Client and user comments from authorities
“Understanding the transport processes of suspended
sediments in waterways is essential to reduce river
engineering expenses such as dredging. As the federal
authority BAW is responsible for the German waterways,
…
“The EOMAP satellite turbidity products enable a
harmonized and objective measure on various
temporal and spatial scales of the federal river
system … beyond the in situ measurement systems
capabilities …

NASA MIP
2011/08/19
NASA concentrations are higher in shallow waters but lower in deep
waters compared to MIP
MIPs filter algorithms seem more flexible to MODIS sensor failures
Near-coastal areas are sometimes processed by MIP but not by NASA

Spatial and temporal analysis - FLH
2011/07/11 2011/08/12
FLH seems suitable to indicate HAB occurrence.
Limiting factors of this method:
Weak spectral signal at the required MODIS wavelength
Other environmental signals influence FLH increases
Max. spatial resolution of 1000 m
