An Investigation on Seasonal and Diurnal Cycles of TOA Shortwave Radiations from DSCOVR/EPIC, CERES, MERRA-2, and ERA5

open access: yesRemote Sensing, 2021
Reflected shortwave (SW) solar radiations at the top of atmosphere from Clouds and the Earth’s Radiant Energy System (CERES), Modern Era-Retrospective analysis for Research and Applications version 2 (MERRA-2), and ECMWF Reanalysis 5th Generation (ERA5 ...

Intercomparison and Uncertainty Assessment of Nine Evapotranspiration Estimates Over South America [PDF]

open access: yes, 2018
This study examines the uncertainties and the representations of anomalies of a set of evapotranspiration products over climatologically distinct regions of South America. The products, coming from land surface models, reanalysis, and remote sensing, are

South Atlantic explosive cyclones in 2014-2015: study employing NCEP2 and MERRA-2 reanalyses

open access: yesAnais da Academia Brasileira de Ciências, 2022
An analysis of explosive cyclone cases was produced by comparing the reanalysis of MERRA-2 (high spatial resolution) and NCEP2 (low spatial resolution) to South Atlantic in the 2014-2015 period.

Successive MJO propagation in MERRA‐2 reanalysis [PDF]

open access: yesGeophysical Research Letters, 2017
AbstractComposite circumnavigating Madden‐Julian oscillation (MJO) events in Version 2 of the NASA Modern Era Reanalysis for Research and Applications (MERRA‐2) reanalysis propagate as convectively coupled Kelvin waves over the Western Hemisphere and moisture waves like that described by Adames and Kim (2016) over the warm pool.

Biases of Global Tropopause Altitude Products in Reanalyses and Implications for Estimates of Tropospheric Column Ozone

open access: yesAtmosphere, 2021
Accuracy of global tropopause altitude products from reanalyses is important to applications of the products, including the derivation of tropospheric column ozone (TCO).

Improving InSAR geodesy using global atmospheric models [PDF]

open access: yes, 2014
Spatial and temporal variations of pressure, temperature and water vapor content in the atmosphere introduce significant confounding delays in Interferometric Synthetic Aperture Radar (InSAR) observations of ground deformation and bias estimatesof ...

Modelling the Swedish wind power production using MERRA reanalysis data

open access: yesRenewable Energy, 2015
AbstractThe variability of wind power will be an increasing challenge for the power system as wind penetration grows and thus needs to be studied. In this paper a model for generation of hourly aggregated wind power time series is described and evaluated.

Evaluation of Hourly PWV Products Derived From ERA5 and MERRA‐2 Over the Tibetan Plateau Using Ground‐Based GNSS Observations by Two Enhanced Models

open access: yesEarth and Space Science, 2021
Precipitable water vapor (PWV), despite being the key factor for assessing climate change over the Tibetan Plateau (TP), is undersampled in this region due to the complex terrain and climate conditions therein.

The evolution of bits and bottlenecks in a scientific workflow trying to keep up with technology: Accelerating 4D image segmentation applied to nasa data [PDF]

open access: yes, 2019
In 2016, a team of earth scientists directly engaged a team of computer scientists to identify cyberinfrastructure (CI) approaches that would speed up an earth science workflow. This paper describes the evolution of that workflow as the two teams bridged

A new satellite-based global climatology of dust aerosol optical depth [PDF]

open access: yes, 2020
By mass, dust is the largest contributor to global aerosol burden, yet long-term observational records of dust, particularly over the ocean, are limited.
