Wind and temperature are the focus of the research unfortunately, with slope a player, but clearly tends not to change at the same airport. Thanks nonetheless aero.
(If you're interested - looking at climate change data, and showing the changes with time in available payload on "critical" (short, usually around tourist destination) airports. Some places we're seeing temperatures climbing over ½°C/decade and mean headwinds dropping over 2kts per decade. Small numbers day-to-day, but cumulatively quite large over the life of an aeroplane like the Dash-8 or 737 in terms of average useable payload , or alternatively shortest useable runway at MTOW.)
Anyhow Piece is a scholar and a gentleman who sent me the G400 planning charts, which I'm about to start having fun with.
