Global Population Distribution (1990),Terrestrial Area and Country Name Information on a One by One Degree Grid Cell Basis

This data base contains gridded (one degree by one degree) information on the world-wide distribution of the population for 1990 and country-specific information on the percentage of the country's population present in each grid cell (Li, 1996a). Secondly, the data base contains the percentage of a country's total area in a grid cell and the country's percentage of the grid cell that is terrestrial (Li, 1996b). Li (1996b) also developed an indicator signifying how many countries are represented in a grid cell and if a grid cell is part of the sea; this indicator is only relevant for the land, countries, and sea-partitioning information of the grid cell. Thirdly, the data base includes the latitude and longitude coordinates of each grid cell; a grid code number, which is a translation of the latitude/longitude value and is used in the Global Emission Inventory Activity (GEIA) data bases; the country or region's name; and the United Nations three-digit country code that represents that name.

本数据库收录1990年全球1°×1°网格化人口分布数据，以及分国家的各网格单元内该国人口占该国总人口的百分比数据（Li, 1996a）。其次，本数据库包含两项面积统计指标：一是各网格单元内属于该国的领土面积占该国总领土的百分比，二是该网格单元内属于该国的陆地面积占该网格单元总陆地面积的百分比（Li, 1996b）。Li (1996b) 还开发了一项指示指标，用于标识单个网格单元内包含的主权国家数量，以及该网格单元是否属于海域；该指标仅与网格单元的陆地、国家及海域划分信息相关。第三，本数据库涵盖各网格单元的经纬度坐标、经纬度值转换得到的网格编码（该编码可用于全球排放清单活动（Global Emission Inventory Activity, GEIA）数据集）、所属国家或地区名称，以及对应名称的联合国三位数字国家代码。如需获取数据文件，请点击此链接前往二氧化碳信息分析中心（Carbon Dioxide Information Analysis Center, CDIAC）数据转换网站：http://cdiac.ess-dive.lbl.gov/ftp/db1016/
