| Notes: (1) Code figures 12 and 13 are intended in cases where code figures 0 and 2 may not be sufficient to indicate that significant post-processing has taken place on an intial analysis or forecast output. (2)Analysis increment represents analysis minus first guess (3)Initialized analysis increment represents initialized analysis minus analysis |
