I can't find daily data over a year of the chlorophyll chla parameter from the MODIS sensor for a fixed geographical point.
(knowing that when I downloaded I found a data for one day for each month which is normal because the satellite passes over the same point after 24 days or so, but the other days we have no data ???)
Please give me a clear answer because I have searched a lot and I am confused

Where are you looking for this data? You can select a desired time range, choose a geographical point, and select a period (daily, monthly, etc). https://oceancolor.gsfc.nasa.gov/l3/
