What role does terrain play in the effectiveness of RAWS installations?

Terrain plays a crucial role in the effectiveness of RAWS (Remote Automated Weather Stations) installations, particularly in how it impacts data accuracy due to variable weather conditions. Different types of terrain, such as mountains, valleys, or open plains, can create unique microclimates that may not accurately reflect broader weather patterns. For instance, a RAWS installation located in a valley may record different temperature and humidity levels compared to a station situated on a nearby mountaintop, even if they are close in distance.

Variability in terrain can also lead to challenges in data collection, as certain geographical features may obstruct wind flow or create localized weather phenomena, such as rain shadows. This means that the data collected could skew the understanding of weather conditions for a larger area, affecting decision-making for operations that rely on accurate weather monitoring. Consequently, the effectiveness of RAWS installations is heavily dependent on the surrounding terrain, which directly correlates with the precision of the data they provide.
