Understanding the geographic scope of THESS

The term 'Trans-Himalaya' has different meanings across geographic contexts and scientific disciplines. For Trans-Himalaya Earth System Science (THESS), the geographic scope is purposefully broad.

Defining the geographic scope

THESS encompasses an extensive network of mountain systems and high-elevation environments across Asia, including the Hindu Kush, Karakoram, Himalaya, Pamir, Tien Shan, Kunlun, Qilian, Altai and Hengduan mountains, together with the Tibetan Plateau; this list is illustrative rather than exhaustive. Collectively, these areas broadly correspond to the regions commonly described as High Mountain Asia and the Third Pole.

This interpretation of the Trans-Himalaya is intentionally inclusive. Rather than establishing a new geographic definition or prescribing rigid spatial boundaries, the journal aims to bring together research across these mountain systems and their surrounding environments—Earth system processes do not follow conventional geographic divisions.

Research submitted to THESS need not cover a large geographic area: contributions can range from individual sites and local environments to regional assessments and broader analyses of the entire Trans-Himalaya. For example, a study focused on a single glacier or ecosystem within the region can be just as geographically relevant as one examining patterns across multiple mountain ranges.

Connections beyond the Trans-Himalaya

THESS also extends beyond mountains and high-elevation environments. It encompasses surrounding and downstream environments that are directly connected to, influenced by, or themselves influence the Trans-Himalaya. Examples include impacts on downstream water resources or atmospheric teleconnections with distant regions.

Research involving other regions can also be relevant where it contributes directly to understanding Earth system processes in the Trans-Himalaya. For example, a comparative study involving the Hindu Kush–Himalaya and the Andes could fall within scope, whereas research focused exclusively on the Andes, without direct relevance to the Trans-Himalaya, would not.

Geographic relevance as a guiding principle

Ultimately, geographic suitability is determined not simply by where the research is conducted, but by its direct relevance to understanding the Trans-Himalaya and its connections with the wider Earth system. So, if you are considering submitting to THESS, ask yourself: How do my findings advance scientific understanding of the Trans-Himalaya? If you can identify a clear and direct contribution, your research is likely to fall within the journal's geographic scope; if you cannot, THESS is unlikely to be the right journal for your work.

However, geographic relevance alone does not determine whether a manuscript is suitable for publication in THESS. Manuscripts must also offer meaningful new scientific insights, as explained in the companion article, Understanding scientific novelty at THESS.
