I am with the atmospheric transport group at the DOE's Savannah River Technology Center in Aiken, SC. We are running the NCEP ETA model at the Savannah River Site to provide local weather forecasts and transport predictions for emergency repsonse. We would like to apply for an associate membership in Unidata so that we can obtain the Gempak software. Gempak would be used for display of ETA output. If it is not possible to obtain Gempak through Unidata, can you suggest another source? Thank you for considering this request. Lance O'Steen
