We report the deployment of a new 3-laser photo-acoustic instrument in the Aerosol Observing System at the ARM SGP site in 2009. We compare our measurements of absorption and scattering with collocated independent measurements made with a PSAP and a nephelometer, respectively. We find relatively good agreement between the two observational periods, made during relatively clean periods. We also share the challenges and opportunities of adding new instruments and measurement capabilities at any ARM sites. These will be valuable to facilitate the operation and mentoring of new ARRA-funded equipment that is being added in the new integrated ASR program.
