Narrative:
Takeoff minimums for runway 3L are 600/600/600 ft for approach, midfield, rollout RVR's respectively. ATIS reported RVR 3000 variable 700 ft. At beginning of taxi, RVR's were reported as 2000/700/700 ft. During taxi mid and rollout RVR varied considerably. Last heard RVR report prior to takeoff clearance was 3000/700/600 ft as I recall. After liftoff in response to another aircraft's question, the mid and/or rollout RVR was reported as 500 ft. I may have taken off with 1 or more RVR's less than required.
