MODIS Terra Gap-Filled LAI and FPAR 8-Day Global Dataset

MODIS/Terra Gap-Filled, Smoothed Leaf Area Index (LAI) and Fraction of Photosynthetically Active Radiation (FPAR) 8-Day L4 Global 1km SIN Grid product provides satellite-derived vegetation parameters. The dataset is composited every 8 days at 1-kilometer resolution on a Sinusoidal grid and is used for calculating surface photosynthesis, evapotranspiration, and net primary production. It is produced by the LAADS organization and was last updated in March 2026.

Use Cases

• Modeling terrestrial net primary production using gap-filled LAI and FPAR parameters.
• Calculating surface evapotranspiration for hydrological and climate models.
• Analyzing global vegetation phenology and health trends from 8-day composited time-series data.
• Assimilating satellite-derived LAI into land surface models to improve carbon cycle estimates.
• Studying the relationship between absorbed photosynthetically active radiation and canopy structure.

Strengths

• Provides gap-filled and smoothed data, enhancing usability for continuous time-series analysis.
• Offers global coverage at a 1-kilometer spatial resolution, suitable for regional to continental-scale studies.
• Features an 8-day temporal compositing period, balancing noise reduction with phenological capture.

Limitations

• Specific column names and the total row count are not provided by any source, limiting detailed schema understanding.
• Sources conflict on license information, with one specifying 'other-license-specified' and another listing 'None'.
• The exact temporal range of data collection is not specified across the platforms.
