D. Hurst (NOAA/ESRL) – Monthly NOAA frost point hygrometer sondes launched year-round since 1980 to obtain profiles of water vapor, temperature, pressure, and winds from surface to ~26 km. An ECC ozonesonde is part of the payload when the NOAA FPH is launched.
P. Disterhoft (NOAA/ESRL) and B. Liley, M. Kotkamp, and R, McKenzie (NIWA) – Spectral UV irradiance measurements (285-450 nm) since June 1998. Three different NIWA double monochromators have been used at three sites in and around Boulder. The present instrument (UV5) has been in use since August 2001, and participated in the 2003 International UV Spectroradiometer Intercomparison at Table Mountain, CO. It is calibrated biannually with external reference lamps and weekly stability calibrations are conducted with an internal lamp. Data is archived since 2004.
