TL;DR: The NCEP/NCAR 40-yr reanalysis uses a frozen state-of-the-art global data assimilation system and a database as complete as possible, except that the horizontal resolution is T62 (about 210 km) as discussed by the authors.

TL;DR: ERA-40 is a re-analysis of meteorological observations from September 1957 to August 2002 produced by the European Centre for Medium-Range Weather Forecasts (ECMWF) in collaboration with many institutions as mentioned in this paper.

TL;DR: The National Centers for Environmental Prediction (NCEP) and National Center for Atmospheric Research (NCAR) have cooperated in a project to produce a retroactive record of more than 50 years of global analyses of atmospheric fields in support of the needs of the research and climate monitoring communities as mentioned in this paper.

TL;DR: The Comprehensive Ocean-Atmosphere Data Set (COADS) as mentioned in this paper is the result of a cooperative project to collect global weather observations taken near the ocean surface since 1854, primarily from merchant ships, into a compact and easily used data set.

TL;DR: The first three zonal harmonic waves in the troposphere and lower half of the stratosphere in January are described by longterm monthly means and by monthly means for 7 single years as mentioned in this paper.
