Global Cyclone Proportional Economic Loss Risk Deciles

The Global Cyclone Proportional Economic Loss Risk Deciles is a 2.5 minute grid of cyclone hazard economic loss as proportions of Gross Domestic Product (GDP) per analytical Unit. Estimates of GDP at risk are based on regional economic loss rates derived from historical records of the Emergency Events Database (EM-DAT). Loss rates are weighted by the hazard's frequency and distribution. The methodology of Sachs et al. (2003) is followed to determine baseline estimates of GDP per grid cell. To better reflect the confidence surrounding the data and procedures, the range of proportionalities is classified into deciles, 10 class of an approximately equal number of grid cells of increasing risk. This data set is the result of collaboration among the Columbia University Center for Hazards and Risk Research (CHRR), International Bank for Reconstruction and Development/The World Bank, and Columbia University Center for International Earth Science Information Network (CIESIN).

全球热带气旋经济损失风险比例十分位数据集，以2.5分钟网格为单位，展示了热带气旋风险经济损失相对于国内生产总值（GDP）的比例。该数据集的风险GDP估计值基于从历史应急事件数据库（EM-DAT）中提取的区域经济损失率，并通过风险频率和分布进行加权。遵循Sachs等（2003年）的方法论，确定每个网格单元的基线GDP估计值。为了更准确地反映数据和方法的不确定性，将比例范围划分为十分位，即按风险递增的网格单元数量大致相等的10个等级。本数据集是哥伦比亚大学灾害与风险研究（CHRR）中心、国际重建与发展银行/世界银行以及哥伦比亚大学国际地球科学信息网络（CIESIN）中心合作的成果。
