MRSM0.25°: A High-Resolution Global Ocean Subsurface Salinity Dataset integrating multi-source remote sensing data
Listed in ScienceDB
This product was reconstructed using a dense upsampling and downsampling network with adaptive weight adjustment, based on multi-task learning.
Description
It integrated multisource satellite remote sensing data (sea surface salinity [SSS], sea surface temperature [SST], absolute dynamic altitude [ADT], and the sea surface wind field, which can be decomposed into northward and eastward components [USSW and VSSW]), in situ salinity profile and ORAS5 reanalysis data.
The dataset demonstrates high accuracy, with an average R² of 0.987 and RMSE of 0.100 PSU when validated against observational profiles, and effectively captures fine-scale ocean salinity structures.Time Range: 1993.01-2023.12Region: GlobalLongitude: 180°W~180°ELatitude: 78.375°S~78.375°NParameters: SalinityHorizontal Resolution: 0.25° × 0.25°Vertical Resolution: 23 levels (30-2000 m)Temporal Resolution: monthlyStorage Format: netcdf
