Fluorescence Line Height (FLH) data quantifies chlorophyll-a fluorescence from phytoplankton, derived from NASA's Aqua MODIS satellite. The dataset includes the normalized fluorescence line height (nflh) and instantaneous photosynthetically available radiation (ipar) as geophysical variables. It is produced by OB_CLOUD and represents version 2022.0.
Use Cases
- Detect and track harmful algal blooms (HABs) by analyzing elevated nflh values in satellite imagery.
- Identify productive ocean waters by correlating nflh measurements with phytoplankton activity.
- Assess phytoplankton physiology by examining the relationship between nflh and ipar data fields.
- Study spatial and temporal patterns in chlorophyll-a fluorescence using the global mapped FLH data.
Strengths
- Global spatial coverage from the Aqua MODIS satellite sensor.
- Includes two specific geophysical variables: nflh and ipar.
Limitations
- Uncertainties increase in optically complex coastal and inland waters.
- Specific row count, column details, and temporal range are unknown.
Provenance

- Collection Method
- Derived from satellite-measured water-leaving radiance, computed as the height above a spectrally interpolated baseline.
- Time Range
