Narrative:

While serving as the check captain on air carrier flight number widebody transport lax- sfo, the captain departed with WX below mins. WX at time of departure was touchdown 2000, mid zero, rollout 4000. During taxi, new ATIS reported 200 and 1/2 mi visibility. As the captain lined up on 25R the tower reported the new RVR and cleared the flight for departure. It all happened so fast that the aircraft was going through 80 KTS before I could say anything. I felt it was safer to allow the flight to continue than to tell them to reject. In sfo I gave the captain an unsatisfactory check and assumed command for the rest of the flight (sfo-anc). The captain has been given additional training on operations specifications, takeoff and landing mins and another line check.
