RS92 GRUAN Data Product (v1) - Cabauw 2011

This product is based on Vaisala RS92 radiosonde measurements of temperature, humidity, wind and pressure that have been processed following the requirements of the GCOS Reference Upper Air Network (GRUAN) that were described in Immler et al. [2010]. The GRUAN data product file comply to the requirements of GRUAN in particular by providing a full uncertainty analysis. The uncertainty is calculated according to the recommendations of the “Guide for expressing uncertainty in measurement” [GUM2008]. The total uncertainty is assessed from estimates of the calibration uncertainty, the uncertainty of corrections and statistical standard deviations. Corrections are applied such that the data is bias free according to current knowledge.本数据集基于维萨拉（Vaisala）RS92型无线电探空仪（radiosonde）获取的气温、湿度、风速与气压观测数据，且已依照Immler等人[2010]所述的全球气候观测系统参考高空观测网（GCOS Reference Upper Air Network, GRUAN）相关要求完成处理。本GRUAN数据集文件通过提供完整的不确定性分析，尤其符合GRUAN的规范要求。不确定性的计算依据《测量不确定度表示指南》（"Guide for expressing uncertainty in measurement", GUM2008）的相关建议开展。总不确定度通过校准不确定度、修正项不确定度及统计标准差的估算值进行评定。已施加修正处理，使数据基于当前认知实现无偏。
