Datasets:

* Estimated Tropical Cyclone Wind Impacts and Severities: This dataset is generated by the Kinetic Analysis Corporation's TAOS ^(TM) model and provided as a subscription service to the Pacific Disaster Center. Kinetic Analysis Corporation uses the TAOS^(TM) modeling platform to produce estimates of speeds and their impact along the projected track of a tropical cyclone. Estimated wind impacts are obtained directly from the TAOS^(TM) Estimated Wind Impacts data and are based on a modified Beaufort Wind Scale.
return to exposure * * Total Exposure Counts and Percentages: Total exposure counts are based on the number of units in the assessed category estimated to be exposed to the hazard. Percentages are calculated based on the estimated number of units exposed to each level of severity as a percent of the total number of units estimated to be exposed to the hazard.
return to exposure Population and Residential Units: Population is derived from 2010 Landscan population data. The number of residential units per cell is estimated by dividing the Landscan population by the Average Household Size reported for each country. Due to data constraints, exposure estimates will not include information on residential units for the following countries and territories:
Aland Islands, Antarctica, Baker Island, Bouvet Island, Cocos (Keeling) Islands, Curacao, Democratic Republic of the Congo, Faroe Islands, French Southern and Antarctic Lands, Glorioso Islands, Heard Island and McDonald Islands, Howland Island, Ivory Coast, Jarvis Island, Johnston Atoll, Juan De Nova Island, Midway Islands, Montserrat, Paracel Islands, Saba, Saint-Barthélemy, Saint-Martin, South Georgia and the South Sandwich Is, Spratly Islands, St. Pierre and Miquelon, St. Vincent and the Grenadines, Svalbard and Jan Mayen Islands, Holy See, Wake Island, and Western Sahara. Due to data constraints, some small areas of land and some islands may not be included in the exposed residential units assessment, though population exposure may be reported.

Land Cover and Land Usage: Land Cover and Land Usage are categories are derived from MODIS satellite imagery.
