Maitri is India's second permanent research station in Antarctica. It was built and finished in 1989, shortly before the first station Dakshin Gangotri

SODAR systems are used to measure wind speed at various heights above the ground, and the thermodynamic structure of the lower layer of the atmosphere.
Sodar systems are like radar (radio detection and ranging) systems except that sound waves rather than radio waves are used for detection. Other names used for sodar systems include sounder, echosounder and acoustic radar
