Detailed information

Product description:	Volcanic ash occurrence within a radius of 150km around a volcano. Occurrences are computed by using a large number of particles distributed on the contaminated vertical column and subjected to wind advection and deposition process on the ground (sedimentation). Horizontal dispersion is estimated using vertical wind distribution. The wind field is provided by the IFS meteorological model. Occurrences are computed by Météo-France for aeronautical support, available for 18 pressure levels in hPa (1000, 950, 900, 850, 800, 700, 600, 500, 400, 300, 250, 200, 100, 70, 50, 30, 20) and for aeronautic flight levels FL0-FL200, FL200-FL350 and FL350-FL550. Occurences are computed on a regular horizontal grid 0.1deg x 0.1deg around the source by cutting out according to the quantiles or by using a linear manner. As a result, a visualization of the total ash cloud cover, and an estimation of areas of greater density, are provided. Outputs are in GRIB format. Data access is restricted to institutional authorities.
