RISThe Tropical Atmospheric El Niño Signal in Satellite Precipitation Data and a Global Climate Model
Publisher: American Meteorological Society
Abstract: Aspects of the tropical atmospheric response to El Niño related to the global energy and water cycle are examined using satellite retrievals from the Tropical Rainfall Measuring Mission and the Advanced Microwave Scanning ...
Global Energy and Water Budgets in MERRA
Publisher: American Meteorological Society
Abstract: eanalyses, retrospectively analyzing observations over climatological time scales, represent a merger between satellite observations and models to provide globally continuous data and have improved over several generations. ...
The Spatiotemporal Structure of Twentieth-Century Climate Variations in Observations and Reanalyses. Part I: Long-Term Trend
Publisher: American Meteorological Society
Abstract: The dominant interannual El Niño?Southern Oscillation (ENSO) phenomenon and the short length of climate observation records make it difficult to study long-term climate variations in the spatiotemporal domain. Based on the ...
Attribution of the Seasonality and Regionality in Climate Trends over the United States during 1950–2000
Publisher: American Meteorological Society
Abstract: The observed climate trends over the United States during 1950?2000 exhibit distinct seasonality and regionality. The surface air temperature exhibits a warming trend during winter, spring, and early summer and a modest ...
The Spatiotemporal Structure of Twentieth-Century Climate Variations in Observations and Reanalyses. Part II: Pacific Pan-Decadal Variability
Publisher: American Meteorological Society
Abstract: The spatiotemporal structure of Pacific pan-decadal variability (PDV) is isolated in global long-term surface temperature (ST) datasets and reanalysis atmospheric parameter fields from which El Niño?Southern Oscillation ...
Evaluation of Global Precipitation in Reanalyses
Publisher: American Meteorological Society
Abstract: Retrospective-analysis (or reanalysis) systems merge observations and models to provide global four-dimensional earth system data encompassing many physical and dynamical processes. Precipitation is one critical diagnostic ...
A Comparison of MERRA and NARR Reanalyses with the DOE ARM SGP Data
Publisher: American Meteorological Society
Abstract: tmospheric states from the Modern-Era Retrospective analysis for Research and Applications (MERRA) and the North American Regional Reanalysis (NARR) are compared with data from the Atmospheric Radiation Measurement Program ...
The Effect of Satellite Observing System Changes on MERRA Water and Energy Fluxes
Publisher: American Meteorological Society
Abstract: ike all reanalysis efforts, the Modern Era Retrospective-Analysis for Research and Applications (MERRA) must contend with an inhomogeneous observing network. Here the effects of the two most obvious observing system epoch ...
MERRA: NASA’s Modern-Era Retrospective Analysis for Research and Applications
Publisher: American Meteorological Society
Abstract: he 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 ...
