@zohra_mozafari We have different ways of accessing data via tools or the command line. Do you mind letting us know how you searched for the data, so we understand where you had difficulty?

how did you download this file?

Hi,

Thanks for letting us know. After you make your selections from the dropdown boxes (sensor, product, period, resolution) can download the images (.png) or data files (.nc) and then click the image you are interested in below. You should see links to SMI (mapped image) BIN (binned image) and the png file for download. You can also use the help pages (Click red help button) if you have more questions.

Just a note that you can use the Giovanni tool with MODIS-Aqua chlorophyll data and create seasonal time-series for a user-specified region, and also create seasonal averages of the data.
