Water Quality Data

Chlorophyll-a concentration mostly use to identify water quality. This data takes from Venice Lagoon, Italy.

• The water quality analyses focuses on assessing the effect of the lockdown and the subsequent economic recovery on inland and coastal water quality by monitoring the deviation from a climatological mean of Chlorophyll-a concentration over a number of key Areas of interest.

• Green dots - lower than the climatological mean (in black), indicating good water quality.

• Blue dots - Greater than the climatological mean but still inside the climatological variability, indicating regular water quality.

• Red dots - beyond the climatological variability, indicating poorer water quality.

From this graph, we can perceive, in high restriction time, the Chlorophyll-a is low than low restriction time.
