I looked at the 2 still reporting stations last night ... the Davis and the 1400 ... and there was also a 3 degree spread in temps with the Ambient reading cooler.
That surprised me at night (or 1am EST). Are the temp sensors that different all day long?
Not that it would help at night, but I wonder if there is a way to improve the 1400s radiation shield around the temp sensor. I am noticing slight temp spikes on mine in direct morning sunlight compared to another 1400 about 1.83 miles away and an AcuRite 5 n 1 about .7 miles away. Both are lower than me in the morning by about 2 degrees. But both are poorly mounted.
- the other 1400: down in a hole of low elevation, in a cluster of trees, shaded almost all day. The wind would be way off. Temps might be ok by low elevation.
- the AcuRite is on a small lot surrounded by trees. it is below the tree tops by several feet, and is on the east side of the property so it too is not taking morning sun.
(both of these would have very poor wind and wind direction info and makes me wonder about WU's QC for wind and direction due to mount set ups)
My 1400 is 25ft off the ground mounted on the roof in a much more open area. The temp sensor is about 9 feet off the roof which is white metal.
But as to 1400 mods ...
1. would there be a way to modify the 1400s Anemometer for better resolution?
2. would it be possible to modify (paint, insulate, etc) or replace the radiation shield with a larger shield? I wounder if using one of the Ambient weather shields would improve unshaded temp readings and if you could get the larger sheild to fit onto the 1400 body
