Natural VOC Emissions Inventory on a One-Degree Global Grid

Monthly emissions data for 1990 provides inventories of isoprene, terpenes, and other reactive volatile organic compounds on a one-degree latitude by longitude grid. The dataset was compiled by the Global Emissions Inventory Activity (GEIA) under the International Global Atmospheric Chemistry project. Each file contains up to 64,800 data points representing grid cells.

Use Cases

• Model tropospheric OH concentration and methane growth rates using isoprene and terpene emission values.
• Compare natural VOC emissions from plant foliage and marine sources against anthropogenic inventories using the specie values per grid cell.
• Study the role of NVOCs in the global carbon cycle by analyzing monthly emission patterns across the 360 x 180 grid.
• Assess emissions from geological hydrocarbon reservoirs and microbial decomposition using the 'other VOC' (OVOC) data fields.

Strengths

• Global spatial coverage on a standardized one-degree latitude by longitude grid.
• Monthly temporal resolution for the year 1990 provides seasonal emission patterns.
• Includes specific inventories for key compounds: isoprene, terpenes, ORVOC, and OVOC.

Limitations

• Data is temporally stale, representing only the year 1990.
• Unknown row count, column names, and sample size limit reproducibility checks.
• Potential geographic bias from the modeling and inventory methods of the 1990s.
