MOBILE STEVENSON SCREEN

· Completed building on the 25th of July 2003 & began testing the same day.

· Test data was proved very precise with all data being recorded within 1.0°C for both Min & Max Temperatures.

· Out of 6 readings so far, only 1 proved to be more than 0.5°C different to my official weather station thermometer. I  used my  Micronta digital thermometer to record Min/Max test data. Mobile screen was placed about 1m from official screen.

FURTHER

· I recorded a Minimum Grass Temperature of -3.8°C on the 28th.
