41 Challenges Engagement of the NWP research community is a critical component to making contributions to the operational NWP capabilities NEMS is still under active development, so any decision to package a software release to the research community must be done with careful coordination between EMC and DTC A fully supported community software package requires considerable resources from DTC. Is this the best use of DTC resources?
