Re: realtime.txt
According to http://en.wikipedia.org/wiki/Humidex it has no units (but roughly corresponds to degrees Celsius).

Re: realtime.txt
True....
(note that humidex is a dimensionless number, but that the number indicates an approximate temperature in °C)
So the approximate temp in C converted to F makes that value mean something to a person who never uses C for temps?
Note that Humidex originated in Canada which is a metric country.
Other values make approximations are well.. DewPoint, Heat Index, Apparent Temp, etc..

Code: Select all
DewPoint 32.5 °F (0.3 °C)
Wind Chill 73.8 °F (23.2 °C)
Heat Index 75.7 °F (24.3 °C)
Humidex 70 °F (21.1 °C)
Apparent Temp 83.1 °F (28.4 °C)
Re: realtime.txt
But I guess you could provide it as an index (Non °C) value:
Code: Select all
Less than 29 : Little or no discomfort
30 to 34 : Noticeable discomfort
35 to 39 : Evident discomfort
40 to 45 : Intense discomfort; avoid exertion
Above 45 : Dangerous discomfort
Above 54 : Heat stroke probable

Re: realtime.txt
Yes - the idea is that it's just an index, unlike the other data, and as it was invented in Canada it uses degrees C to calculate it. It would be wrong to quote it with a degrees C unit, and even more wrong to provide a Fahrenheit equivalent.

Re: realtime.txt
What are the equivalent tags in Cumulus for these?steve wrote: 41 recent max gust
42 heat index
43 humidex
I see #heatindex exists...
I would assume #humidex (though it is not there yet)
What is the definition of recent max gust?

Re: realtime.txt
Yes, #humidex, as mentioned above, and documented in the Help. I have a bit of a nomenclature problem with 'gusts'. The gust in the realtime.txt file is the latest reading from the station, as shown in the 'latest' box on the display, and the tag is #wlatest. 'Recent max gust' is the peak gust in the last 10 minutes, shown as 'gust' on the display, and the tag is #wgust.

Re: realtime.txt
Hello,
I do not find the realtime.txtx file in my file cumulus ( 1.8.3 ),
is it because of my meteorological station(resort)?
Johann (sorry for my english)

Re: realtime.txt
It only appears if you have selected the 'realtime' setting in the internet settings. Also, if you're running Vista it may not be in the obvious place (see lots of discussion about this elsewhere on the forum).

Re: realtime.txt
I've been having fun modifying the web pages, including massaging Pinto's Ajax stuff, combining some of TNETWeather's PHP stuff and some of my older stuff into a single page. I have a couple of questions related to the realtime.txt format (I'm using Pinto's reference as a guide):
1) #bearing and #wdir: is that the bearing/direction of the latest wind reading (#wlatest) or the current average (#wspeed)?
2) For the average (#wspeed), WeatherLink specifically says "10-minute average". What mechanism is being used by Cumulus (hopefully not average since last reset, since that's kinda useless)?
Probably more later...
Brad.

Use 10 min average wind speed
Tick this to make Cumulus calculate and display a 10-minute average wind speed instead of using the value supplied by the station. Normally only useful for Oregon Scientific stations, as these stations supply an average wind speed based on the last few seconds only. Davis stations supply a 10-minute average.

Thanks, I'm cooking now.

Re: realtime.txt
Low priority request, only if you find yourself messing with realtime.txt for some other reason, I'd love to have the equivalents of <#rrateTM> and <#TrrateTM> and maybe <#Tbeaufort> added (though I think I can calculate/lookup the latter via javascript (once I figure out a string-to-number conversion).
And if you were *really* feeling generous, I wouldn't mind having a new <#wchillTM> and <#TwchillTM> (low windchill & time) *and* equivalents in realtime.txt. Oh, and maybe <#humidexTM> and <#ThumidexTM> (high humidex).
I'll stop now.
