AB: We present results from a new radiosonde temperature dataset, Radiosonde Atmospheric Temperature Products for Assessing Climate ("RATPAC"). The data are based on soundings from 85 stations, adjusted for inhomogeneities through 1997 by John Lanzante, Steve Klein and Dian Seidel, and extended through 2004 using a first-difference procedure. Time series for the globe, tropics and hemispheres show tropospheric warming over recent decades. We compare our results to those from other upper-air temperature datasets and assess uncertainties arising from the limited spatial coverage of the station network and from the methods used to produce the dataset.
