Meteorological parameters and water balance components of Priyadarshini Lake at the Schirmacher Oasis, East Antarctica
The meteorological parameters and water balance components of Priyadarshini Lake at Schirmacher Oasis, East Antarctica, were studied using meteorological data procured from the India Meteorological Department (IMD) weather station, Maitri and field observations in summer seasons of 2017–2018 and 201...
