Why some of the instruments are placed outside the weather shack?

Some instruments are placed outside the weather shack to ensure accurate measurements of atmospheric conditions, such as temperature, humidity, wind speed, and precipitation, without interference from the building itself. This positioning helps to capture real-time environmental data that reflects the actual weather conditions. Additionally, placing instruments outside minimizes heat or humidity generated by the shack, which could skew results. Proper exposure to sunlight and airflow is also crucial for instruments like solar radiation sensors.
