Atlas of Arctic Atmospheric River Climatology Based on ERA5 and MERRA-2
2022We present an atlas of Arctic atmospheric river (AR) climatology based on twelve indices derived from ERA5 and MERRA-2 reanalyses for 1980–2019. The ARs were identified and tracked in the 3-hourly reanalysis data with a multifactorial approach based on either atmospheric column-integrated water vapor ($IWV$) or integrated water vapor transport ($IVT ...

The Role of Analysis Error in the Convergence of Reanalysis Production Streams in MERRA-2
Monthly Weather Review, 2021ABSTRACTDue to production time constraints, most reanalyses are produced in multiple parallel streams instead of a single continuous one. These streams cover separate segments of the reanalysis time period with short overlaps to allow reconstruction of the official record.

The Driving Factors of Global Land Surface Albedo: An Analysis with the Glass and Merra-2 Data
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Land surface albedo is an important parameter in surface energy budget, which determines the reflected/absorbed fraction of shortwave solar radiation of land surfaces. As the land surface albedo is highly spatio-temporal dynamic, it is important to understanding the spatial patterns of the leading factors of land surface albedo.

A Mediterranean Sea Offshore Wind classification using MERRA-2 and machine learning models
Renewable Energy, 2022This paper uses a Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2) re-analysis to identify long-term Mediterranean Sea Offshore Wind (OW) classification possible locations. In particular, an OW classification based on the last 40-years period OW speeds highlighted the best areas for potential Offshore Wind Turbine ...

Atmospheric Aerosol Prediction over Egypt with LSTM-RNN using NASA’s MERRA-2
2020 2nd Novel Intelligent and Leading Emerging Sciences Conference (NILES), 2020Aerosol optical depth (AOD) is one of the most critical indicators for air quality. Estimation of accurate AOD needs to include both dust and chemical reactions in the calculations which are expensive from a computational point of view. In this work, we present a novel and simple model to estimate and predict the temporal trend of AOD based on the well-

Multifractality of meteorological time series for Poland on the base of MERRA-2 data
Chaos, Solitons & Fractals, 2019Abstract Spatial variability of the multifractal properties of a 36-year-long meteorological time series for Poland coming from the MERRA-2 database was analysed. It constitute a very valuable source of meteorological data, as high similarity with ground data recorded at meteorological stations in the region of interest was stated by the analysis of ...

Evaluation of MERRA-2 reanalysis for Sulfur dioxide aerosol in China
Considering the uncertainty of the reanalysis data is essential, the uncertainty of Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2) SO2 concentration still is lacking. In this talk, we evaluated the MERRA-2 SO2 concentrations in China. Monthly SO2 concentrations from 100 ground observation during the years 2015-2021Abdallah Shaheen +4 more
