Data quality can be measured by some special spectro radiometer with wavelength specification or in environmental lab we can measure the water quality parameter. Water quality kit also available.
@ Selvaraj , thanks for your message. I'm aware of this, but I'm looking at the dataset because I'm not working on a real-experiment that uses sensors to measure water properties.
Hi Essa Q. Shahra , I have just found datasets search engine where you can fine most likely all the published datasets related to water, ocean, fisheries, geophysics ,etc. I found several recent datasets in regarded to your question.
