Abstract: National Atmospheric Research Laboratory (NARL), a unique site having Mesosphere Stratosphere Troposphere (MST) Radar, Lower Atmospheric Wind Profiler (LAWP), Lidars, disdrometer, Optical Rain Gauge, Automatic Weather Station, vertical profiling with GPS soundings, and a dual frequency GPS receiver, has been operating all these instruments to support the scientific research dealing with dynamics of the lower, middle and upper atmosphere, coupling between these regions and precipitating systems. Several interesting results have been obtained making use of the experimental facilities at NARL. It is, indeed, a difficult task to review all of them in a short paper. In this communication, an attempt has been made; however, to review the exciting scientific outcome resulted from Indian MST radar LAWP measurements, confining ourselves to dynamical and microphysical aspects of atmospheric processes in the troposphere and lower stratosphere. A variety of atmospheric phenomena occurring over a wide range of temporal and spatial scales are discussed, starting from microscale turbulence within the radar resolution volume to mesoscale processes, like convection and associated processes, and to synoptic and planetary scale waves with proper referencing, wherever required.
