This resource contains code and input data to develop a high-resolution (0.1°) gridded global glacier and ice sheet fractional area dataset, which is also available in this resource. The dataset is developed from Randolph Glacier Inventory v6.0 shapefiles and supplementary shapefiles for the Antarctic and Greenland ice sheets. The approach is adapted from Li et al., (2021; https://doi.org/10.1017/jog.2021.28). The dataset provides estimates of the fraction (0 to 1) of land cover that is glaciated in each 0.1° x 0.1° grid cell. The dataset was designed for use in the SPEAR model (https://www.gfdl.noaa.gov/spear/) from the NOAA Geophysical Fluid Dynamics Laboratory (GFDL), but may be useful for other applications as well. This work is documented in a NOAA Technical Memorandum (citation information to follow).
