Matthew's GISS Methane from Rice Cultivation

High-resolution global databases on the geographic and seasonal distribution of rice cultivation and associated methane emission, compiled by Matthews et al. (1991), have been archived for public use. These data were developed to evaluate the role of rice cultivation in the annual emission of methane from terrestrial sources. The databases represent an integration of extensive information on the cultivation of rice in all 103 rice-producing countries of the world and reflect conditions for 1984.

The suite of 1-degree latitude/longitude resolution databases includes locations of rice cultivation, monthly arrays of actively growing rice areas, countries and political subdivisions, and monthly arrays of methane emission from rice cultivation.

由马修斯等学者（1991年）编纂的高分辨率全球水稻种植地理分布与相关甲烷排放数据集已归档并供公众使用。该数据集旨在评估水稻种植在全球陆地源甲烷年排放中所扮演的角色。数据集汇集了关于全球103个水稻生产国的水稻种植广泛信息，并反映了1984年的相关状况。该系列1度经纬度分辨率的数据库包括水稻种植地点、活跃生长水稻区域按月排列、国家和地区，以及水稻种植产生的甲烷排放按月排列。
