This dataset includes an estimation of the annual physical exposition to tropical cyclones of Saffir-Simpson category 5.
It is based on three sources:
1) IBTrACS v02r01 (1969 - 2008, http://www.ncdc.noaa.gov/), year 2009 completed by online data from JMA, JTWC, UNISYS, Meteo France and data sent by Alan Sharp from the Australian Bureau of Meteorology.
2) A GIS modeling based on an initial equation from Greg Holland, which was further modified to take into consideration the movement of the cyclones through time.
3) A population grid for the year 2010, provided by LandScanTM Global Population Database (Oak Ridge, TN: Oak Ridge National Laboratory).
Unit is expected average annual population (2010 as the year of reference) exposed (inhabitants).
This product was designed by UNEP/GRID-Europe for the Global Assessment Report on Risk Reduction (GAR). It was modeled using global data.
