During the Trace-P experiment we will be providing forecasts of a variety of trace species. The operational chemical weather forecasting system is based on 3-D on-line regional scale chemical transport model fully coupled with RAMS (Regional Atmospheric Modeling System). This system consists of several important components: i) operational global forecast data set access to NCEP (and JMA); ii) RAMS weather forecast for 72 hours based on the NCEP & JMA data as a lateral boundary conditions; iii) On-line chemical transport calculation of important chemical tracers; and iv) post-processing of  "chemical weather forecast" results with 2/3-D graphics into the WWW-page.

				Forecasting Domain

Three-dimensional fields for the domain shown and extending up to 15 km will be provided to support field operations. The primary products will be 2-dimensional images and quick-time movies showing main features of flow field and tracer distributions. These will be available over the web. In addition vis5d files will be downloaded in the field for additional analysis related to flight planning as well as quick-look analysis while still in the field. Further details are available at the websites listed below.

Additional Information:

• data volume: 30 MB per day
• modes of data transfer to the field: the basic information will be provided via our internet website; vis5d files will require download from our website
• device requirements: our vis5d files could be made also in CAVE display format;  color printer is needed
• field time when data sent to field: first level tracer products available at 9 am local time; additional products by 3 pm LT
• hours required to process data in the field (from download to discussion-ready): minimum time 2 hours
• name(s) of person in field who will handle your data: Greg Carmichael & Jim Yienger
• website URL if Internet download: ; http://www.cgrer.uiowa.edu/people/carmichael/ACESS/index.html & ; http://www.riam.kyushu-u.ac.jp/taikai
• equipment needed in the field: color printer, FAX
