Global Phytoplankton Fluorescence Data for Harmful Algal Bloom Detection

Fluorescence Line Height (FLH) data quantifies red chlorophyll-a fluorescence emitted by phytoplankton. The dataset provides a global binned product derived from PACE OCI satellite observations, processed by the OB_CLOUD organization. The specific version is 3.1.

Use Cases

• Detect and track harmful algal blooms (HABs) by analyzing elevated nflh values in satellite imagery.
• Identify productive ocean waters by mapping spatial patterns of the nflh variable.
• Assess phytoplankton physiological status by interpreting variations in the fluorescence line height signal.
• Validate and improve ocean-color algorithms by comparing nflh data with in-situ fluorescence measurements.

Strengths

• Provides a specific geophysical variable (nflh) for phytoplankton fluorescence analysis.
• Designed for global-scale monitoring of ocean biological activity.

Limitations

• Data uncertainties increase in optically complex coastal and inland waters, as noted in the description.
• Specific row count, temporal coverage, and spatial resolution are unknown from the input.
