SAFARI 2000 Biogenic VOC Emissions from Southern African Flux Towers

Southern African biogenic volatile organic compound (BVOC) emissions were measured at flux tower sites in Maun, Botswana and Skukuza, South Africa during the 2001 wet season campaign. The dataset includes flux measurements from two ecosystems, species-level isoprene emission screening for 95 African plant species, and concurrent meteorological and CO2 data. It was collected by NASA investigators to support the development of a regional BVOC emissions model.

Use Cases

• Modeling regional BVOC emissions using species-level isoprene emission capacity data.
• Analyzing correlations between BVOC fluxes and concurrent meteorological measurements like temperature and wind speed.
• Studying ecosystem-level gas exchange by linking BVOC and CO2 flux measurements from the same towers.
• Comparing emission profiles between Colophospermum mopane woodland and Combretum-Acacia savanna ecosystems.
• Calibrating leaf-level emission models with physiological data from the nursery plant screening.

Strengths

• Includes species-level isoprene emission screening for 95 distinct African plant species.
• Provides concurrent BVOC flux, CO2 flux, and meteorological data from two distinct southern African ecosystems.
• Data collection employs the relaxed eddy accumulation (REA) technique for flux measurements and a leaf cuvette technique for plant screening.

Limitations

• Key structural details like row count, file size, and specific column names are unavailable across all sources.
• There is a significant conflict in the 'last updated' date between platforms (2001 vs. 2026), casting doubt on metadata maintenance.
