Cumulus Support

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

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..

But I guess you could provide it as an index (Non °C) value:

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.

What are the equivalent tags in Cumulus for these?

I see #heatindex exists...

I would assume #humidex (though it is not there yet)

What is the definition of recent max gust?

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.

so, can I keep this as a reference

Looks correct from a quick scan.

thanks

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)

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).

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...

The latest.

From the help file:

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.

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.

Brad.
