Estimating variability in downwelling surface shortwave radiation in a tropical highland environment.

open access: yesPLoS ONE, 2019
Surface incoming shortwave (solar) radiation data are an important component of many scientific analyses, but direct measurements are not commonly available.

The role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We use the Advanced Weather Research and Forecasting model to examine the role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems (LPSs). We find that LPSs penetrate deeply into India despite a dry land surface; however, their inland penetration is adversely affected when there is a reduction in the total surface heat ...

Comparative Evaluation of Satellite- Based Merra-2 against Ground-based Data for PM2.5 and TC Concentrations in Ghaziabad, India [PDF]

open access: yesE3S Web of Conferences
This study compares satellite-based observations of PM2.5 and Total Carbon (TC) concentrations derived from NASA’s MERRA-2 reanalysis dataset for the Ghaziabad region with ground-based observations at two sites (Site A and Site B) from June 2018 to May ...

Evaluation of PM2.5 Surface Concentrations Simulated by NASA’s MERRA Version 2 Aerosol Reanalysis over India and its Relation to the Air Quality Index

open access: yesAerosol and Air Quality Research, 2020
The PM2.5 (particulate matter with a diameter ≤ 2.5 µm), an essential component of air pollution, is closely linked to adverse effects on human health, including premature mortality following prolonged exposure.

The Fusion of ERA5 and MERRA-2 Atmospheric Temperature Profiles with Enhanced Spatial Resolution and Accuracy

open access: yesRemote Sensing, 2023
Accurate high-resolution atmospheric temperature profiles are essential for precisely characterizing the evolution of the atmosphere and developing numerical forecasts. Atmospheric datasets, such as ERA5 (the fifth-generation ECMWF Reanalysis) and MERRA-2 (the Modern-Era Retrospective Analysis for Research and Applications, Version 2), provide global ...

Moisture inversions in the central Arctic: Product assessment and long‐wave radiative effect

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study evaluates the integrated water vapour and the vertical distribution of water vapour of state‐of‐the‐art reanalyses, weather forecast models, and ground‐ and space‐based remote‐sensing products in the central Arctic. A particular focus lies on the representation of humidity inversions and the quantification of the long‐wave radiative effect ...

Machine Learning Model Optimization for Antarctic Blowing Snow Height and Optical Depth Diagnosis

open access: yesAtmosphere
Blowing snow is a common phenomenon over the Antarctic ice sheet and sea ice regions, playing a crucial role in the Antarctic climate system. Previous research developed an optimized machine learning (ML) model to diagnose blowing snow occurrence using ...

Observed Tightening of Tropical Ascent in Recent Decades and Linkage to Regional Precipitation Changes [PDF]

open access: yes, 2020
Climate models predict that the tropical ascending region should tighten under global warming, but observational quantification of the tightening rate is limited.

Indian and African monsoons: Trajectories and interactions

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The catch basin of marine air particles of the Indian monsoon is the tropical Indian ocean, whilst that of the African monsoon is the east tropical Atlantic. However, the oscillations induced by the monsoonal interactions favour particle exchange between the two basins. These transitions are abrupt in the presence of stochastic resonance. The monsoonal

Host Phylogeny and Feeding Habit Jointly Govern Mammalian Gut Microbiota Composition

open access: yesIntegrative Zoology, EarlyView.
Herbivores showed higher alpha diversity than carnivores/omnivores, while omnivores had the highest beta diversity. Host phylogeny influenced gut microbiota more strongly in herbivores/omnivores, with phylogenetic distance correlating to microbiota dissimilarity.
