1smos (a0)

The surface meteorological observation system (SMOS) mostly uses conventional in situ sensors to obtain 1-minute, 30-minute, and 1440-minute (daily) averages of surface wind speed, wind direction, air temperature, relative humidity (RH), barometric pressure, and precipitation at the Central Facility and many of the extended facilities of ARM's Southern Great Plains (SGP) observatory. The SMOSs are not calibrated as systems. The sensors and the data logger (which includes the analog-to-digital converter, or A/D) are calibrated separately. All systems are installed using components that have a current calibration. SMOSs have not been installed at extended facilities located within about 10 km of existing surface meteorological stations, such as those of the Oklahoma Mesonet. These systems are used to create climatology for each particular location, and to verify the output of numerical weather forecast and other models. They are also used to "ground-truth" other remote-sensing equipment.

地面气象观测系统（surface meteorological observation system，简称SMOS）主要采用传统原位传感器，在ARM南大草原（Southern Great Plains，简称SGP）观测站的中央设施及众多扩展设施中，获取地面风速、风向、气温、相对湿度（RH）、气压和降水量的1分钟、30分钟及1440分钟（每日）平均值。SMOS系统并非作为整体进行校准，而是将传感器与数据记录仪（含模数转换器（analog-to-digital converter，即A/D））分开校准。所有系统的安装均采用经最新校准的组件。在距离现有地面气象站（如俄克拉荷马州Mesonet气象站网的站点）约10公里范围内的扩展设施中，未部署SMOS系统。这些系统用于为各特定地点构建气候学数据集，并验证数值天气预报及其他模型的输出结果；同时还可为其他遥感设备提供“地面实况”验证。
