This report illustrates and quantifies the unanticipated large uncertainty and differences in tropospheric temperature analyses within current global operational forecast systems and historical re-analysis products. Results reveal that regional patterns of uncertainty in seasonally averaged and daily atmospheric upper-air temperature analyses are related to the irregular distribution of in situ and satellite observations. There is less uncertainty in analysed temperature where in situ radiosonde observations are plentiful, primarily over developed nations in the Northern Hemisphere, and more uncertainty over regions that are observed primarily by satellites with fewer in situ temperature obs..
