Climatology deals with the study of the climate and its effects on human health and various economic sectors. Climate is subject to inherent variability. During the last century, however, human activity has considerably altered the chemical composition of our atmosphere and a direct result is an increasing greenhouse effect. The study of consequent climate changes is a new area of investigation for climatology.

NIM now has climate observations that date back to the early 20th century. After collection and validation, the data is processed and stored. All data from 1950 onward is available on magnetic support. Such climate database is managed by an information system that comprises software and analysis tools so as to enable internal and external users to use NIM climate data. The database will thus provide users with the desired information in the shortest time possible.

Analysis of the principal climate elements (temperature, precipitation, moisture, evaporation, etc.) has made it possible to identify the major climate features of our country. Other research activities concerning the climate trends in Tunisia during the previous century are also in progress.

Applied meteorology.
Applied meteorology is the use of meteorological data to elaborate useful products (bulletins and specific studies) destined to the various sectors of economic activities particularly agriculture and hydrology.

It can provide helpful assistance to:
    agriculture and farming.
    irrigation planning and management.
    fight against diseases and natural disasters (drought, frost, hail, forest fire, etc.).

Hydrometeorology It can :
    be of helpful assistance to the various domains of hydrology.
    provide basic data for hydraulic works (sanitation, dams, drainage, etc.).
    contribute to elaborate statistics for rain.
