资源简介:
This data set contains decadal (1950, 1960, 1970, 1980, 1990 and 1995) estimates of gridded fossil-fuel emissions, expressed in 1,000 metric tons C per year per one degree latitude by one degree longitude. The CO2 emissions are the summed emissions from fossil-fuel burning, hydraulic cement production and gas flaring. The years 1950 to 1990 were developed and compiled using somewhat different procedures and information than the 1995 data. The national annual estimates (Boden et al., 1996) from 1950 to 1990 were allocated to one degree grid cells based on gridded information on national boundaries and political units, and a 1984 gridded human population map (Andres et al., 1996). For the 1995 data, the population data base developed by Li (1996a) and documented by CDIAC (DB1016: Li, 1996b) was used as proxy to grid the 1995 emission estimates. There is one *.zip data file with this data set at 1.0 degree spatial resolution.
本数据集涵盖了自1950年至1995年每十年一次的网格化石燃料排放估算,以每年每千吨碳计,单位为每度纬度与每度经度。二氧化碳排放量包括化石燃料燃烧、水硬水泥生产和天然气燃烧的总排放量。1950年至1990年的数据基于与1995年数据有所不同的程序和信息进行开发和编制。1950年至1990年的国家年度估算值(Boden 等人,1996年)基于国家边界和政治单元的网格信息,以及1984年的网格人口地图(Andres 等人,1996年)分配到每度网格单元。1995年的数据则利用Li(1996a)开发的且由CDIAC(DB1016:Li,1996b)记录的人口数据库作为替代数据,以网格化1995年的排放估算值。本数据集包含一个空间分辨率为1.0度的*.zip数据文件。
