Hi! I am a student, and I am learning to use the chlorophyll data to identify some submesoscale phenomenons.
I learnt that Level-2 product good to identify that.
I need a specific resolution number of this dataset, but I cannot find it in this website:
https://oceancolor.gsfc.nasa.gov/data/10.5067/JPSS1/VIIRS/L2/OC/2018/

I mean, some datasets may be shown that their spacial resolution is 1 km, time resolution is 1 day. But I don't get the SPECIFIC RESOLUTION of this dataset. If I need to cite this dataset, how can I describe its resolution?

Could anyone help me? THANKS A LOT!

The spatial resolution for L2 JPSS-1/NOAA 20 is 750 m. On this webpage (https://www.nesdis.noaa.gov/current-satellite-missions/currently-flying/joint-polar-satellite-system/jpss-mission-and), it says JPSS covers the entire globe twice a day.

You can always find the spatial resolution and much more information about the NASA ocean color products by opening the images in SeaDAS and click the "Global_Attributes" under Metadata of the images. Such as the following screen shot.

Got it! Thank you so much!
