ECMWF TOGA Global Advanced Operational Spectral Analysis, daily 1985-2010

The RDA maintains a collection of outputs from ECMWF's daily operational global numerical model. Dataset ds111.0 contains geopotential, temperature, wind, and moisture fields on constant pressure levels, starting in 1985. The horizontal resolution of the DSS archive is T106 spectral resolution in spherical harmonics, however, in later years, the model is actually run at a much higher resolution (T511 as of 2001). All fields are output four times per day at 00Z, 06Z, 12Z and 18Z. This dataset is updated twice a year.

The surface data can be found in ds111.1 [http://rda.ucar.edu/datasets/ds111.1/] and the supplemental fields including radiation, stress and flux terms are in ds111.3 [http://rda.ucar.edu/datasets/ds111.3/]. The model precipitation is archived in ds111.6 [http://rda.ucar.edu/datasets/ds111.6/]. The ECMWF operational model output on the 2.5 degree latitude-longitude grid can be found in ds111.2 [http://rda.ucar.edu/datasets/ds111.2/].

RDA持续维护着ECMWF每日运行的全局数值模式的输出集合。数据集ds111.0包含从1985年开始的常数压力层上的位势高度、温度、风速和湿度场。DSS存档的水平分辨率为T106球谐波谱分辨率，然而，在后来的年份中，该模型实际上运行在一个更高的分辨率上（自2001年起为T511）。所有字段每天输出四次，分别为00Z、06Z、12Z和18Z。此数据集每年更新两次。

地表数据可在ds111.1 [http://rda.ucar.edu/datasets/ds111.1/]中找到，而包括辐射、应力和通量项的补充字段则位于ds111.3 [http://rda.ucar.edu/datasets/ds111.3/]。模型降水量存档于ds111.6 [http://rda.ucar.edu/datasets/ds111.6/]。ECMWF的运行模型在2.5度经纬度网格上的输出可在ds111.2 [http://rda.ucar.edu/datasets/ds111.2/]中找到。
