What is exceedance?

Exceedance refers to situations where a parameter or value crosses a certain limit or threshold, either in terms of quality, quantity, or frequency. It may refer to exceedance of environmental standards, financial limits, risk thresholds, or any other kind of benchmark.

For example, in the context of air pollution, exceedance occurs when the concentration of a pollutant exceeds the permissible level set by regulatory agencies. Similarly, in finance, exceedance may refer to situations where a company or investment portfolio exceeds the designated level of risk or draws more funds than it can afford.

Exceedance is often used as a measure of the performance or compliance of a system or process. In many cases, exceeding the limit can have detrimental effects on the system or environment, and corrective actions may be necessary to mitigate the impact.
