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
