Atmospheric Reanalysis: Overview & Comparison Tables
Years of record
- N/A
Reanalysis a systematic approach to produce data sets for climate monitoring and research. 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…

Years of record
- to
The CERES-EBAF product provides 1-degree regional, zonal and global monthly mean Top-of-Atmosphere (TOA) and surface (SFC) longwave (LW), shortwave (SW), and net (NET) fluxes under clear and all-sky conditions. EBAF is used for climate model evaluation, estimating the Earth's global mean energy budget, and to infer meridional heat transport. The data synthesized to…

CMAP: CPC Merged Analysis of Precipitation
Years of record
- to
CMAP refers to a collection of precipitation data sets, though the 2.5°x2.5° global monthly version is probably the most widely used. This data set is constructed from an analysis of gauge data and satellite-derived precipitation estimates. An "enhanced" version (CMAP/A) is also available, which provides global coverage by filling in gaps with precipitation forecasts…

Combined CloudSat spaceborne radar and CALIPSO spaceborne lidar cloud fraction dataset (3S-GEOPROF-COMB)
Years of record
- to
A global (82S-82N) cloud fraction data set, providing a unique view of cloud vertical structure, has been developed based on the complimentary spaceborne remote sensing capabilities of the CloudSat radar and the CALISPSO lidar. The data set provides monthly mean cloud fraction over several vertical layers for 2006-2019.

COSP: Cloud Feedback Model Intercomparison Project (CFMIP) Observation Simulator Package
Years of record
- N/A
Cloud processes and feedbacks are recognized as the largest uncertainty in climate model projections of climate change. Progress in understanding the roles of clouds in climate change has in part been hampered by the lack of a consistent definition of clouds and cloud types in models and observations. It has been difficult to compare model output to observations, or even…

ERA-Interim
Years of record
- to
Using a much improved atmospheric model and assimilation system from those used in ERA-40, ERA-Interim represents a third generation reanalysis. Several of the inaccuracies exhibited by ERA-40 such as too-strong precipitation over oceans from the early 1990's onwards and a too-strong Brewer-Dobson circulation in the stratosphere, were eliminated or significantly reduced…

Data from rain gauge stations, satellites, and sounding observations have been merged to estimate monthly rainfall on a 2.5-degree global grid from 1979 to the present. The careful combination of satellite-based rainfall estimates provides the most complete analysis of rainfall available to date over the global oceans, and adds necessary spatial detail to the rainfall…

This digital archive provides multi-year monthly, seasonal, and annual averages in 5x5-degree grid boxes (or 10x10-degree boxes for some quantities over the ocean). Daytime and nighttime averages, as well as the diurnal average (average of day and night), are given. Nighttime averages were computed using only those reports that met an "illuminance criterion" (i.e., made…

NCEP-NCAR (R1) is the original reanalysis effort. It uses a frozen global state-of-the-art global data assimilation system (as of 11 January 1995). The original database was enhanced (additional, quality checked datasets) by NCAR's Data Support Section. Originally planned to span 1957-96 ("40-Year Reanalysis Project"), it was extended back to 1948 and continues to this…
