Moderate Resolution Imaging Spectroradiometer (MODIS) chlorophyll algorithm has
widely been used to estimate chlorophyll concentration. This study evaluates the
performance of standard MODIS chlorophyll algorithms in Malaysian waters and
development of chlorophyll algorithms for Southern South China Sea (SSCS). In situ
data of chlorophyll and reflectance, Rrs, were collected in Straits of Malacca (SoM)
and SSCS. Comparison between in situ and satellite measurements of chlorophyll
reveals that the global algorithm does not work well in both study areas. The global
algorithm tends to overestimate in situ chlorophyll in SoM and underestimate in SSCS.
Result also revealed that the tuned algorithm provide a more accurate estimation of
chlorophyll in the study area with low percentage errors. Based on the overall findings,
the application of regional algorithm could allow in identifying the presence of
phytoplankton and the ecosystem health in the study area.
