Installation of SODAR during eleventh Antarctic Expedition
Background:
The eleventh Antarctic Expedition was conducted by the Indian government from November 1991 to March 1992. The aim of the expedition was to establish a permanent research base in Antarctica, known as the Indian Antarctic Program.
Installation of SODAR:
During this expedition, the Indian scientists installed a SODAR (Sonic Detection And Ranging) instrument in Antarctica. SODAR is a remote sensing device that uses sound waves to measure atmospheric parameters such as wind speed, direction, and turbulence.
Importance of SODAR:
The installation of SODAR in Antarctica was significant for the following reasons:
1. To study the atmospheric conditions: The data collected by SODAR helps in the study of atmospheric conditions in Antarctica, which is critical for understanding global climate patterns.
2. To improve weather forecasting: The information provided by SODAR is useful in improving weather forecasting in remote regions like Antarctica, where weather conditions can be severe and unpredictable.
3. To monitor climate change: SODAR data can also be used to monitor the effects of climate change on the Antarctic environment.
Conclusion:
The installation of SODAR during the eleventh Antarctic Expedition was a significant milestone in India’s efforts to establish a permanent research base in Antarctica. The data collected by SODAR has contributed to our understanding of atmospheric conditions and climate patterns in Antarctica, and has helped in improving weather forecasting in the region.
