I think nasa site can help you

You may download  global sea surface salinity data from Copernicus Marine Environment and monitoring  (CMEMS site)

Hi Zohreh,

SMOS satellite from ESA is doing this kind of measurements. You can hev a look at SMOS website.

Soil Moisture & Ocean Salinity (SMOS) could be a right choice for you.

the following link has more information on SMOS data: https://earth.esa.int/web/guest/missions/esa-operational-eo-missions/smos/content/-/asset_publisher/t5Py/content/how-to-obtain-data-7329

Good luck

Dear Kulkarni

I download the data but it does not cover the Caspian Sea region unfortunately. The Spatial resolution (0.08*0.08 deg) is much better than data given from Aquarius satellite (1 deg), However both of them do not cover the study area. You can see in the picture here that no data (SSS) were measured for this region.

Thank you for your help.

Dear  Gherboudj 

Thank you, I registered to access MIR_OSUDP2 data (Level 2 Sea Surface Salinity product). I downloaded netCDF format but t faced to new problems. First: the data can not be decoded by the software (I try to open it by SeaDAS, ArcMap and IDRISI)!! Second: I checked whether the satellite swept Caspian Sea, specially mu study area before getting data but when I click on that special link and open "browse image", I found that no data was measured based on the legend!!! Does it mean the satellite does not cover the region? Do you have any suggestion? 

Thank You

Zohreh

It is only possible to open the smos data as a snap program they developed.
