Lato Basin Glacier and Lake Dynamics with GLOF Risk Assessment, 1980-2020

A multi-parameter assessment of the Lato glacier–lake system in Trans-Himalayan Ladakh over a 40-year period (1980–2020). The dataset likely contains measurements of glacier area reduction, terminus retreat, ice volume, surface velocities, lake expansion, and GLOF risk indices derived from remote sensing, empirical modeling, and hydrodynamic simulations. It was authored by Rayees Ahmed and published on figshare under a CC-BY-4.0 license.

Use Cases

• Modeling glacier retreat rates based on the reported 11.5% area reduction and 4.2 m yr⁻¹ terminus retreat.
• Assessing proglacial lake expansion and volume based on the 66% growth and estimated 1.47 × 10⁶ m³ volume.
• Evaluating Glacial Lake Outburst Flood (GLOF) susceptibility using the reported high-risk index of 0.82.
• Simulating downstream flood impacts based on hydrodynamic simulation results forecasting peak discharges up to 3726 m³s⁻¹.

Strengths

• Covers a 40-year time series (1980–2020) for longitudinal analysis.
• Integrates multiple assessment methods including remote sensing, empirical modeling (GlabTop2), and hydrodynamic simulation (HEC-RAS).
• Provides specific quantitative results such as glacier volume decline from 0.48 km³ to 0.41 km³ and lake expansion to 0.088 km².

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (24.2 KB), suggesting it may be a summary table rather than raw observational data.
