Document Type: Statement

The HydroMet division of NiMet routinely monitors flood and drought in all the states of Nigeria using the Standardized Precipitation Index (SPI). Standardized Precipitation Index (SPI) expresses the actual rainfall as a standardized departure from the rainfall probability distribution function and, hence, this index has gained importance in recent years as a potential drought indicator permitting comparisons across space and time. Hydrometeorological information plays a vital role in the orderly and efficient development and control of water resources. It provides information for assessing, developing, and managing the water-related environment. The basic orientation, therefore, is to make available qualitative hydrometeorological information and products to end users in all aspects of human endeavor in fulfillment of the mandates of the Agency.
