GLOBAL CLIMATE & WEATHER MODELING
  • GFS - see GFS R&D page
  • Joint OSSE- 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.
