PBL Height From AIRS, GPS RO, and MERRA‐2 Products in NASA GES DISC and Their 10‐Year Seasonal Mean Intercomparison

open access: yesEarth and Space Science, 2021
Within the planetary boundary layer (PBL), surface forcing response, drag, turbulence, and vertical mixing are important processes and play a more critical role here than in the overlying “free atmosphere.” The PBL height (PBLH) is an important parameter

Performance evaluation of ERA-5, JRA-55, MERRA-2, and CFS-2 reanalysis datasets, over diverse climate regions of Pakistan

open access: yesWeather and Climate Extremes, 2021
Reanalysis precipitation products (RPPs) are frequently used for studying the water cycle changes from short to long-term scale globally. In the current study, ERA-5 produced by the European Centre for Medium-Range Weather Forecasts (ECMWF), the Japanese

Decadal Changes of UV Aerosol Optical Depth in Hobart, Australia Measured With a Brewer MKIII: Relationship to Bushfire Events and Climate Indices

open access: yesInternational Journal of Climatology, EarlyView.
Monthly average aerosol optical depth at 320 nm obtained with a Brewer MKIII spectrophotometer for Hobart, Australia (42.8806° S, 147.3250° E) over a 21‐year period. There is a linear trend of 15.4% per decade. There are 9 months when the average aerosol optical depth exceeds twice the monthly standard deviation.

Can MERRA-2 Reanalysis Data Reproduce the Three-Dimensional Evolution Characteristics of a Typical Dust Process in East Asia? A Case Study of the Dust Event in May 2017

open access: yesRemote Sensing, 2020
This study used the MERRA-2 reanalysis dataset and ground-based and satellite observational data to comprehensively analyze a typical dust storm event in east Asia on 2−7 May 2017 which engulfed most of China as well as ocean and Japan, and explore

Sustenance of phytoplankton in the subpolar North Atlantic during the winter through patchiness [PDF]

open access: yes, 2017
This study investigates the influence of two factors that change the mixed layer depth and can potentially contribute to the phytoplankton sustenance over winter: 1) variability of air-sea fluxes and 2) three-dimensional processes arising from strong ...

Outcomes and adverse effects of teduglutide treatment with periodic withdrawal in pediatric short bowel patients

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives We evaluated the efficacy and safety of teduglutide in a real‐world cohort in which national reimbursement policies required treatment interruptions. The primary outcomes were reduction in parenteral support (PS) and treatment‐related adverse effects, and the secondary outcome was the impact of the mandated withdrawal periods ...

Deciphering Freeze–Thaw Dynamics In Rockwalls: A Novel Approach for High Accuracy Regional‐Scale Modeling

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Using a large and novel array of instruments on five rockwalls in northern Gaspesia, their respective surface energy balances were calculated and their thermal regimes were measured and modeled to depths exceeding the seasonal frost penetration.

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 ...

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 ...

Validation of Surface Temperature Derived From MERRA‐2 Reanalysis Against IMD Gridded Data Set Over India

open access: yesEarth and Space Science, 2020
The first detailed validation of maximum temperature of Modern‐Era Retrospective analysis for Research and Application Version 2 (TMERRA‐2) against Indian Meteorological Department (TIMD) has been carried out for 35 years (1981–2015) over India. For this
