Application of Ocean Salinity Satellite on Agriculture Remote Sensing: Research Progress

Ocean salinity satellite has the potential to conduct global remote sensing monitoring in the fields such as marine fishery, soil moisture in cultivated land, etc. Method] Starting from three aspects of current development of salinity satellites, marine fishery, and application of soil moisture remote sensing in cultivated land, the paper summarizes the progress of previous studies on salinity satellite agricultural remote sensing monitoring and inversion. Results]In conclusion, in the study field of marine fisheries remote sensing, application of salinity satellites mainly rely on the studies of temperature and salinity inverse algorithms. Such fundamental studies provide necessary factors for the studies of remote sensing monitoring applications in marine fisheries; In the soil moisture study field, salinity satellite application is relatively mature, and based on the precision analysis under different land cover conditions, development of inverse algorithms suitable for the production of soil moisture products is the foundation for remote sensing monitoring of soil moisture content in cultivated land. Conclusion] By summarizing the current progress of application of ocean salinity satellite on agricultural remote sensing, the paper analyzes the future development direction of the field, and provides the agricultural application basis for the research and development of the new generation of ocean salinity satellites.
