This data is recorded using a wireless Davis Vantage Pro 1 with the datalogger and Weatherlink software. Presentation to web also uses Dreamweaver 8 and customisation features of Weather Display and Weather Display Live and the VirtualVP utility. The ISS ( rain gauge / temperature and humidity sensor ) is attached to the top of a fence, facing ESE. It is sited at 1.2m above loose soil, 4m away from the house. The anemometer is located separately, 4.5m above ground level and with the house obstructing much airflow from NE to E.
