Global Phytoplankton Fluorescence Line Height Data for Harmful Algal Bloom Detection

Fluorescence Line Height (FLH) data quantifies red chlorophyll-a fluorescence emitted by phytoplankton, a key indicator of biological activity. This global mapped dataset from NASA's PACE OCI mission provides the normalized FLH variable for detecting harmful algal blooms and assessing phytoplankton physiology. The data is produced by the OB_CLOUD organization using the version 3.1 algorithm.

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 in the nflh fluorescence signal.
• Assess phytoplankton physiological status by interpreting variations in the nflh metric.
• Study coastal water optical complexity by examining areas where nflh values are known to be reduced.

Strengths

• Provides a specific geophysical variable (nflh) for phytoplankton fluorescence analysis.
• Data is derived from NASA's PACE OCI mission, a dedicated ocean color satellite.
• Algorithm is documented as version 3.1, indicating a defined processing standard.

Limitations

• Uncertainties increase in optically complex coastal and inland waters, limiting reliability in those regions.
• Specific row count, spatial resolution, and temporal coverage are unknown from the provided information.
• The dataset description notes FLH values can be reduced in complex waters, which may complicate interpretation.
