     The Arm Ocean project (AOP) is an extension of the DOE/ARM research effort in the Tropical Western Pacific Ocean (TWP). (See below.)

The Department of Energy's Atmospheric Radiation Measurement (ARM) Program is a key component of the Department's research strategy to address global climate change. The program is a direct continuation of DOE's decade-long effort to improve General Circulation Models (GCMs) and to provide reliable simulations of regional and long-term climatic change in response to increasing greenhouse gases. Three surface observation sites, collectively called the Cloud and Radiation Testbed (CART), have been established over the last five years. The sites are highly focussed observatories for the study of important atmospheric processes, particularly cloud/radiative forcing and feedback. Sites will operate over decade time scales. The ARM web site is located at http://www.arm.gov.

The Tropical Western Pacific Ocean (TWP)  (See http://www.twp.arm.gov)  locale lies roughly between 10 N and 15 S latitude and 120 E to approximately 160 W longitude, about the same area as North America. Geographically, this locale is characterized by the maritime continental area in the southwest portion and essentially open ocean in the northeast portion. Because of the large area, relative inaccessibility, and predominance of ocean, this locale suffers from a critical lack of climatological data from the ocean, the atmosphere, and the interface. Observational methods practiced here must be different than the methods used for the continental Oklahoma site.

    The choice of the TWP locale was dictated, in large part, by the ocean warm pool and the deep convection associated with it. The linkages between the ocean and the atmosphere are not well understood quantitatively. ARM will contribute to our knowledge of this region by carrying out high-quality observations over an extended period of time. In order to do so, however, we require: (a) long-term measurements of surface fluxes over the ocean; (b) simultaneous measurements of boundary-layer structure and cloud properties; and (c) spatially extended measurements of atmospheric properties.

     Research at BNL focuses on the important over-the-ocean measurement program within the TWP implementation strategy. However, the early phases of this program must deal primarily with instrumentation. The following tasks are presently underway:
