Evaluation of NOAA's Stratospheric Sounding Unit Climate Data Record

Recent recalibration of the Stratospheric Sounding Unit (SSU) temperature data record by NOAA/NESDIS/STAR has resulted in a quality climate data record (CDR) usable for climate studies. Corrections include: cell pressure drift, variable CO2 in the atmosphere, orbital drift, and limb correction. We use this STAR SSU CDR to compare against Nash's SSU climatology, previously, the only SSU climatology in existence. We will present comparisons of anomalies and trends from the Nash SSU data set and the new STAR SSU CDR. Comparisons with rocketsonde and lidar temperature observations will also be presented.
