Effective with the 1200 UTC forecast cycle on February 8, 2005, MDL will be making a series of changes to the MOS products. These changes include new GFS BUFR products, new Eta BUFR products, increasing the frequency of issuance and stations available in the GFS-based coop MOS products, and new Eta marine text product. All of these changes are outlined below.

---

I. New GFS MOS BUFR products

We have redesigned the short-range GFS-based BUFR products to include updated elements and more stations. These products will contain GFS-based MOS forecasts for 6 to 84 hours from the 0000, 0600, 1200, and 1800 UTC model cycles. At some future date we will remove the current GFS-based BUFR products once customers have had a chance to modify their processes for the new products. The webpage http://www.nws.noaa.gov/mdl/synop/bufr.html has more details on our BUFR products, including WMO headers, and product content. Please see Technical Information Notice #04-53 for the official notification.

II. New Eta MOS BUFR products

We will begin issuing Eta-based MOS forecasts in BUFR format for 6 - 84 hours from the 0000 and 1200 UTC model cycles. The webpage http://www.nws.noaa.gov/mdl/synop/bufr.html has more details on our BUFR products, including WMO headers, and product content. Please see Technical Information Notice #04-52 for the official notification.

III. Changes to GFS-based MOS for cooperative observer stations

We will begin disseminating the short- and extended-range GFS MOS text products for cooperative observer stations over NOAAPORT and the SBN. We will be adding an extended-range text product at the 1200 UTC cycle, in addition to the current 0000 UTC product. A sample of the 12Z product is available here. The stations contained in all the coop text products will also change. We have added more sites to the message. A list of the 5656 sites available in the messages is available here. More details about the MOS guidance for cooperative observer sites is available at http://www.nws.noaa.gov/mdl/synop/coop.htm. Please see Technical Information Notice #04-54 for the official notification.

IV. New Eta-based text product for marine sites

We will begin producing a text product containing temperature, dew point temperature, wind speed and direction guidance from the 0000 and 1200 UTC cycles of the Eta model. More details about the MOS marine guidance are available at http://www.nws.noaa.gov/mdl/synop/marinedesc.htm . Please see Technical Information Notice #04-51 for the official notification.
