Talk:Rain gauge

message: This Was a very poor article- 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)
replies: text: Yes, the 6 inch diameter cylinder will hold 9 times the volume of the 2 inch diameter cylinder at the same height. However the larger cylinder will also collect 9 times the volume of rain, since it has a larger area for collection (see Tashiro's comment above). The result is both cylinders left in a rain storm would fill to approximately the same height as each other. There could very well be a standard rain gauge diameter but it wouldn't make a big difference to the rainfall reading. This idea might need to be in the article? -SmokeySteve (talk) 10:11, 14 April 2009 (UTC)
thread_title:  Some questions I had weren't addressed 

message: - 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?

thread_title:  format of the article 

message: 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)
replies: text: 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)
replies: text: 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)
replies: text: 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.

replies: text: I created a disambiguation page called Precipitation gage recently. It links to various ways to measure different types of precipitation. There's no reason IMHO to move rain gauge anywhere. Guy1890 (talk) 22:51, 8 February 2013 (UTC)

message: 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.

thread_title:  What is up with this? 

message: *The first known records of rainfalls were kept by the Ancient Greeks about 500 B.C. This was followed 100 years later by people in India using bowls to record the rainfall. The readings from these were correlated against expected growth, and used as a basis for land taxes. 
*In the Arthashastra, used for example in Magadha, precise standards were set as to grain production. Each of the state storehouses were equipped with a standardised rain gauge to classify land for taxation purposes.

thread_title:  How to Use and Measure a Rain Gauge 

message: The article says: "measure the amount of liquid precipitation over a set period of time".
Often in weather and news reports precipitation is reported as mm, no time period is given. I assume there is a standard time interval used. What is the standard time period used? Personally I feel meter per second makes more sense as a unit, any reason why that isn't used?85.230.137.5 (talk) 06:39, 2 January 2012 (UTC)
replies: text: We measure it every 6 hours. The reports may be talking about 24 hour periods if the are talking about a forecast. The reason that metre per second isn't used is because you will never see that much rain. Look at Rain#Wettest known locations. The most rain in a 12 hour period is 53 in/1,346 mm. In other words 1.3 m in 12 hours, nowhere near enough to give a metre per second use. By the way, if you were wondering, and I know I was, the 1,346 mm in 12 hours works out to 112.2 mm per hour, 1.9 mm per minute and 0.03 mm per second. CambridgeBayWeather (talk) 08:30, 2 January 2012 (UTC)
replies: text: Thanks for the answer! Maybe not meter per second but perhaps mm per hour (or day) instead of just mm would be less ambigous I think? 85.230.137.5 (talk) 11:48, 3 January 2012 (UTC)
replies: text: Depends on the gage.  In the United States, the heated tipping bucket and weighing precipitation gages used by ASOS are reported on an hourly basis in METAR reports.  Summary reports are generated in the 3-hour, 6-hour and 24-hour synoptic METAR reports.  Fischer-Porter weighing gages report in 15-minute intervals, but many of these are not transmitted in real-time.  Standard rain gages at NWS offices are generally read every 6 hours at the synoptic times.  For volunteer cooperative observers, their standard rain gages are usually read once a day.  Some agencies place collecting gages in the field which may only be read once a month or even once a year! Famartin (talk) 12:27, 3 January 2012 (UTC)
