The Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), is the latest atmospheric reanalysis of the modern satellite era produced by NASA’s Global Modeling and Assimilation Office (GMAO). MERRA-2 assimilates observation types not available to its predecessor, MERRA, and includes updates to the Goddard Earth Observing System (GEOS) model and analysis schem...... hiện toàn bộ MERRA: NASA’s Modern-Era Retrospective Analysis for Research and Applications Tập 24 Số 14 - Trang 3624-3648 - 2011

Abstract
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 cycle represented in earlier generations of rea...... hiện toàn bộ Daily High-Resolution-Blended Analyses for Sea Surface Temperature Tập 20 Số 22 - Trang 5473-5496 - 2007

Abstract
Two new high-resolution sea surface temperature (SST) analysis products have been developed using optimum interpolation (OI). The analyses have a spatial grid resolution of 0.25° and a temporal resolution of 1 day. One product uses the Advanced Very High Resolution Radiometer (AVHRR) infrared satellite SST data. The other uses AVHRR and Adva...... hiện toàn bộ Improvements to NOAA’s Historical Merged Land–Ocean Surface Temperature Analysis (1880–2006) Tập 21 Số 10 - Trang 2283-2296 - 2008

Abstract
Observations of sea surface and land–near-surface merged temperature anomalies are used to monitor climate variations and to evaluate climate simulations; therefore, it is important to make analyses of these data as accurate as possible. Analysis uncertainty occurs because of data errors and incomplete sampling over the historical period. Th...... hiện toàn bộ The NCEP Climate Forecast System Version 2 Tập 27 Số 6 - Trang 2185-2208 - 2014

Abstract
The second version of the NCEP Climate Forecast System (CFSv2) was made operational at NCEP in March 2011. This version has upgrades to nearly all aspects of the data assimilation and forecast model components of the system. A coupled reanalysis was made over a 32-yr period (1979–2010), which provided the initial conditions to carry out a co...... hiện toàn bộ Extended Reconstructed Sea Surface Temperature, Version 5 (ERSSTv5): Upgrades, Validations, and Intercomparisons Tập 30 Số 20 - Trang 8179-8205 - 2017

Abstract
The monthly global 2° × 2° Extended Reconstructed Sea Surface Temperature (ERSST) has been revised and updated from version 4 to version 5. This update incorporates a new release of ICOADS release 3.0 (R3.0), a decade of near-surface data from Argo floats, and a new estimate of centennial sea ice from HadISST2. A number of choices in aspects...... hiện toàn bộ Indian Ocean Capacitor Effect on Indo–Western Pacific Climate during the Summer following El Niño Tập 22 Số 3 - Trang 730-747 - 2009

Abstract
Significant climate anomalies persist through the summer (June–August) after El Niño dissipates in spring over the equatorial Pacific. They include the tropical Indian Ocean (TIO) sea surface temperature (SST) warming, increased tropical tropospheric temperature, an anomalous anticyclone over the subtropical northwest Pacific, and increased ...... hiện toàn bộ Contrasting Eastern-Pacific and Central-Pacific Types of ENSO Tập 22 Số 3 - Trang 615-632 - 2009
Hsun‐Ying Kao, Jin‐Yi Yu
Abstract
Surface observations and subsurface ocean assimilation datasets are examined to contrast two distinct types of El Niño–Southern Oscillation (ENSO) in the tropical Pacific: an eastern-Pacific (EP) type and a central-Pacific (CP) type. An analysis method combining empirical orthogonal function (EOF) analysis and linear regression is used to se...... hiện toàn bộ
