NASA's Terra MODIS Level-3 Global Binned Fluorescence Line Height (FLH) Data quantifies red chlorophyll-a fluorescence emitted by phytoplankton. The dataset likely contains global, binned measurements of normalized fluorescence line height (nflh) and instantaneous photosynthetically available radiation (ipar). It is produced by the OB_CLOUD organization and is version 2022.0.
Use Cases
- Detect and track harmful algal blooms based on elevated fluorescence line height values.
- Identify productive waters based on phytoplankton fluorescence intensity.
- Assess phytoplankton physiology based on chlorophyll-a fluorescence measurements.
- Analyze photosynthetically available radiation for ocean productivity studies.
Strengths
- Quantifies a specific geophysical variable (chlorophyll-a fluorescence) used for ecological monitoring.
- Includes a normalized fluorescence line height (nflh) and instantaneous photosynthetically available radiation (ipar) variable.
- Data is from a major satellite mission (Terra MODIS) and is a Level-3 global binned product.
Limitations
- Uncertainties increase in optically complex coastal and inland waters, as noted in the description.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file formats are unknown, which may limit suitability assessment.
