IceBoost v2.0 Regional Merged Mosaics for RGI v6.0 and RGI v7.0

This repository contains the IceBoost v2.0 regional merged mosaics for Randolph Glacier Inventory (RGI) v6.0 and v7.0.

• RGI v.6: regional folders from 1 to 19.
• RGI v.7: regional folders from 1 to 19.

Each .tif file contains the distributed ice thickness of all glaciers merged together. The files have the following format: iceboost_20251009_rgixx_vyy_epsg_zzzz.tif

- xx: value from 1 to 19
- yy: 62 for RGI6 or 70G for RGI7.
- zzzz: epsg regional code.

(example iceboost_20251009_rgi4_v70G_epsg_32617.tif).

File Data layers: 

• IceBoost v2.0-modeled ice thickness
• Monte Carlo-modeled ice thickness uncertainty
• Jensen Gap
• Surface Elevation (TanDEM-X Edited DEM v1, more info here)
• Geoid Height (EIGEN-6C4 gravity field)

Data type: float32.
CRS: coordinates, measured in meters within a specific UTM zone.
Spatial resolution: 100 meters.
Nodata: np.nan

File Attributes:

• Ice volume (with uncertainty): complex ice volume (with uncertainty).
• Ice volume below sea level (with uncertainty): complex ice volume below sea level (with uncertainty).
• Area: complex area.
• Ice thickness measurements contained within the complex, if any: latitude, longitude, ice thickness.
  
  

Note: individual glaciers may be produced with a finer resolution than 100 meters. The merged mosaics, however, are generated at a fixed 100 meter resolution. For smaller glaciers we refer the users to the individual glacier product at https://zenodo.org/records/17724512.
