Analysis of data gathered in Deir Al Qamar
Graph showing Visibility VS Days for data gathered in Deir Al Qamar :
Looking at the graph we can notice that the mean visibility value is 12.1175 km.
Highest peak at a visibility of 16.1 km during 6 and 8 March and 20 April.
Lowest peak at a visibility of 6.4 km during 24 and 25 March.
Such an image is the image we took on March March 6, with the highest visibility. In this image one can notice how clear the sunset is and how visible a large distance is.
However take this image for instance which was taken at the same time, from the same place, except was found to have the lowest visibility (6.4 km) . As can be seen the large distance that was clearly visible in the first image, is barely shown in the second (look at the buildings close to the sea for example) . This is known as "haze".
Thus, when analysing your own image of the sunset, make sure to check to what degree long distances are clearly visible. If there is no clarity , then be sure that the visibility is low, signifying a large concentration of particles and molecules that are not healthy (as mentioned in the dust analysis previously).
