Climate Forecast System Reanalysis (CFSR)
Years of Record: 1979/01 to 2017/11
The CFSR is a third generation reanalysis product. It is a global, high resolution, coupled atmosphere-ocean-land surface-sea ice system designed to provide the best estimate of the state of these coupled domains over this period. The CFSR includes (1) coupling of atmosphere and ocean during the...

ERA-Interim
Years of Record: 1979/01 to 2017/09
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...

HOAPS: Hamburg Ocean Atmosphere Parameters and Fluxes from Satellite Data
Years of Record: 1987/01 to 2008/12
The Hamburg Ocean Atmosphere Parameters and Fluxes from Satellite Data (HOAPS) set is a satellite-based climatology of precipitation, evaporation and freshwater budget (evaporation minus precipitation) as well as related turbulent heat fluxes and atmospheric state variables over the global ice free...

JRA-25
Years of Record: 1979/01 to 2004/12
JRA-25 is a second generation reanalysis product. The model and data assimilation are from the operational system in April 2004. It was the first reanalysis to assimilate wind profiles around tropical cyclones deduced from best-track data, resulting in improved tropical cyclone analysis in a global...

JRA-55
Years of Record: 1957/12 to 2017/07
Spanning 1958-present, JRA-55 is the longest third-generation reanalysis that uses the full observing system (in contrast, products like ERA-20C and NOAA 20CR assimilate a very limited set of observations while NCEP R1 uses an antiquated model and assimilation scheme).  Compared to the...

Liquid Water Path (LWP): UWisc climatology
Years of Record: 1998/01 to 2008/12
"This work describes a new climatology of cloud liquid water path (LWP), termed the University of Wisconsin (UWisc) climatology, derived from 18 yr of satellite-based passive microwave observations over the global oceans. The climatology is based on a modern retrieval methodology applied...

NASA MERRA
Years of Record: 1979/01 to 2016/11
The Modern Era Retrospective-Analysis for Research and Applications (MERRA) was undertaken by NASA’s Global Modeling and Assimilation Office with two primary objectives: to place observations from NASA’s Earth Observing System satellites into a climate context and to improve upon the hydrologic...

NCEP NARR
Years of Record: 1979/01 to 2017/11
A high resolution (32km x 29 pressure levels) data set focused upon the North American Region. Relative to the NCEP-DOE (R2) it has a much improved land-hydrology, diurnal cycle and land-atmosphere interaction. As such, it can be considered a second generation reanalysis. A unique feature is the...

NCEP Reanalysis (R2)
Years of Record: 1979/01 to 2017/11
NCEP-DOE Reanalysis II (R2) is an improved version of the NCEP-NCAR Reanalysis I (R1). The improvements include an updated model with better physical parameterizations, assorted data assimilation errors were fixed and additional data were included. Still, it is still a 'first generation' product.
