Airflow Characteristics of Commonly Used Temperature Radiation Shields

The air temperature radiation shield is a key component in air temperature measurement in weather station networks; however, it is widely recognized that significant errors in the measured air temperature exist due to insufficient airflow past the air temperature sensor housed inside the shield. This paper focuses on the airflow characteristics inside air temperature shields including the MAximum-Minimum Temperature System (MMTS), the Gill shields, and the Cotton Region Shelter (CRS).
