The National Atmospheric Research Laboratory (Hindi: राष्ट्रीय वायुमण्डलीय अनुसंधान प्रयोगशाला) (NARL) is an autonomous Research Institute funded by the Department of Space of the Government of India. NARL is engaged in fundamental and applied research in the field of Atmospheric Sciences. The research institute was started in 1992 as National Mesosphere-Stratosphere-Troposphere (MST) Radar Facility (NMRF). Over the years many other facilities such as Mie/Rayleigh Lidar, Lower atmospheric wind profiler, optical rain gauge, disdrometer, automated weather stations etc. were added. The NMRF was then expanded into a research institute and renamed as National Atmospheric Research Laboratory on 22 September 2005.
