3-day cumulative USF AFAI Fields (USF AFAI 3D AOML), 2016-present
Listed in NOAA UAF (Unified Access Framework)
3-day cumulative University of South Florida (USF) AFAI Fields.
Description
AFAI: Alternate Floating Algae Index (in reflectance units) to detect ocean surface features such as Sargassum, green macroalgae, and cyanobacteria. AFAI is estimated by Chuanmin Hu (USF).
AFAI is sensitive to detect subtle ocean surface features, but it saturates under sun glint, clouds, or thick aerosols. Reference: Hu, C., L. Feng, R. F. Hardy, and E. J. Hochberg (2015). Spectral and spatial requirements of remote measurements of pelagic Sargassum macro algae.
