Year of Polar Prediction in the South Hemisphere: Special Observing Period Radiosondes, 2018-2019.

This directory contains ASCII text radiosonde launch data files from participating Antarctic research stations/vessels as part of the Year of Polar Prediction-Southern Hemisphere Special Observing Period during the 2018-2019 austral summer. Data were acquired from the British Antarctic Survey (BAS) REference Antarctic Data for Environmental Research (READER): legacy.bas.ac.uk/met/READER/YOPP-SH/ Data were gathered at the following Antarctic research stations/research vessels: Aboa, Alguhas II, Almirante Maximano, Amundsen Scott, Casey, Concordia, Davis, Dome A, Dumont Durville, Ascudero, Fuji, Halley, Jang Bogo, King-Sejong, Macquarie, Marambio, Mario-Zuchelli, Mawson, McMurdo, Mirny, Neumayer, Polarstern, Princess Elizabeth, Rothera, RV Kronprins Haakon, Shirase, Syowa, WAIS, and Zhongshan.

Each file is named {research station}_YYYYMMDDHH.dat, where: - {research station}: research station from which the weather balloon was launched - YYYY: year - MM: month - DD: day - HH: hour Each file contains 8 columns of space-delimited data of the observations: - Time (UTC) - Pressure (hPa) - Height (meters above mean sea level) - Temperature (C) - Relative humidity (%) - Dewpoint (C) - Wind direction (degrees) - Wind speed (kts)
