Southern Africa Biogenic Emissions Model Outputs for 2001

Southern Africa's biogenic volatile organic compound emissions were modeled for the year 2001 using the GLOBEIS model. The dataset provides monthly estimates for isoprene, monoterpenes, and other VOCs by land cover and vegetation type, derived from GIS layers of vegetation, leaf area index, and climate data. It was developed by NASA for the SAFARI 2000 regional science initiative.

Use Cases

• Analyzing seasonal variation in isoprene emissions across southern Africa using monthly estimates.
• Mapping the distribution of light-dependent monoterpene emissions by land cover category.
• Correlating vegetation type with stored monoterpene emission rates.
• Validating regional atmospheric chemistry models with gridded biogenic emission outputs.
• Studying the impact of temperature and cloud cover data on modeled VOC fluxes.

Strengths

• Emissions are modeled for a full year (2001) on a monthly basis, providing seasonal coverage.
• Integrates multiple validated input sources including vegetation data, LAI (1987-88 ISLSCP), and NOAA temperature data.
• Output includes specific estimates for four constituent groups: isoprene, light-dependent monoterpene, stored monoterpene, and other VOCs.

Limitations

• Key metadata conflicts exist: the last update date is listed as both 2026-03 12 (datagov) and 2001-12-31 (nasa_earthdata).
• Core structural details like row count, column names, and dataset size are unknown across all platforms.
