ABOUT
National Atmospheric Research Laboratory in Gadanki Village, Tirupati, Andhra Pradesh, India and NARL is an autonomous research laboratory fully funded by the Department of Space, Government of India. The centre was established in 1992. NARL is involved in Atmospheric and Space Sciences by carrying out fundamental and applied research. NARL starts as the National Mesosphere-Stratosphere-Troposphere (MST) Radar Facility. NARL is managed by a Governing Council with Secretary, DOS as the Chairman and Director, NARL as member secretary. It is one of the prime centres for atmospheric research in India. Prime work as a state-of-the-art MST radar, Sodium Lidar, Optical Rain Gauge, etc.

RESEARCH AND DEVELOPMENT GROUPS
1) Aerosols, Radiation and Trace Gases Group
Aerosols, Radiation and Trace Gases Group (ARTG) is a group which is involved in research of atmospheric aerosols, trace gases, radiations, clouds and their interactions. The small sub-micron size particles known as aerosols which are produced from a variety of man-made as well as natural processes such as vehicle exhaust, waste-burning, wind-blown dust, volcanic eruptions etc.
ARTG group has a long-term project to research on atmospheric aerosols, trace gases and clouds and their consequences on the earth's radiation budget and clouds using observations and modelling.
2) Atmospheric Structure and Dynamics Group
Atmospheric Structure and Dynamics Group focuses to evaluate and detect the atmosphere through exact, long-term, and comprehensive sensing by using radio and optical waves both by active and passive means. Interests and areas of research of the group involves, research of Middle Atmospheric Dynamics with special priority on tropospheric and lower stratospheric structure and dynamics and on mesosphere and lower thermosphere.
3) Clouds and Convective Systems Group
The clouds and convective systems group research on the microphysics and dynamics of clouds, precipitation and other huge impact on weather systems. An important priority is given to the understanding of the genesis, structure and interaction of these systems with the ambient environment. The organisation is actively involved in understanding the small-scale processes happening near the tropical and extratropical tropopause, boundary layer processes and their connection to the generation of convection, monsoon dynamics, in general, active and break spells, in particular.
4) Computers and Data Management Group
To initiate a data center as per International norms and control the data archival & data dissemination processes. To invent, organize and control the network infrastructure and all other IT operational facilities. To form and evolve industry standard web based and desktop software application packages for in-house uilization and distribution.
5) Ionospheric and Space Physics Group
Ionospheric research at NARL was commenced dated back in 1993 using the high power 53 MHz radar located at Gadanki, commonly known as mesosphere-stratosphere-troposphere (MST) radar. This is one of the powerful radar of this kind in the world that is situated at magnetically low latitude (6.4oN magnetic latitude) but well exterior to the equatorial electrojet belt (3o magnetic latitude). We look for to understand the structure, energetics, and dynamics of the ionosphere and the systems that couple it so as to define the future state of the ionosphere finer. A crucial feature is added in the recent time is the studies related to the space weather.
