Question 10
At which main application areas is the sensor aimed?
Marine uses
List 2 specific projects, where they have been reported, their goals and their outcomes.
Project 1: MOS-1/1b MESSR Observations of the Antarctic Sea Ice: Ice Bands and Ice Streamers
Goal
In the Antarctic Ocean, ice bands can be often seen not only at the ice edge but also in the ice interior zone throughout the year and they extend for hundreds of kilometres in the latitudinal direction. So the goal of the project is to see if the width and spacing of ice bands tends to decrease from winter to summer.
Outcome
The MESSR data showed that the band with and spacing of the ice decreased from winter to summer. The width of an ice band is 2-6km in August and September and 0.1-0.7km in December. Then the spacing of the ice bands is 3-10km in August and September but 0.1-2km in December. But it is noted from the MESSR data that sea ice can be observed only on cloud-free conditions, which may introduce some bias in drawing general features. Furthermore, MOS-1/1b satellites have low temporal resolution, with a recurrent period of 17 days. To minimize such defects, the combined use of other satellite data such as SSM/I, NOAA AVHRR and SAR data may be helpful for future investigation.

Project 2: MOS Data to Assess Water Quality in Small Lakes
Goal
The main goal of this study was to assess the technical feasibility of using MESSR data to evaluate the general water quality of small lakes, using experimental test sites like lakes in the Piedmont region of North West Italy.
Outcome
The low value observed in the green and red part of the spectrum for reflectance in the Moncenisio lake is too low for a clear mountain lake and then shows an over correction that must be changed in later approaches. Also the relative difference between the low altitude polluted lakes and the high mountain lakes is coherent with the difference in water quality that was present in previous tests proving that the MESSR data was correct.
