FIFE Surface Flux Baseline 92 Derived Data Set

Mid-May through mid-October 1987 data collected from 21 stations across 19 sitegrids in the FIFE study area. This derived dataset compiles original surface flux measurements, including latent and sensible heat flux, with flagged spikes and checks for energy imbalances. It was compiled by NASA and compares observed flux data to model results.

Use Cases

• Analyzing diurnal cycles of latent and sensible heat flux from surface stations.
• Validating land surface model outputs against quality-controlled observational data.
• Studying spatial variability of surface energy fluxes across a heterogeneous landscape.
• Investigating energy balance closure issues at Bowen ratio measurement sites.

Strengths

• Data spans a significant growing season from mid-May to mid-October 1987.
• Includes quality control procedures to flag erroneous spikes in heat flux time series.
• Compares flux measurements from Bowen ratio sites against model results for consistency.
• Collected from a network of 21 stations across 19 sitegrids, providing spatial coverage.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date: datagov lists 2026-03-12, while nasa_earthdata lists 1987-10 -19.
