Are there any examples of these systems being used outdoors in similar climates?
Yes. Thermal camera temp checks are widely used around the world, both indoors and outdoors. They can be calibrated to take into account environmental and ambient temperatures, and the most accurate ones take measurements from around the subject's eyes.
In person, I've only seen them used in Singapore, Taiwan, and Korea. I've seen indoor setups where you walk under an array of cameras with monitors on either side showing realtime thermal imaging video. I've also seen several more temporary setups, which look more like just a camera on a tripod and an official monitoring the video. These portable systems are what I've seen used in outdoor shopping areas, security checkpoints, and outdoor concert venue entrance gates. I believe Disney uses a thermal temp check system in Shanghai.
