1. - almost any passive shield will do well in a breeze.
But they don't do equally well in a moderate breeze and strong sunshine - there are good and bad performers
You can find a lot of information on https://www.allmeteo.com/radiation-shield-comparisons/
Is there more information than just the graphs I can see on that page? I don't find the graphs alone very helpful because too much information is missing. A good trial report would do the following:
Monitor all the temperature sensors to be used in a single shield for a period of time to start with to ensure that they all read identically (or to measure/define any small offsets that might need to be applied to the experimental readings).
Then resite the sensors in however many shields are to be compared, logging temperature, mean wind speed and sunshine intensity over discrete periods (eg 5 or 10 minutes). And plot temperature _differences_ of eg test sensor/shield vs FARS against wind speed - that's the plot I'd like to see because it's the only way of telling for sure whether a new shield is any good or not.
As I say, I think this Barani shield (which IIRC we were looking at a year or so ago after the Madrid expo) is an interesting idea, but I'd like to see more compelling evidence that it provides real benefits.
