VIIRS/NPP Vegetation Indices: Monthly Global 1km Satellite Data

NASA/NOAA Suomi NPP satellite data provides monthly global vegetation indices at 1-kilometer resolution. The dataset includes three primary indices—Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), and Enhanced Vegetation Index-2 (EVI2)—alongside reflectance bands for red, blue, green, near-infrared, and shortwave infrared, plus quality and angular layers. It is designed to continue the long-term Earth Observation System mission, succeeding MODIS products.

Use Cases

• Monitoring drought stress and crop health using NDVI and EVI time series.
• Analyzing canopy cover dynamics and forest phenology based on EVI sensitivity.
• Comparing vegetation models using the three-band EVI and two-band EVI2 reflectance data.
• Assessing data quality for specific geographic analyses using the provided pixel reliability layers.

Strengths

• Provides three distinct vegetation indices (NDVI, EVI, EVI2) for comparative analysis.
• Includes multiple supporting data layers (reflectance bands, angles, quality) beyond the core indices.
• Designed for continuity with the long-term MODIS mission, supporting time-series analysis.

Limitations

• Missing coverage for two specific tiles (h33v07 and h18v14) over water due to critical input gaps.
• Key metadata such as row count, column names, and exact temporal coverage are unavailable across all sources.
• License is ambiguously specified as 'other-license-specified' without clear terms.
