a factor 10. NERI has assumed that the volcano has emitted the plume to a height of 5-7 km. Please note that the model works in UTC-time. Central European summertime = UTC + 2 hours.

ESA Model

  • ESA Model for Ash Deposition This animation shows the movement of the ash plume from the eruption of the Eyjafjallajoekull glacier in Iceland.

NILU Model

Norwegian Institue for Air Research - Model - The animations shows dispersion of the eruption from the volcano Eyjafjallajökull.

The animation from Oslo and Bergen also includes the episode from Thursday April 15, where citizens in Bergen and Oslo reported they could smell sulfphur from the eruption in Iceland.

The information in the models has been derived by a model using SO2 as particle tracer for the ash plume. Please note that the time is given in UTC and that the model only includes emissions after 1700 on April 14.

NOAA Visualization

  • Animation of volcanic plume impacting Europe - The data shows the concentration of ash in the atmosphere. The ash mass is calculated by combining multiple spectral channels from the EUMETSAT Meteosat-9 satellite's SEVIRI sensor. The latest image from April 19, 2010 is derived from the NASA Aqua/MODIS satellite sensor. These analyses, developed by NOAA scientists, can distinguish between clouds and other atmospheric aerosols.

EO-1 Hyperion

From Stu Frye: EO-1 Hyperion image from yesterday [4/17] of the Iceland volcano shown as two side-by-side panels produced from two different spectral ranges,...the left one is SWIR and the right one is visible. In the SWIR, you can see the thermal vent and in the vis you can see the plume coating everything to the SouthEast making the ice brown/gray

ASTER

This Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) expedited view of the Eyjafjallajökull Volcano was acquired at 12:51 UTC on April 19, 2010 from a 705-km altitude on the Terra spacecraft. The image was generated using ASTER registered radiance at the sensor data, with visible and near-infrared (VNIR) bands simulating natural color. The ground resolution is 15 m. A billowing white and gray plume emanating from Eyjafjallajökull is visible drifting to the south and covering a large area. Expansive snow-covered areas appear white. Vegetation is visible in shades of green, with water dark blue. A density slice overlay using 90 m ground resolution thermal infrared (TIR) band 14 at 10.95 to 11.65 µm wavelengths approximates relative temperatures. The hottest pixels are portrayed in yellow, representing the highest TIR band 14 digital numbers in this scene. While still hot, the TIR pixels colored orange and red are at relatively lower temperatures. Another hot area representing an earlier and now-cooling flow is evident northeast of Eyjafjallajökull at Fimmvörduháls.
