(a) Comparison of Soil Moisture Active Passive (SMAP) sea surface salinity (SSS) and in-situ salinity data of I-ORS for the period 2015–2020, (b) relationship between Yangtze River discharge and surface salinity observed at I-ORS. The red dashed line represents the least-squares linear regression (surface salinity = − 7.3656 × 10⁻⁵ river discharge + 32.9391, p-value = 2.3165 × 10⁻⁸), and (c) spatial distribution of monthly mean of SMAP SSS (psu) for April 2015 to March 2020; asterisk indicates location of I-ORS.
