Tropical Cyclone Characteristics in the MERRA‐2 Reanalysis and AMIP Simulations [PDF]

Earth and Space Science, 2021
This study evaluates the tropical cyclone (TC) activity in two high‐resolution data sets—MERRA‐2 Reanalysis (Modern‐Era Retrospective Analysis for Research and Applications, Version 2) and MERRA‐2 AMIP (Atmospheric Model Intercomparison Project).

Evaluation of MERRA-2 and MODIS C6.1 aerosol products over Indonesia [PDF]

E3S Web of Conferences
Atmospheric aerosols play an essential role in atmospheric chemistry and climate. Amidst the issue of climate change, analysis of at-mospheric aerosols based on satellite and reanalysis is needed to estimate radiative forcing by aerosols, completing the ...

Validação da reanálise do MERRA-2 com dados observados

Metodologias e Aprendizado, 2021
Climate data such as temperature are key to understand a place’s dynamic. Since the classic period to study climate is thirty years, some areas face difficulties due to the lack of broad data record. Thus, one solution to this situation is the employment

Structure and Dynamics of the Quasi-Biennial Oscillation in MERRA-2. [PDF]

J Clim, 2016
Abstract The structure, dynamics, and ozone signal of the quasi-biennial oscillation (QBO) produced by the 35-yr NASA Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), are examined based on monthly mean output. Along with the analysis of the QBO in assimilation winds and ozone, the QBO forcings created

A Global Climatology of Tropopause Folds in CAMS and MERRA‐2 Reanalyses [PDF]

Journal of Geophysical Research: Atmospheres, 2021
AbstractTropopause folds are the main mechanism underlying stratosphere‐to‐troposphere transport and influence tropospheric composition and weather systems by triggering convection. Here, we present the global climatology of tropopause folds in Copernicus Atmosphere Monitoring Service (CAMS) and Modern‐Era Retrospective analysis for Research and ...

Evaluation of Southern Ocean cloud in the HadGEM3 general circulation model and MERRA-2 reanalysis using ship-based observations [PDF]

Atmospheric Chemistry and Physics, 2020
Southern Ocean (SO) shortwave (SW) radiation biases are a common problem in contemporary general circulation models (GCMs), with most models exhibiting a tendency to absorb too much incoming SW radiation. These biases have been attributed to deficiencies
