Chlorophyll-a concentration

Data: daily near real-time and reprocessed data from the Copernicus Marine Service satellite products in the Atlantic Ocean (L4, 1 km).

Diagnostics: maps and timeseries of regional daily means (since 2021) - monthly means (since 2015) - annual means (since 1998).

Extreme events: detection of high primary productivity through the daily monitoring.

Ocean variability (since 2021)

Timeseries of regional daily chlorophyll-a concentration for the current year, the last 3 years and the mean over the period 1998-2015.
High primary productivity spikes (when values become higher than 90% of the historical data) are highlighted for the current year.
