| Joint OSSE is the international effort for collaborative OSSEs, where many centers share the same Nature Runs (NRs) to conduct OSSEs with different data assimilation systems. Verification of the NR and simulation of observations consumes a significant amount of resources. If the same NRs are used the results can be compared and the performance of reliable OSSEs will be faster. |

Produced by ECMWF in 2018 and Distributed from CIRA The 9-km ECMWF Cubic Octahedral (O1280) grid Nature Run (ECO1280) created by ECMWF and hosted by CIRA/CSU is a single uninterrupted 14-month (10248-h) long forecast made with a circa 2016 version (IFS cycle 43r1) of the operational global deterministic ECMWF atmospheric forecast model. |

The GEOS-5 Nature Run (Ganymed release) is a 2-year global, non-hydrostatic mesoscale simulation for the period 2005-2006. In addition to standard meteorological parameters (wind, temperature, moisture, surface pressure), this simulation includes 15 aerosol tracers (dust, seasalt, sulfate, black and organic carbon), O3, CO and CO2. This model simulation is driven by prescribed sea-surface temperature and sea-ice, daily volcanic and biomass burning emissions, as well as high-resolution inventories of anthropogenic sources. |
