Project Objectives
The main objectives of the project are:  

  1. to find water quality algorithms optimized for APEX which can be implemented into the APEX PAF   and  
  2. to automatically generate accurate concentration maps of chlorophyll, CDOM and suspended matter

Methodology
Generally seen there are 4 big steps which can be differentiated: (i) Initially a database containing SIOPS information from different inland and estuarine water regions will be developed. The SIOPS database will form the basis for the simulation of realistic APEX images of inland water scenes. (ii) This simulated data will be used for algorithm development and validation of APEX water quality products. Beside known methods like Matrix inversion and Linear Least Square Approach, an innovative approach based on Wavelet based curve fitting will be tested and validated. (iii) Hyperspectral imagery will be collected with the APEX sensor over 2 test sites, accompanied with extended field measurements to fine-tune the selected algorithm. (iv) This algorithm will be implemented in the APEX Processing and Archiving Facility to automatically produce water quality products for the end-user community.

(Expected) Results

  • The main outcome will be water quality algorithms optimized for the APEX sensor and integrated into the CDPC.
  • An indication of the sensitivity of the inversion models to errors in the input data.
  • A successful APEX flight with high quality imagery.
  • A good quality estimate of the final water quality products is expected.
