Meteorological instrumentation rain gauge. In 1714, Gabriel Fahrenheit creates a reliable scale for measuring temperature with a mercury-type thermometer. In 1742, Anders Celsius, a Swedish astronomer, proposed the 'centigrade' temperature scale, the predecessor of the current Celsius scale. In 1783, the first hair hygrometer is demonstrated by Horace-Bénédict de Saussure. In 1806, Francis Beaufort introduced his system for classifying wind speeds. The April 1960 launch of the first successful weather satellite, TIROS-1, marked the beginning of the age where weather information became available globally. This was also used to measure the temperature of the surrounding air. A thermometer measures air temperature, or
Celsius 41.11 "Fahrenheit 9/11", as "well crafted" believing that, while Moore had angered the targets of his film he "went the extra mile, creatively, to do so". In contrast Kennicott described "Celsius 41.11" as "dull, lazy and inconsistent". "Celsius 41.11" was criticised for sharing some of what reviewers perceived to be the flaws of "Fahrenheit 9/11". For example, Desson Thomson of the "Washington Post" (although generally positive about "Celsius 41.11") said that in the case of both films "the spleen factor could poison small children". Writing in the "Milwaukee Journal Sentinel" Duane Dudek said, "as with "Fahrenheit 9/11", it's impossible to separate
