Brief Description (Abstract):

Probing the lowest 1 km of the planetary boundary layer over ocean is important for various practical purposes, and to understand the dynamics of atmosphere over ocean. This is achieved on continuous basis by an acoustic sounder which captures the thermal picture of the atmosphere, on a time-height scale on continuous basis. We have designed and developed shipborne acoustic sounders which were installed on the ships M.V. Thuleland and M.S. Brinknes. These ships sailed to Antarctica from Goa as part of the Indian Scientific Expeditions to Antarctica. In this provides detailed information on the basic design criteria for the PC controlled shipborne acoustic sounder and the studies over the ocean. User-friendly software for the system has been developed as to display the dynamic features of the atmosphere, in colour on SVGA monitor and to print them on a B&W dot matrix printer.

Status: Completed

Purpose: Acoustic sounding is an important technique to probe the Atmospheric Boundary Layer (ABL) on round-the-clock basis. It is due to its effectiveness and simplicity, probing the ABL, that almost all the atmospheric science programmes all over the world, utilise acoustic sounding system, as an integral part of the probing systems. The technique has been developed to study the ABL over various terrains (hilly as well as flat), valleys, Antarctica, and even over the floating vessels. The ABL group at NPL has designed and developed various types of monostatic acoustic-sounders, including the one deployed at Maitri, Antarctica The group has to its credit transfer of technology of the equipment to a private company, and thus holds total grip on the hardware, software, and other associated problems.
