sesnor : MODIS-Aqua.

If not possible on this platform, please guide me, on how to get it

There are many ways to get the data you need. We provide reflectance, but it's not difficult to get normalized water-leaving radiance from reflectance.
You can do search and download: https://oceancolor.gsfc.nasa.gov/data/download_methods/
For monthly and/annual mean, you can also use level 3/4 browser: https://oceancolor.gsfc.nasa.gov/l3/
