The MOD13C2 product provides monthly global vegetation indices at a 0.05-degree resolution. LPCLOUD generates this Level 3 dataset by temporally averaging MOD13A2 products to create cloud-free composites. It includes primary layers for Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI).
Use Cases
- Analyze NDVI and EVI trends over time to monitor global vegetation health and biomass.
- Use VI QA, reflectance, and angular data fields to assess data quality and sensor conditions.
- Employ spatial statistics like mean and standard deviation of NDVI for regional climate impact studies.
- Compare NDVI continuity index with historical NOAA-AVHRR data for long-term vegetation change analysis.
Strengths
- Provides global coverage on a Climate Modeling Grid of 3,600 rows and 7,200 columns.
- Includes two primary vegetation indices (NDVI and EVI) with improved sensitivity over high biomass regions.
- Offers multiple data fields including VI QA, reflectance, angular information, and spatial statistics.
Limitations
- Specific row count, column count, sample size, and temporal coverage are not provided.
- Known issues exist, requiring users to consult external assessment websites for details.
