Sun reflection over snow I can report very good results today. 750 W/m2 solar and seeing no temperature increase inside the shield. It's running a few tenths under the FARS. Very good news indeed, the new Pro shield design change with added black and plastic composition is looking like a winner. Prior testing I was seeing 2F+ over snow.
I would still like to see an extended period of full sun at least an hour-long of 0-3 mph at anemometer height and check for heat buildup inside the shield for conclusive evidence but with snow reflection, I'm seeing virtually no warming of the sensor inside the shield.
In general, the PRO runs cooler daytime by about 1/2 degree vs Davis FARS with wind speeds in 8+ mph range. Sometimes it gets as much as .8 tenths cooler as wind speeds increase.
Here is 1:35 pm snapshot 700 W/m2 solar over snow with a 4 mph wind speed less at shield itself I'm sure.
