This table provides metadata for the actual indicator available from Armenia statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from Armenian statistics, this table should be consulted for information on national methodology and other Armenian-specific metadata information.

Indicator description

14.3.1global indicator is mainly based on observations that contain/limit the carbon system required to determine the variability of water acidity in a water management zone. The carbon system in this context refers to 4 main measurable indicators. pH (sliding scale hydrogen ion concentration), CT (total dissolved inorganic carbon), pCO2 (partial pressure of carbon dioxide) and AT (total alkalinity). Only pH is presented as a national indicator.
