Barral & Bixios meteorological flight
On July 27, 1850, two French agronomists, Jacques Alexandre Bixio and Jean Augustin Barral, made an ascent by a hydrogen-filled balloon from the garden of the Paris Observatory. They had seven objectives which included measuring the effect of altitude on the decrease of temperature, the variation in solar radiation, hygrometry, chemical analysis of air, the polarization of light by clouds and other optical phenomena. They were equipped with 2 barometers, 3 thermometers, a Walferdin minimum thermometer, a hydrometer and an Arago polariscope. They reached a height of 7016 metres where the temperature had fallen to -39 degrees F

EDITORS COMMENTS
This print captures a significant moment in the history of meteorology. On July 27,1850, two French agronomists, Jacques Alexandre Bixio and Jean Augustin Barral, embarked on a groundbreaking meteorological flight from the garden of the Paris Observatory. Equipped with an array of scientific instruments including barometers, thermometers, hydrometers, and even an Arago polariscope, they aimed to unravel the mysteries of our atmosphere. Ascending in a hydrogen-filled balloon, Bixio and Barral had seven objectives for their expedition. Among these were measuring how temperature decreases with altitude and studying variations in solar radiation. They also sought to analyze air composition chemically and explore optical phenomena such as polarization by clouds. Their daring ascent took them to an astonishing height of 7016 meters where temperatures plummeted to -39 degrees Fahrenheit. This remarkable achievement provided invaluable insights into atmospheric conditions at extreme altitudes. This image serves as a testament to the pioneering spirit that drove these agronomists to push boundaries in pursuit of knowledge about our planet's weather patterns. It stands as a reminder of their dedication and contribution to the field of meteorology—a legacy that continues to shape our understanding today.
