Comments on 'Global and Regional Comparison of Daily 2-m and 1000-hPa Maximum and Minimum Temperatures in Three Global Reanalyses'

摘要

Pitman and Perkins claimed that instantaneous 2-m air temperatures from different reanalysis products largely disagree over widespread regions of the globe and that, because of their much smaller differences, temperatures at 1000 hPa should be preferably used. This comment shows that this claim is based on erroneous results.
