Weather Instruments
2
Anemometer

• This is used to measure wind speed.

3
Thermometer

• This is used to measure temperature.
• Temperature is the kinetic energy of the atoms.

4
Psychrometer

• This gives a dry bulb and a wet bulb temperature
  that are then used to determine relative humidity
  and dewpoint

5
Psychrometer for Dewpoint
6
Psychrometer for Relative Humidity
7
Barometer

• This measures air pressure.
