Wind Speed and Wind Direction are measured using conventional cup and vane techniques. All other measurements are housed in a multi-plate naturally aspirated radiation shield to reduce solar radiation errors.
The shield is constructed of a series of concentric white aluminum plates, which allow air to fl ow through the shield, while blocking direct solar rays.
The temperature sensor is a platinum RTD class 1/3B. Relative humidity is a based on our very accurate solid
state sensor designed for continuous exposure to adverse climates.
The barometric pressure sensor is a piezo-resistive device designed for robustness, high accuracy needs, as
well as long term stability.
