Canadian RVR

[JeanFrederik]

This is the format used for RVR in a Canadian METAR

R06/6000FT/D
R36/P6000FT/U
R24/1200V2600FT/N

The US/Canada RVR is already implemented and should be working normally. To get it to work you should add %rvr_grp% in the format at row 'rvr' and change %rvrminm% and %rvrmaxm% to %rvrminft% and %rvrmaxft% at 'rvr_grp'. In the strings there are optional _u, _n and _u_n endings to the strings. _u = unit is added at the end of the value, _n = in plain numeric (e.g "1000". Default functionality without _n parameter is {1000}). _u_n is both of those.

Great stuff, thank you

I noticed that RVR won't show if a value is below 1000FT. Could you look into it please?

[Sami Ylismäki]

I'll see about that

I didn't find any problem with the RVR values not showing and I tried a few different types of RVR. It'd be helpful if you'd include the METAR which caused problems, it would make it much easier to see what you see.
It could cause problems with RVR values below 1000ft if those are not preceeded by 0 as per the METAR decoding documentation.

I did find a problem where two types of rvrft strings had metric output.
