Editing Soil salinity severity index (section)

== Monitoring and Measurement ==
Monitoring soil salinity severity involves a combination of field sampling, proximal sensing, and remote sensing technologies. Soil electrical conductivity measurements from soil samples or in situ sensors provide direct estimates of salt concentration. Remote sensing platforms, including satellite and airborne sensors, enable large-scale mapping of salinity by detecting spectral signatures associated with salt-affected soils. Institutions such as agricultural research centers and environmental monitoring agencies utilize these methods to assess salinity patterns. Advances in sensor technology and geospatial analysis have improved the temporal and spatial resolution of salinity monitoring, enhancing the ability to track changes over time.

Within the SIGNAL system, this phenomenon is treated as a defined environmental signal whose boundaries and measurement conventions are described below.
