MODIS Terra Annual NDVI Phenology at 500m Resolution

Global vegetation phenology data derived from the MODIS/Terra satellite. The dataset provides annual, gap-filled, and smoothed Normalized Difference Vegetation Index (NDVI) values at a 500-meter spatial resolution. It is produced by the LAADS organization from the MOD09A1 8-day Surface Reflectance product and stored in HDF format with a sinusoidal projection.

Use Cases

• Tracking annual vegetation phenology cycles using the smoothed NDVI time series.
• Monitoring global land surface changes and vegetation health at 500m resolution.
• Analyzing the impact of climate variability on growing seasons.
• Providing input data for ecological and agricultural yield models.

Strengths

• Provides consistent, gap-filled NDVI data, improving analysis continuity.
• Offers global spatial coverage at a 500-meter resolution.
• Data is processed and distributed by the authoritative LAADS organization.

Limitations

• Specific row count, file size, and temporal range are not provided by any source.
• Sources conflict on license details, with one specifying 'other-license-specified' and another listing 'None'.
• Column names and a precise data collection methodology are unavailable.
