RASOR and DRIHM platform combine to support modelling of the impact caused by Hurricane Matthew in the western part of Haiti.
The DRIHM platform was able to simulate the wind pattern from the Hurricane using Hi-res WRF Meteorological modelling simulation. The WRF model was run, using Grid and super computing computational resources that are easily accessible through the DRIHM portal. Wind fields, served in standardized format (NETCDF-CF) are then easily imported into the RASOR platform that allows to compute the impact caused by the wind gusts. Exposure was extracted from the Copernicus activation products and further characterised in the RASOR platform to be used for Vulnerability assessment.
The impact was computed for the different hit sites in Haiti. RASOR also allows the user to transform categorical damage available from EO analysis (in this case provided by Copernicus EMS) into economica damage. This allowed the comparison between the “observed” and “modelled” damage in Haiti.
For the western part of Haiti the match between the model estimate and the one derived from observation stays within 20 percent. This is an indication that the DRIHM-RASOR modelling framework can provide with 3 days lead time a reasonable estimate of damage that can be used in a preparedness framework.
