The Fluorescence Line Height (FLH) data suite quantifies red chlorophyll-a fluorescence emitted by phytoplankton. It is used for harmful algal bloom detection, tracking productive waters, and assessing phytoplankton physiology. The dataset is produced by NASA Earthdata and includes variables like normalized fluorescence line height and instantaneous photosynthetically available radiation.
Use Cases
- Detect and track harmful algal blooms based on elevated fluorescence line height values.
- Identify productive waters for fisheries or ecological studies based on phytoplankton fluorescence.
- Assess phytoplankton physiology and stress in marine environments based on fluorescence measurements.
- Analyze uncertainties in ocean-color products for coastal and inland waters.
Strengths
- Includes a specific geophysical variable: normalized fluorescence line height (nflh).
- Includes a specific geophysical variable: instantaneous photosynthetically available radiation (ipar).
- Describes a clear application for harmful algal bloom detection and tracking.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
