Transmission of Monthly Forecast products

The dissemination file name convention used for the transmission of Monthly Forecast products is described in Section 12. Four sets of dissemination files are generated, each containing data for a collection of data streams. Data stream indicators used for these products in dissemination file names are:

- `F' data stream ENFO (real-time atmospheric data)

- `H' data streams ENFH and ENHS (hindcast atmospheric data)

- `V' data stream WAEF (real-time wave data)

- `Z' data stream ENWH (hindcast wave data)

Monthly Forecast products are prepared separately from other dissemination products, and are transmitted as one file per forecast day, resulting in 33 files per a data set described above.

Monthly Forecast products which are requested using time step range (STEP=valu1-value2) are also stored in these daily dissemination files using end of the range step to determin corresponding forecast day. When determining forecast day, please note that 00 UTC of each day is taken as the first hour of that day. Real-time Monthly Forecast products are released for dissemination on Thursdays, starting at 22 UTC. Hindcast Monthly Forecast products are released for dissemination on Thursdays, starting at 10 UTC. Default transmission priority for these products is 90.
