Land-ocean-atmosphere interactions play an important role in modulating the weather and climate processes at local, regional and global scales. In particular, the South Asian monsoon system is one of the most important in the world for driving forest ecosystem, cropping cycle, environmental hazards and terrestrial outflow to the coastal zones. Although the monsoon manifests the natural cycle in the land-ocean-atmosphere interactions, human perturbations are showing large impacts on living conditions of the Earth's environment. In the recent years, management of resources on land are identified as critical for achieving the sustainable development goals (SDGs) of the United Nations (www.un.org). The activities on land, such as forest clearance for cities, river water management for our livelihood and air pollution and greenhouse gas emissions due to industrial activities, have clear consequences for a sustainable future. Many of the ecosystem processes in coastal zones can be altered by the riverine outflow and atmospheric deposition, which could have serious impact on the marine resources and greenhouse gas cycling. An improved understanding of the land-ocean-atmosphere interactions will therefore allow us to manage terrestrial and coastal resources nationally to maximise benefits on people's livelihood as well as environmental protection. In this international workshop, we intend to bring together early career scientists and senior scientists from India and abroad such as SAARC countries with proven work experience in the topics of terrestrial biosphere, oceanic processes and atmospheric trace gases and aerosols. The workshop will allow doctoral students and early career researchers to see how their work fits into the broad canvas of land-ocean-atmosphere interactions. A series of talks and hands-on training on concepts, measurements and data analysis will be conducted as part of this workshop. Over the period of 2 weeks, the participants will be able to interact on possible research projects and design experiments for further explorations jointly with the world's leading scientists. The training will also provide an opportunity to visit a land-ocean boundary based coastal ecosystem in the Sundarbans, a region that experience 3rd largest river discharge in the world through the Ganges-Brahmaputra-Meghna outflow.
