| Instrument Additions | |||||||||
| ~ 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. | |||||||||
| Instrument 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. | |||||||||
