RS92 GRUAN Data Product (v2) - Lindenberg 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RS92探空仪（Vaisala RS92 radiosonde）采集的气温、湿度、风速与气压观测数据，且已按照全球气候观测系统参考高空观测网（GCOS Reference Upper Air Network, GRUAN）的相关要求完成处理，具体规范详见Immler等人[2010]的研究。本GRUAN数据产品文件完全符合GRUAN的规范要求，其中尤为突出的是提供了完整的不确定度分析内容。该不确定度依据《测量不确定度表示指南》[GUM2008]的建议方法进行计算，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综合评定。已对数据施加修正处理，以确保基于当前学术认知实现数据无偏性。
