I added some rain gauge pictures. Changed an Americianism. to reflect a more world view. Added discriptions of standard rain gauge and tipping bucket. The two discriptions I gave apply to rain gauges in Canada and they may be different in other parts of the world.

[edit] Some questions I had weren't addressed
I was thinking of making a rain gauge and came here. The history and comparison of official instruments is interesting, but leaves some questions unanswered.
- What is the diameter of an official collector? - What is the diameter of the measuring tube? - What is the weight threshold for tipping gauges? - What is the relationship between volume/collector area and the official precipitation depth?
Clearly, differences in any of these would result in different measurements.
These questions are most logically addressed here - I just don't have the answers (and am having trouble finding them).
- There appears to be no manual for the regular rain guage. I get about 11 cm diameter for the outer funnel and 3.5 cm for the diameter of the inner tube. These are for Canadian standard rain guage. As for the tipping bucket the manual does not say anything about the weight. However, it tips on ever .2 mm of rain, so whatever .2 mm weighs would be the threshold. Of course one thing to remember is that of the two types the tipping is less accurate and harder to make. Good luck. CambridgeBayWeather (Talk) 20:30, 25 February 2006 (UTC)
[edit] Questions re measurements
- What about Pts or points or rain...1/100th of an inch (or 25.4mm) correct? - Is 1mm of rain a standard over a certain area? e.g. 1mm over 1sq metre? Or can it be over any area? Zorruno 04:05, 13 March 2006 (UTC)
[edit] Wrong image of the so-called "1st" rain gauge from Korea
The image shown in the article depicted as the "first" rain gauge is not from Korea, but from China. There is a clear description in Chinese language on the artifact surface (on the left) which indicates the year and date of Chinese Qing dynasty. Whoever posts this image, please remove it or make a correction.
Koreans used Chinese writings until the 1400s when King Sejong and his scholars made the Korean alphabet. The writings do not say anything about Qing Dynasty. Please, whoever this user is, don't contribute wrong infos to begin or invigorate discrepancies and doubts.

There is no challenge in regards to the origin of rain gauge; Koreans are the pioneers in this area. However, the discrepancy is in the photo itself. The Chinese characters on the right side of the artifact indicate the year of Ching (or Qing 清) (Emperor year Name 年號: 乾隆; Dynasty period name 廟號: 高宗). 乾隆 was one of the well-known emperors in Qing period in China ruling from 1736 to 1795. Please verify these Chinese characters carefully with qualified historians and linguists, if you remain doubtful.
I'm sorry. The title "so-called" put me in aggressive manner. I thought the person who posted this controversy was an editor with some grudge or ill will against Koreans. Let me verify the source. (Wikimachine 01:01, 15 August 2006 (UTC))
- On google search of "측우시" or Cheok Woo Gi, the 1st rain gauge[1], 4 of these (you could search for more) showed the exact same wordings for the character.
- And I have some background knowledge in Chinese characters, so I am not talking expert about something I don't know.

[edit] format of the article
this article is awkward because introduction is about 1/3 of the article. I think that introduction needs to be short and the rest of the article should give more infos. (Wikimachine 20:01, 10 August 2006 (UTC))
[edit] Move to "Precipitation gauge"
My reasons to suggest a move from "rain gauge" to "precipitation gauge" is simple: rain is a subset of precipitation, but not the other way around. This article can be more general by a rename. A precipitation gauge (e.g., T200-B) can measure all forms of precipitation. Certainly, the majority of this article is about rain, however the suggestion of the article title neglects other forms of precipitation and their measurement. Post your comments below. +mwtoews 20:35, 13 September 2006 (UTC)
- These are three different things, A rain gauge, a snow gauge and a precipitation gauge. Part of the problem with rain guage was the first sentence which said that they collected solid precipitation and I changed that. We never use the rain gauge to collect snow. We have a T200 type here as well. I think that the three types should each have their own article. CambridgeBayWeather (Talk) 22:15, 13 September 2006 (UTC)
- I'm a mergist, so naturally, I'd suggest that all of the precipitation gauges can be described, and contrasted in one article. After all, there is overlap between "snow gauges" and "rain gauges", since something like a T200 measures anything that falls into it, whether it is rain, snow or frogs. The other option is to make a precipitation gauge article to give an overview of the various gauges. This article could also compare and contrast their limitations and measurement methods, and have links to the specific gauges with enough content to warrant their own article (such as tipping bucket rain gauge and snow gauge). +mwtoews 23:30, 13 September 2006 (UTC)
- I would suggest that you have Precipitation gauge with a general overview but then in turn have Rain guage and Snow gauge as a tipping bucket is just one type of rain gauge. Both the snow and rain gauge pages could have a header to direct people to the precipitation gauge page for a general overview. We need a picture of the T200 type and I'll try and get one tomorrow.

[edit] World's First Rain Gauge
It may be that the Greeks or some other civilizations have used bowls, etc. to measure rain gauges, but it is undisputed that Jang Yeongsil made the world's first rain gauge as meteorologists would say. Standardized measuring device that was adopted nationwide under government program. Plus, I'm not making this up from my opinion that Korea was the 1st. See the reference sources.
