Density Gradient Data Policy
The density gradients data are supported by NASA Ocean Salinity Science Team. While the data are freely accessible, your acknowledgements help us to demonstrate the value of this dataset to the scientific community. Your acknowledgements are also needed to ensure we get continuous support from NASA to maintain the salinity gradient website. When using these data in a publication, we request that the following acknowledgement be given:
“Density gradient data are produced by Earth & Space Research and sponsored by the NASA Ocean Salinity Science Team. Data are available at https://www.esr.org/data-products/salgrad“
Density gradient calculated from Level-4
We provide monthly global density gradient data files using temperatire from GHRSST Level 4 AVHRR_OI Global Blended Sea Surface Temperature Analysis and Salinity from SMOS and SMAP.
The monthly datasets are available at: https://salinitydata.org/files/data/monthly/Density/
