~
Wet Bulb & Dry Bulb Thermometers - Purchased Bureau of Meteorology (BoM)
standard thermometers to test the |
accuracy of my thermometers. I will also be
able to compare relative humidity values to my hygrometers. |

Alterations |
|
|
|
~
On the 14th I moved my ferrite supressor to near my AWS rain gauge to see if
this can reduce my erronous data. |
This has so far proved unsuccessful. |

Light
Winds / Possible Erronous Data |
|
|
~
Throughout the last two thirds of Apr wind readings from my AWS have been
extremely low. At this stage I am not |
sure if this data is correct or if the
bearings in my anemometer are wearing. On the 28-29th I conducted a test with
my |
car anemometer to compare both max wind
gusts & total wind run, albeit from a much more sheltered location.
Results |
I feel were too close to indicate erronous
data. I will continue to monitor this situation closely. |
