Orban Zsombor returns back safe and sound despite a mishap due to gale force winds after exploring a caldera situated in Bolivia (near the border of Chile) to find the largest daily temperature amplitude in the world.
The mountain named “Aguita Brava” is a location marked only on good topographical maps. The barren volcano is close to 5500 meters high with a crater of around 800 meters wide and 80 meters (260 ft) deep. The bottom of the caldera is situated at 5320 meters (17454 ft) above sea level. A perfect location for his research. GPS: -22.512, -67.796
The temperature inversion in the crater basin is so strong that on this day with still air and no clouds the air temperature rises from -35 degrees Celsius at ground level to -26.6 as measured in the MeteoShield Professional only 1.7 meters above ground.
The maximum temperature of the day was only +4 degrees Celsius but felt much warmer in the sun and thin air. The maximum daily fluctuation at this high altitude came to be a staggering 30.6 degrees Celsius (55.1 degrees Fahrenheit).
On the second day of measurements, gale force winds came in.... more details can be found on Orban's blog at the following link: http://weatherman.opofa.com/2018/07/12/aguita-brava-volcano-mars-on-earth-part-2/
