Temporal and Spatial Distribution of Atmospheric CH4 Concentration and Estimation of Animal Husbandry Emissions in Hebei Province.

Methane is the world's second largest greenhouse gas after carbon dioxide, accounting for about one-sixth of the total greenhouse gas emissions. Due to the development of animal husbandry, carbon dioxide and methane produced in the process of animal husbandry breeding have gradually become one of the important sources of the greenhouse effect. The research of methane gas emissions from animal husbandry is of great significance to sorting out the sources of greenhouse gases. This paper is aimed at Hebei Province, using TROPOMI sensors onboard Sentinel-5P, TANSOFTS onboard GOSAT observation data, and the related ground station data. The main research content: (1) The temporal and spatial distribution characteristics of methane in Hebei Province from 2009 to 2020; (2) The proportion of methane emissions from ruminants in Hebei Province Estimate using ruminant methane emission formula. The average proportion is 6.10% from 2009 to 2018.
