In the Chart Supplement (A/FD) for CRQ/KCRQ, you will find RVR-T for runway 24.
I was wondering what 'T' stands for?

I was wondering what 'T' stands for?
From page 5-1-7, contractions in the AIM:
RVRT . . . . . . . . . RVR Touchdown
The full list is:
RVR . . . . . . . . . . Runway Visual Range
RVRM . . . . . . . . RVR Midpoint
RVRR . . . . . . . . . RVR Rollout
RVRT . . . . . . . . . RVR Touchdown
On some runways there are multiple RVR sensors and different points along the runway, and these are the names given to identify the different locations.
Runway Visual Range - Touchdown
From FAA 6560.10C
Touchdown RVR VSs are located 0 feet to 2,500 feet (0 meters to 750 meters) from the runway threshold, normally behind the instrument landing system (ILS) glide slope (G/S) antenna, precision approach path indicator (PAPI), visual approach slope indicator (VASI), or microwave landing system (MLS) elevation antenna (if applicable).
While the other answers are correct, the dash in RVR-T is missing.
An overhaul (Interagency Air Cartographic Committee) done to the AFD makes it hard to get the up-to-date legend unless you're willing to download the full 300 MB document.
But I managed to find just the guidelines: Chart Supplement IACC 8, dated 25 April 2016.
3.1.5.3.13.11
Runway Visual Range shall be shown as RVR appended with T for touchdown, M for midpoint, and R for rollout; e.g., RVR-TMR.
It's got the dash!
RVR-TMR
on the Chart Supplement of KMHR. Thanks for digging this information!
