Just another update. I’ve been looking at the data for quite some time now.
This fall raised new concerns about how good my thermometer is functioning.
I added a fan to the thermo/hydro housing a few weeks ago and I think that has really paid off in quality of data.
Rarely am I getting emails from CWOP these days on temp/dew point variances.
I’ve come to accept that my temps are just a bit higher than the closest surrounding area sensors as they’re very near the river.
The humidity is still lower than others during a rain but I now believe that is entirely due to the sensor’s location in a sheltered spot. If it were out in the open where the ground was wet, I’m sure it would peg out at 96%.
Again, everything goes back to careful planning of the sensors. I highly recommend adding a fan even if you’re getting good readings. It makes a big difference on days with no wind. I took a 12v computer fan and wired it up, but you can just as easily add a solar-powered fan for a few dollars.
