TL;DR: ERA-Interim as discussed by the authors is the latest global atmospheric reanalysis produced by the European Centre for Medium-Range Weather Forecasts (ECMWF), which will extend back to the early part of the twentieth century.

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.
Journal ArticleDOI
ERA-20C: An Atmospheric Reanalysis of the Twentieth Century
Paul Poli,Hans Hersbach,Dick Dee,Paul Berrisford,Adrian Simmons,Frederic Vitart,Patrick Laloyaux,David G. H. Tan,Carole Peubey,Jean-Noël Thépaut,Yannick Trémolet,Elías Hólm,Massimo Bonavita,Lars Isaksen,Michael Fisher +14 more
TL;DR: The ERA-20C water cycle features stable precipitation minus evaporation global averages and no spurious jumps or trends as mentioned in this paper, and the assimilation of observations adds realism on synoptic time scales.
Evaluation of remotely sensed and modelled soil moisture products using global ground-based in situ observations
Clément Albergel,P. de Rosnay,C. Gruhier,Joaquín Muñoz-Sabater,S. Hasenauer,Lars Isaksen,Yann Kerr,Wolfgang Wagner +7 more
TL;DR: In this article, in situ soil moisture data from more than 200 stations located in Africa, Australia, Europe and the United States are used to determine the reliability of three soil moisture products, one analysis from the ECMWF (European Centre for Medium-Range Weather Forecasts) numerical weather prediction system (SM-DAS-2) and two remotely sensed soil moisture product, namely ASCAT (Advanced scatterometer) and SMOS (Soil Moisture Ocean Salinity).
