Unscientific update sky partly cloudy winds light, calm in am picking up to 7 to 10 mph. pro 72.8/99.4 fars 72.8/100.4 standard 73.2/100.6
Quote from: ValentineWeather on August 22, 2018, 05:55:17 PMThese are the best shields so for clean comparison only including best two. Granted, early, but are you gleaning that the stock fan is under performing compared to the a/c fan?

Did I read somewhere on this forum that the USGS uses the Standard MeteoShield?
Well I bought another transmitter and got it set up today. Running two 75's now one in the Meteoshield Pro (main station) and another in a Davis FARS (Extra Temp Station) with stock fan. Didn't get to do a lot of scientific comparing today but from what I could eyeball the Meteo Pro generally ran cooler. Will have to look at the highs when I get off work late tonight. Like the rest of you I really wish Davis would start supporting temp in tenths of a degree with their extra temp stations. Dont really see how this would be difficult.Ill also start supplying some graphs for comparison.

I'm using envoy8x even though old and never updated software it does the job, really couldn't live without. Supports 8 pro stations or combo of soil/leaf.

I guess I'll just have to make due with the decreased resolution for now.
Another day of no wind. [ You are not allowed to view attachments ]
Wind was sporadic yesterday for me. My FARS was .9 cooler on peak. When wind is up the Pro does slightly better. I think once the wind stops FARS is pulling cooler air off the grass is what's going on. I went outside when it was 90° and putting hand on lawn it's cooler than air temperature for sure. Put that same fars shield over hot sand results would be different even on calm days. I think bare ground would be better indication and grass causes artificial cooling. One of the reasons I'm running 1-2 degrees under airport. Nothing but sand and cactus everywhere mixed with prairie grass.
But he's asking about the 75, does that need it too?

FARS cooler by .4F.
