Re: Barograph ink and pen

Hi, Well, that barometer is a nice device. Its stated accuracy is 0.08 inches of mercury, which sounds excellent but sounds less so in millibars - +/- 2.7mb. Now 2.7Mb isn't bad. The old Met office MkII barometer (which was physically similar to the Proteus) had to be within 2.3 Mb at 1000, 950 and ...

Re: The Snowdon 5 inch copper rain gauge

On page ix of "British Rainfall" 1920, under the heading "Standardization of Rainfall Records" it states, in an excerpt from the "Meterological Magazine of July 1921" [yes, it appears to be time travelling into the future] that "The prototype of the approved...
