SiB3 Modeled Global Hourly Carbon Flux 1998-2006

Hourly carbon flux data estimates the global net ecosystem exchange (NEE) between the atmosphere and terrestrial biosphere from 1998 to 2006. The dataset contains 9 years of modeled hourly flux values for 14,637 land points on a 1-degree Cartesian grid, produced using the Simple Biosphere Model, Version 3 (SiB3). Data is provided by NASA in NetCDF and GeoTIFF formats, processed and distributed by the ORNL DAAC.

Use Cases

• Validating atmospheric transport models like TransCom using the monthly-mean flux comparisons.
• Analyzing seasonal and diurnal cycles of biosphere-atmosphere carbon exchange using the hourly time-series data.
• Mapping global spatial patterns of carbon sinks and sources using the 1-degree geospatial grid data.
• Studying long-term interannual variability in terrestrial carbon fluxes across the 1998-2006 period.

Strengths

• Model outputs were validated against independent TransCom flux data for 2000-2005, with results generally within error bars.
• Provides high temporal resolution with hourly estimates over a 9-year period (1998-2006).
• Offers data in multiple standard formats (NetCDF, CF-compliant NetCDF, GeoTIFF) with provided processing code (FORTRAN).

Limitations

• The exact row count, dataset size, and specific column names are not provided across any platform.
• Sources conflict on the last updated date: one lists 2026-03 -12, another lists 2006-12-31.
• The license is specified only as 'other-license-specified' without detailed terms.
