Measurement differences between air temperature instruments used at H.J. Andrews meteorological stations

The PRIMET Horizontal Radiation Shield Comparison (PHRSC) experiment compares the difference between the air temperature measurements of a reference temperature sensor inside a fan aspirated radiation shield and temperature sensors located inside passively aspirated radiation shields including a cotton region shelter, Gill multi-plate shield, and a custom-fabricated model. Observed variables include air temperature, wind speed, and incoming and reflected solar radiation. Data was collected in the field between 2010 and 2017 at the Primary Meteorological Station (PRIMET) at H.J. Andrews Experimental Forest, located in Oregon’s Western Cascades (44.21, -122.26, elevation 430m).

PRIMET水平辐射屏蔽对比（PHRSC）实验对比了风扇抽吸式辐射屏蔽（fan aspirated radiation shield）内的参考温度传感器，与包含棉区防护罩（cotton region shelter）、吉尔多层屏蔽罩（Gill multi-plate shield）及定制加工模型（custom-fabricated model）在内的被动抽吸式辐射屏蔽（passively aspirated radiation shields）内的温度传感器所测得的气温差值。观测变量包括气温、风速、入射太阳辐射与反射太阳辐射。该实验的野外观测数据采集于2010年至2017年间，采集地点位于俄勒冈州西部喀斯喀特山脉的H.J.安德鲁斯实验森林内的PRIMET基准气象站（Primary Meteorological Station），其坐标为44.21, -122.26，海拔430米。
