NCEP OUTPUT AT INTERNATIONAL CEOP MOLTS SITES

(As of 01 December 2002)

NCEP has implemented routine output from the International CEOP MOLTS sites within its operational Global Forecast System (GFS) in two phases thus far to date (17 December 2002), as follows:

Phase I: (01 July 2002)

Thirty-six MOLTS sites (and their routine ftp transfer to NCAR) were implemented on 01 July 2002 in the then T170/L42 NCEP Global Forecast System (GFS).

Temporal Resolution: 3-hourly Forecast Length: 15 days Vertical Resolution*: 42 sigma layers

*(30 m thick layer 1, 10 layers below 850 hPa, 10 layers above 100 hPa)

Phase II: (01 December 2002)

-- added several new MOLTS sites (41 total stations) -- from new higher resolution, T254/L64 Global Model (as of 29 Oct 02)

Temporal Resolution: 3-hourly Forecast Length: 15 days Vertical Resolution*: 64 sigma layers

*(20 m thick layer 1, 13 layers below 850 hPa, 24 layers above 100 hPa)

Following 1) the CEOP Workshop of Sep 2002 (which led to the addition of several more MOLTS sites) and 2) the increase in NCEP global model resolution from T170/L42 to T254/L64 on 29 Oct 2002, NCEP implemented the following 41-site MOLTS station list on 01 Dec 2002:
