RS92 GRUAN Data Product (v2) - Tateno 2009

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GRUAN数据产品文件基于维萨拉（Vaisala）RS92型探空仪采集的温度、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）》的规范完成处理，相关规范细节可参见Immler等人2010年的研究文献。本文件严格遵循GRUAN的各项要求，其中尤为核心的是提供完整的不确定度分析。不确定度的计算严格依据《测量不确定度表示指南（Guide for expressing uncertainty in measurement, GUM2008）》中的建议执行。总不确定度由校准不确定度、修正项不确定度以及统计标准差的估算值综合评定得出。依据当前的科学认知对数据施加修正处理，以确保数据无系统偏差。
