Climatology and Decadal Changes of Arctic Atmospheric Rivers Based on ERA5 and MERRA-2

open access: yesEnvironmental Research: Climate, 2023
We present {the} Arctic atmospheric river (AR) climatology based on twelve {sets of} labels 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 ($IVT$

Wind Power Cogeneration to Reduce Peak Electricity Demand in Mexican States Along the Gulf of Mexico [PDF]

open access: yes, 2019
The Energetic Transition Law in Mexico has established that in the next years, the country has to produce at least 35% of its energy from clean sources in 2024.

Assessment of MERRA-2 Land Surface Energy Flux Estimates [PDF]

open access: yesJournal of Climate, 2018
In the Modern-Era Retrospective Analysis for Research and Applications version 2 (MERRA-2) system the land is forced by replacing the model-generated precipitation with observed precipitation before it reaches the surface. This approach is motivated by the expectation that the resultant improvements in soil moisture will lead to improved land surface ...

Atmospheric Water Balance and Variability in the MERRA-2 Reanalysis

open access: yesJournal of Climate, 2017
Abstract Closing and balancing Earth’s global water cycle remains a challenge for the climate community. Observations are limited in duration, global coverage, and frequency, and not all water cycle terms are adequately observed. Reanalyses aim to fill the gaps through the assimilation of as many atmospheric water vapor observations as ...

Improved rainfall and temperature satellite dataset in areas with scarce weather stations data: case study in Ancash, Peru

open access: yesRevista de Teledetección, 2022
Rainfall and temperature variables play an important role in understanding meteorology at global and regional scales. However, the availability of meteorological information in areas of complex topography is difficult, as the density of weather stations ...

Discontinuities in the Ozone Concentration Time Series from MERRA 2 Reanalysis [PDF]

open access: yesAtmosphere, 2019
Artificial discontinuities in time series are a great problem for trend analysis because they influence the values of the trend and its significance. The aim of this paper is to investigate their occurrence in the Modern-Era Retrospective analysis for Research and Applications, version 2 (MERRA 2) ozone concentration data.

Inter-annual and seasonal patterns of precipitable water vapour over Malaysia from 1990–2019 based on MERRA-2 reanalysis

open access: yesPrzegląd Naukowy Inżynieria i Kształtowanie Środowiska, 2021
In this study seasonal and inter-annual patterns as well as trend in the total precipitable water vapour (TPW) over Malaysia, based on a 30-year data from MERRA-2, have been evaluated using least square regression method. Indicator TPW revealed a pair of

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.

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).

An Assessment of NASA’s GMAO MERRA-2 Reanalysis Surface Winds [PDF]

open access: yesJournal of Climate, 2019
Abstract The quality of MERRA-2 surface wind fields was assessed by comparing them with 10 years of measurements from a wide range of surface wind observing platforms. This assessment includes a comparison of MERRA-2 global surface wind fields with the ones from its predecessor, MERRA, to assess if GMAO’s latest reanalyses improved the ...
