Do you land?
Of course I will; but I live in EASA-land where all I need is visual ref with one of about 11 items.
Is there a visibility requirement for CAT I approaches? Yes. And that visibility is measured by very smart people on the ground and then reported to the pilots.
Is the pilot expected to measure/assess such visibility once he is at MDH/DA? No. He has no idea how to do it, we don't trust him to do it accurately, and he doesn't have the time:need to focus on the landing.
Is the pilot entitled to a go-around after assessing he does not have the required visibility if the runway is in sight? Well, you should always feel free for a go-around whenever necessary, so I'll answer yes. Especially if you feel you have a poor visual contact. Depending on airline you might have to explain it, though... and the chief pilot might not buy it.
