Joint Observing System Simulation Experiment (JOSSE) Data set
at NASA/NCCS portal and NCAR
Updated in August 2016
The data set described in this manuscript contains the data required to conduct initial OSSEs. The data set includes existing observations from the 2005-2006 Nature Run period and these data are considered as control observations to study the impact of additional observations. These data are also useful for OSSE to evaluate data assimilation systems. A Nature Run on a low resolution regular grid for OSSE verification is also included.
The data set consists of (A) ECMWF Nature Run at low resolution pressure levels to verify OSSE experiments, (B) simulated and real observations for control experiments, and (C) cloud data for cloud evaluation.
The complete Nature Run at model resolution and additional data are posted on the NASA/NCCS portal. It is easier to view the data at NASA as the NCAR data are saved on tape, but it is easier to download large quantities of data from NCAR.
Data set names at NCAR are marked in green. Currently the data are saved in the HPSS archive. Individual files are viewable from the NASA/NCCS/portal. The URL locations at the NASA portal are indicated in purple.
