Global 15 x 15 Minute Grids of the Downscaled GDP Based on the SRES B2 Scenario, 1990 and 2025

The Global 15x15 Minute Grids of the Downscaled GDP Based on the Special Report on Emissions Scenarios (SRES) B2 Scenario, 1990 and 2025, are geospatial distributions of Gross Domestic Product (GDP) per Unit area (GDP densities). These global grids were generated using the Country-level GDP and Downscaled Projections Based on the SRES B2 Scenario, 1990-2100 data set, and CIESIN's Gridded Population of World, Version 2 (GPWv2) data set as the base map. First, the GDP per capita was developed at a country-level for 1990 and 2025. Then the gridded GDP was developed within each country by applying the GDP per capita to each grid cell of the GPW, under the assumption that the GDP per capita was uniform within a country. This data set is produced and distributed by the Columbia University Center for International Earth Science Information Network (CIESIN).

本数据集为基于《排放情景特别报告》（SRES）B2情景的降尺度GDP的全球15x15分钟网格数据，该数据集展示了每单位面积国内生产总值（GDP密度）的地理空间分布。该全球网格数据是通过利用基于SRES B2情景的1990-2100年国家层面GDP降尺度预测数据集以及CIESIN世界人口网格化数据集第二版（GPWv2）作为基础地图生成的。首先，在1990年和2025年，对每国人均GDP进行了编制。随后，在各国内部，通过将人均GDP应用于GPW的每个网格单元，在假设人均GDP在国境内均匀分布的前提下，编制了网格化GDP。本数据集由哥伦比亚大学国际地球科学信息网络中心（CIESIN）制作与分发。
