Water vapour profiles from WAVAS SAtellite component in HARmonized format (WAVAS_SAHAR) - Version 2

This is the Version 2 of databank of satellite vertical profiles of the water vapour, that have participated in SPARC WAVAS assessment, in a harmonized format, WAVAS_SAHAR. All vertically-resolved satellite measurements of the tropospheric and stratospheric water vapour in the time period between 1984 and 2018 are included. The databank consists of water vapour profiles retrieved from each instrument, which are screened for invalid data according to recommendations of instruments’ teams, then transformed into a common unit and interpolated on a common grid. The data versions included are those existing at the moment of WAVAS exercise, hence not always the most recent at the time of publishing. The only difference of version 2 of the databank to the initial version of WAVAS-SAHAR is the MLS entry on ALT grid : in the version 2 the regridding was performed using the geometrical altitudes from Derived Meteorological Products (DMPs) for MLS profiles.

本数据集为采用统一格式WAVAS_SAHAR的卫星水汽垂直廓线数据库第二版，其所收录的数据均参与了SPARC WAVAS评估。本数据库涵盖1984年至2018年间所有对流层与平流层水汽的垂直分辨率卫星观测数据。该数据库包含各仪器反演得到的水汽垂直廓线：所有数据均依据对应仪器团队的建议剔除无效值，随后统一转换为标准单位，并在通用网格上完成插值处理。本数据库收录的数据版本均为WAVAS评估工作开展时已存在的版本，因此未必是发布时的最新版本。本数据库第二版与WAVAS-SAHAR初始版本的唯一差异，在于ALT网格下的微波临边探测器（Microwave Limb Sounder，MLS）数据条目：第二版中针对MLS廓线的重网格化处理，采用了派生气象产品（Derived Meteorological Products，DMPs）提供的几何高度。
