NWA NEWSLETTER No. 06 –06 June 2006 operational meteorology, I can assure you that your PRESIDENT’S MESSAGE individual professional areas of interest and expertise were and continue to be well represented on the Council. by Dave Knapp I believe the Council departed Dallas with a renewed vigor What do you get when you put 20 people with a to make the right things happen to keep the momentum variety of operational meteorological backgrounds, and progress going in the coming months. All agreed that experiences, and interests, with different personalities and past NWA leadership has brought the organization to a perspectives, in a room for two days to discuss the point where we are on the verge of potentially significant current status and future of the NWA? Well, you get a growth in membership and influence in the operational fine group of professionals, most of them elected by you, meteorology community. The Council is leading the way who are dedicated to the best interests of the NWA. For down this exciting path in the coming months, and I look two very productive days, June 8-9, the NWA forward to reporting on some specific initiatives and Council met in Dallas for a midyear meeting. As I changes for the future at the Annual Meeting in Cleveland, reminded the Council at the start of the meeting, the all designed to keep the NWA relevant and prominent now published position description for NWA Council members and in the future. (see Web site: www.nwas.org/nwa_pd.pdf) reads, On the topic of NWA advocacy, prior to the midyear “Members of the Council are the Directors of the Council meeting, we worked with the Remote Sensing Association,” responsible for “general oversight for the Committee to put the finishing touches on a letter of association.” With that as our guide, we jumped right in support advocating the inclusion of a Microwave Sensor to address many topics that are important to the on an upcoming GOES platform. You have had an leadership and general membership this year. Discussion opportunity to participate in this process, and the Remote was often spirited, occasionally intense, and overall very Sensing Committee has appreciated your feedback in fruitful.

A more stable pointing Eta model with the NCEP North American Mesoscale platform on GOES-13 will allow NOAA to deliver improved (NAM) Weather Research and Forecasting (WRF) data to weather forecasters from the visible/infrared Model. The NCEP Eta model has been the workhorse imager and sounder. The satellite also carries an short-range forecast model used for forecast guidance expanded suite of instruments for monitoring the solar over the United States for more than a decade. It is being environment. A dedicated transponder on GOES-13 will replaced by the NCEP Nonhydrostatic Mesoscale Model support the Emergency Manager’s Weather Information (NMM), and its analysis is being replaced by the Gridpoint Network (EMWIN) service. GOES-13 also marks the Statistical Interpolation (GSI).
