The terrestrial biosphere plays an important role in the global carbon cycle link with climate change, the main cause of global warming. Mongolian ecosystems are particularly vulnerable due to the relatively high altitude of the country and the continental semi-arid climate. Therefore, it is important to monitor environmental changes. So far, many studies have analyzed terrestrial vegetation changes in Mongolia using a single satellite-based vegetation index, datasets, such as MODIS and GIMMS datasets. However, synthesis analysis using ground observation, remote sensing, and ecosystem modeling is missing.

The purpose of this study is to show robust vegetation and terrestrial carbon cycle changes using multiple available datasets of climate, vegetation, and carbon cycles, covering ground observation, remote sensing datasets, and model outputs. This study covers periods from the 1980s to 2020.
