Tracing Water Sources and Fluxes in a Dynamic Tropical Environment: From Observations to Modeling

open access: yesFrontiers in Earth Science, 2020
Tropical regions cover approximately 36% of the Earth’s landmass. These regions are home to 40% of the world’s population, which is projected to increase to over 50% by 2030 under a remarkable climate variability scenario often exacerbated by El Niño ...

Rainfall, groundwater, and surface water isotope data from extreme tropical cyclones (2016-2019) within the Caribbean Sea and Atlantic Ocean basins

open access: yesData in Brief, 2020
Under a changing climate, projections estimate that over the next thirty years, extreme Tropical Cyclones (TCs) will increase in frequency, with two to three times more Category 4 and 5 hurricanes in the Atlantic basin between 20°N and 40°N.

Search for lithium isotope effects in neuronal HT22 cells

open access: yesBiochemistry and Biophysics Reports, 2023
Lithium has been used as a treatment for bipolar disorder for over half a century, but there has thus far been no clinical differentiation made between the two naturally occurring stable isotopes (6Li and 7Li).

The main controls of the precipitation stable isotopes at Kathmandu, Nepal

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2020
Precipitation stable isotopes (2H and 18O) are adequately understood on their climate controls in the Tibetan Plateau, especially the north of Himalayas via about 30 years’ studies. However, knowledge of controls on precipitation stable isotopes in Nepal
