RS92 GRUAN Data Product (v2) - Lindenberg 2012

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.本数据产品基于维萨拉RS92（Vaisala RS92）探空仪的温度、湿度、风速与气压观测数据，该批数据已按照Immler等人[2010]中所述的全球气候观测系统参考高空观测网（GCOS Reference Upper Air Network, GRUAN）的要求完成处理。本GRUAN数据产品文件严格符合GRUAN的相关规范，尤其体现在提供了完整的不确定度分析内容。该不确定度的计算依据《测量不确定度表示指南》（Guide for expressing uncertainty in measurement, GUM2008）中的建议开展。总不确定度通过对校准不确定度、修正项不确定度以及统计标准差的评估结果综合求取。已施加对应修正措施，使数据依据当前学术认知实现无偏处理。
