(*) On 19 (21 UTC) and 20 January 2010 (00 UTC) the stations 44221 Gandan Huryee and 44224 Tsetsen Uul (both
Mongolia) reported values of 1086.2 and 1086.6 hPa.
However, the stations are located at altitudes of 1,421 and 1,928 m above sea level,
and with temperatures of -44.5 and -42.7 ° C at the time of recording, a reduction of the air pressure to
sea level is subject to big errors and is inadmissible. Thus, these values do not represent valid world records.
On 13 September 2012, the World Meteorological Organization (WMO) invalidated the 90-year-old record from Libya.
