Atmospheric Reanalysis Overview Comparison Tables Climate Data Guide Reanalysis data are often used to represent the "true state of the atmosphere according to observations." in actual fact, reanalysis combines inaccurate and incomplete observations with imperfect models, using methods and procedures that are technically and scientifically complex. For your information, there are several comparison tables for all available global atmospheric reanalyses as of 2016 in the following paper:.
Atmospheric Reanalysis Overview Comparison Tables Climate Data Guide Below is the atmospheric reanalysis overview page, which summarizes the attributes of the major atmospheric reanalyses. this section also includes selected oceanic reanalyses, although an overview is not available yet. Reanalyses are created via an unchanging ("frozen") data assimilation scheme and model (s) which ingest all available observations every 6 12 hours over the period being analyzed. this unchanging framework provides a dynamically consistent estimate of the climate state at each time…. Reanalyses are created via an unchanging ("frozen") data assimilation scheme and model (s) which ingest all available observations every 6 12 hours over the period being analyzed. this unchanging framework provides a dynamically consistent estimate of the climate state at each time…. The guide publishes data summaries with access links, intercomparisons, and expert commentaries on the utility of climate data for addressing a wide variety of questions in climate science.

Overview pages summarize and compare selected datasets of a given variable. to find a specific dataset or variable, jump to the search box below or click your desired variable from among the blue sub category buttons. Era5 is the latest climate reanalysis produced by ecmwf, providing hourly data on many atmospheric, land surface and sea state parameters together with estimates of uncertainty. The merra atlas provides monthly, annual, seasonal and climate comparisons among several of the latest atmospheric reanalyses (including era interim, cfsr, and jra25) and various global observation datasets. Reanalyzed datasets can be used to create a coherent, long term record of past weather by compensating for the inherent biases of the different instruments used to take measurements at different points in the history of weather observation.
