THE GLOBAL BIOSPHERE EMISSIONS AND INTERACTIONS SYSTEM (GLOBEIS)

Example Application

Figure 1: Comparison of biogenic isoprene emissions for the Houston, Texas area from GLOBEIS (top impage) with high-resolution biomass density data rendered as 4 km grid cells and BEIS2 (bottom image) with county-level biomass density data rendered as 16 km grid cells. GLOBEIS is able to resolve the difference between hardwood forests in river valleys (red - high emission rate) and the east Texas "piney woods" between the river valleys (green). Areas of low isoprene emissions (e.g., crops, urban land) are also sharply differentiated (blue). In contrast, the BEIS2 inventory is unable to resolve details at the sub-county level because the emissions are based on county-level biomass density data.
