There is a new benchmark in barometric pressure sensors, according to Bosch Sensortec, which claims that its new sensing device can measure a barometric pressure fluctuation that’s equivalent to ...

They are unrelated, but the implication is that air at a temperature of 100 degrees at sea level, if it is dry, will have its temperature reduced to zero degrees at 18,500 feet because the temperature ...

This blog is a follow up to my previous post on world barometric pressure records. In this case the highest rather than the lowest such. This post completes my recent series on pressure records.

That’s a line from the WWII movie, with Gregory Peck talking to the crew of his B-17 bomber on a mission over Germany. The B-17 was a four-engine bomber that required the crew to wear oxygen masks at ...

OBSERVATIONS made by Pugh on Mount Everest in 1953 showed that the relationship between barometric pressure and altitude corresponded more closely with that of Zuntz, Loewy, Müller and Caspari 1 than ...
