Data Catalogue

The four continental scale groundwater models that constitute GLOBGM - a global groundwater model. Dark overlays indicate the presence of a confining layer and grids visualises the data structure regarding the two model layers.

GLOBGM employs a two-layer groundwater model, with outputs available for both layers. Layer 1 (l1) represents the shallow, unconfined aquifer system (potentially including a confining unit), while Layer 2 (l2) models the deeper, confined aquifer. Properly interpreting these layers is essential for selecting the appropriate data in your analysis.

The aquifer type at any location is determined by the data presence in each layer:

Confined System: Occurs where Layer 1 contains valid data, representing the confining layer (aquitard), with Layer 2 data corresponding to the underlying confined aquifer.
Unconfined System: Identified where Layer 1 is null (no data) and Layer 2 has valid data, indicating an unconfined aquifer in Layer 2.
