Land Surface Precipitation in MERRA-2

Journal of Climate, 2017
Abstract The Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), features several major advances from the original MERRA reanalysis, including the use, outside of high latitudes, of observations-based precipitation data products to correct the precipitation falling on the land surface in the MERRA-2 ...

Assessment of MERRA-2 Land Surface Hydrology Estimates

Journal of Climate, 2017
The MERRA-2 atmospheric reanalysis product provides global, 1-hourly estimates of land surface conditions for 1980–present at ~50-km resolution. MERRA-2 uses observations-based precipitation to force the land (unlike its predecessor, MERRA). This paper evaluates MERRA-2 and MERRA land hydrology estimates, along with those of the land-only MERRA-Land ...

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

Anais 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.

The MERRA-2 Aerosol Reanalysis, 1980 Onward. Part II: Evaluation and Case Studies. [PDF]

J Clim, 2017
The Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), is NASA’s latest reanalysis for the satellite era (1980 onward) using the Goddard Earth Observing System, version 5 (GEOS-5), Earth system model. MERRA-2 provides several improvements over its predecessor (MERRA-1), including aerosol assimilation for the entire ...

COMPARISON OF THREE TYPES OF AEROSOL PRODUCTS DURING 2015–2017 IN CHINA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
In this study, we use sunphotometer (AERONET) data as reference to evaluate MODIS, Himawari-08, and MERRA-2 aerosol products over China. AERONET data from Beijing, Xianghe, Xuzhou, Taihu and Hong Kong are used.

Frequency and duration of low-wind-power events in Germany

, 2020
In the transition to a renewable energy system, the occurrence of low-wind-power events receives increasing attention. We analyze the frequency and duration of such events for onshore wind power in Germany, based on 40 years of reanalysis data and open ...

Successive MJO propagation in MERRA‐2 reanalysis [PDF]

Geophysical 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.
