From Drought Propagation to Dryland Expansion: The Role of Land Feedbacks in Spreading Aridity

Akash Koppa

Half a century after Apollo 17's iconic "Blue Marble" photograph, depicting our Earth's life-sustaining hydrosphere, concerns about the future of this hydrosphere have intensified. Climate change is thought to be shifting ecosystems toward drier and more h ...

Dryland self-expansion enabled by land-atmosphere feedbacks

Akash Koppa

Dryland expansion causes widespread water scarcity and biodiversity loss. Although the drying influence of global warming is well established, the role of existing drylands in their own expansion is relatively unknown. In this work, by tracking the air flo ...

Drivers and mechanisms of heatwaves in South West India

Akash Koppa

Under global warming, heatwaves over India are projected to increase unequivocally. Thus, understanding the causal mechanisms responsible for heatwaves adds immense value to the country's climate change mitigation and adaptation strategies. Although severa ...

East-West asymmetry in intensity, duration, frequency of heatwaves over Northern India

Akash Koppa

Anthropogenic global warming has led to widespread increase in the heatwave intensity, duration, and frequency (HIDF) of events across the globe. Although the three characteristics of heatwaves are closely interconnected, they are often studied separately, ...

GLEAM4: global land evaporation and soil moisture dataset at 0.1 resolution from 1980 to near present

Akash Koppa

Terrestrial evaporation plays a crucial role in modulating climate and water resources. Here, we present a continuous, daily dataset covering 1980-2023 with a 0.1 degrees spatial resolution, produced using the fourth generation of the Global Land Evaporati ...
