I found the following links with a quick Google search plus the
Stevenson screen link which I had bookmarked some time ago.

The Weather Wunderground seems to be a pretty good sumary.

This made me wonder about sensor placement. I have had a number of
different wx stations and the instructions most provide for the
placement of the outdoor temperature sensor is to simply mount it on
the north side of the house just under the eaves. This kind of makes
sense as it will be away from direct sunlight but what about the heat
from the house?
How many do this and does it work for you? Do your temperature
readings match those or come very close to an "official" local temp
like at an airport.
Has anyone else noticed just how critical the placement of this sensor
really is? I have 2-3 outside sensors in different locations and they
all read differently, sometimes as much as a 4F delta. I made sure
they were all calibrated inside the house to read the same then
installed them outside. Once the sun goes down my readings stabilize
and my readings are within a degree of the "official" airport
temperatures. During the day, esp summer time the readings can be all
over the place.
I know enough to keep them out of the sun, away from objects that can
absorb & retain heat, off the ground at least 10' or so, not above
concrete, etc......and yet I see big differences. So my question is
where and how do people mount their temperature sensors?
Also does anyone know where and how the "official" temperature sensors
used by the NWS are mounted in places like airports?

I bought a Davis Weather Station for my wife, who is a Weatherbird,
seven years ago. As I recall, it was a six hundred dollar unit. In
the past seven years, the only maintenance I have performed on it is
remove a seed (from my neighbor’s tree) that blocks the flow of
moisture through its self-emptying range gauge. It has a solar panel
that recharges the unit’s rechargeable batteries. I have yet to
change them.
The unit is attached to a twelve-foot pole.
The installation instructions are a little vague on various points,
but that’s the only criticism I can make of this package. Not a cheap
station, but one my wife has been happy with, as the base unit sits
on a end table by her chair in our living room. She checks the base
station five or six times a day when she’s not monitoring the Weather
Channel or the ND DOT online.
