The ARM Best Estimate Atmospheric Measurements (ARMBEATM) value-added product (VAP) provides a best estimate of several selected atmospheric state profiles and surface quantities observed by the ARM Facility. - The surface sensible and latent heat fluxes are from the Bulk Aerodynamic Energy Balance Bowen Ratio (BAEBBR) VAP and from the Quality Controlled Eddy Correlation Flux (QCECOR) VAP. -The large-scale atmospheric state variables are from the balloon-borne sounding system (SONDE), and the relative humidity data are from the Microwave Radiometer-Scaled Sonde Profiles VAP (where available), which scales the moisture profiles to match the microwave radiometer's total precipitable water vapor. -The surface precipitation, temperature, relative humidity, and horizontal winds are from the surface meteorological observational stations (SMOS) or ARM Standard Meteorological Instrumentation at Surface (MET) instruments. -To complement the sounding data, NWP analysis data are also included in the file for the SGP C1 site. The NWP analysis data are from the NOAA Rapid Update Cycle analysis.

大气辐射测量（Atmospheric Radiation Measurement, ARM）最佳估算大气测量（ARMBEATM）增值产品（VAP）依托ARM观测设施的观测数据，为若干精选大气状态廓线与地表参量提供最优估算值。
- 地表感热通量与潜热通量源自块体空气动力学能量平衡鲍恩比（Bulk Aerodynamic Energy Balance Bowen Ratio, BAEBBR）VAP以及质量控制涡度相关通量（Quality Controlled Eddy Correlation Flux, QCECOR）VAP。
- 大尺度大气状态变量取自气球探空系统（balloon-borne sounding system, SONDE）；相对湿度数据则来自微波辐射计定标探空廓线VAP（若可用），该产品会将水汽廓线缩放至匹配微波辐射计测得的总可降水量。
- 地表降水、气温、相对湿度与水平风场数据取自地面气象观测站（surface meteorological observational stations, SMOS）或ARM地面标准气象仪器（ARM Standard Meteorological Instrumentation at Surface, MET）。
- 为补充探空数据，SGP C1站点的数据文件中还包含数值天气预报（Numerical Weather Prediction, NWP）分析场数据，此类数据源自美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）快速更新循环分析产品。
