I just pulled the METAR for KLAX. Why are they reporting an RVR value for runway 25L if visibility is 9 statute miles?

KLAX 281553Z 00000KT 9SM R25L/2400VP6000FT FEW012 FEW045 18/08 A3000 RMK AO2 SLP157 FU FEW012 FU FEW045 T01780083 $

    $\begingroup$ Because it's an automated system, so it follows a standard format... And it looks like it needs servicing. $\endgroup$

  • $\begingroup$ Thanks for the reply, but RVR is usually not reported at KLAX from what I've seen in the past. $\endgroup$

  • $\begingroup$ It's possible that when the "I need servicing" indicator is there, it may report everything by default in case one sensor is bad. $\endgroup$

  • $\begingroup$ RVR and visibility is not the same thing. Besides, in theory, the general visibility could be good, while the RVR for a specific runway could be bad due to a local fog patch etc. Depends on the placement of the sensors. $\endgroup$ Oct 28, 2019 at 17:44

It looks like that METAR was corrected to

KLAX 281553Z COR 00000KT 9SM FEW012 FEW045 18/08 A3000 RMK AO2 SLP157 FU FEW012 FU FEW045 T01780083 $

Note the COR for corrected. The corrected METAR does not include RVR.

Including a screen grab of aviationweather.gov in case they dont keep the info up for a long time.
