+ | FOR EACH SUBMISSION: Put an entry into the htap wiki page [[modelupdates|Log file]], describing what has been submitted. This is also obligatory if changes or updates (even partial) to the original submission are made. We also request modellers to record on the wiki information on known bugs, or any other relevant information needed for analysis of the model results by others. | ||

In case of updates of files, the model version identifier should also contain information on the resubmission of model results. Additional files which do not change an earlier submission may contain the same version number as an older submission. Corrections and a model rerun should be accompanied by a new model version identifier. Old still valid files may be merged upon request with new data. Old versions of model submissions will be temporally moved to a separate directory by Met.No, and where possible, deleted after some time. An exception will be made for versions that have been used in publications. Modellers are responsible for communication of major updates to their models (e-mail and log-files, see below). Model analysers are responsible for frequently verifying changes in model submissions (e.g. before submitting a paper). | In case of updates of files, the model version identifier should also contain information on the resubmission of model results.
