At Bison Engineering, we have been building and operating meteorological towers since 1980. We offer complete turnkey monitoring systems, or any service listed below. We construct, operate and report on meteorological stations that meet all EPA regulatory requirements, including PSD Pre-Monitoring Guidelines, to collect data suitable for any purpose, including permitting and regulatory dispersion modeling. Bison has constructed scores of meteorological towers, including 10-foot tripod portables, fixed 10-meter (the standard for modeling), 20-meter and 30-meter towers. Taller towers are available upon request.
