FY 1993 Activities and Accomplishments and 

 FY 1994 Plans 



Network Access 



NOAA's pilot Internet Network Information Center has 

 begun to provide assistance in using the Internet, net- 

 work management for connected NOAA facilities, mail 

 and other server capabilities, and protected access to 

 selected NOAA operational data sets, such as NMC 

 model output data. 



In FY 1994, at least 10 more NOAA computational and 

 data archiving facilities will be connected to the Internet, 

 and connection bandwidth will be increased. 



Global Atmosphere and Global Ocean Modeling 



Over the past two years, NOAA's Geophysical Fluid 

 Dynamics Laboratory (GFDL) has begun redesigning its 

 most important atmospheric and oceanic models to 

 make them modular and parallel in design. This activity 

 includes a collaborative effort by GFDL with DOE/Los 

 Alamos National Laboratory (LANL) scientists that has 

 led to the successful design of a model shell version of 

 the GFDL Modular Ocean Model (MOM) to a form that is 

 amenable to highly parallel computers and that main- 

 tains its modular coding structure. High resolution 

 experiments using this new code were performed on the 

 1,024-node Thinking Machines CM-5 at LANL. 



GFDL's complete SKYHI global atmospheric grid-point 

 model, which is used to study climate, middle atmo- 

 sphere dynamics, and atmospheric ozone, has been 

 redesigned for parallel execution and ported to the LANL 

 CM-5, as part of the GFDL-LANL collaboration. 



The GFDL radiation physics package, which is a critical 

 part of all GFDL atmospheric climate models, was 

 redesigned to a modular form that is suited to highly par- 

 allel computer systems. 



In FY 1994, high resolution atmospheric modeling exper- 

 iments using a simplified-physics version of a parallel 

 atmospheric grid model will be performed to test model 

 sensitivity to grid resolution.
