Northern Hemisphere Carbon Uptake Period and GPP Data from 104 Flux Towers, 1995-2014

Gross primary productivity (GPP) observations from 104 FLUXNET and ChinaFLUX sites, encompassing 862 site-years across the Northern Hemisphere. The dataset includes derived metrics for the carbon uptake period (CUP) start, end, and duration, analyzed from 1995 to 2014. It was authored by Zhaogang Liu and last updated on figshare in April 2026.

Use Cases

• Modeling the relationship between growing season length and ecosystem productivity based on CUP and GPP metrics.
• Analyzing latitudinal gradients in growing season timing based on CUP_start and CUP_end data.
• Investigating climatic drivers of carbon uptake based on correlations with mean annual temperature and precipitation.
• Studying interannual variability in ecosystem carbon cycling across different biomes like tropical, arid, polar, and alpine regions.

Strengths

• Data is derived from 104 flux tower sites, representing 862 site-years of observations.
• Explicitly covers a 20-year time range from 1995 to 2014.
• Includes analysis of dominant climatic factors (MAT and MAP) influencing the carbon uptake period.

Limitations

• Row count and specific column definitions are unknown, requiring inspection after download.
• The dataset is small at 81.4 KB, indicating a limited scope, likely containing summary or processed results rather than raw flux data.
• Geographic coverage is limited to the Northern Hemisphere.
