API reference

Here we will add the documentation for selected modules.

Entity tasks

define_glacier_region Very first task: define the glacier’s grid.
glacier_masks Converts the glacier vector geometries to grids.
compute_centerlines Compute the centerlines following Kienholz et al., (2014).
compute_downstream_lines Compute the lines continuing the glacier (one per divide).
catchment_area Compute the catchment areas of each tributary line.
initialize_flowlines Transforms the geometrical Centerlines in the more “physical” InversionFlowlines.
catchment_width_geom Compute geometrical catchment widths for each point of the flowlines.
catchment_width_correction Corrects for NaNs and inconsistencies in the geometrical widths.
mu_candidates Computes the mu candidates.
prepare_for_inversion Prepares the data needed for the inversion.
volume_inversion Computes the inversion the glacier.
distribute_thickness Compute a thickness map of the glacier using the nearest centerlines.
init_present_time_glacier First task after inversion.
find_inital_glacier Search for the glacier in year y0

Global tasks

distribute_climate_data Reads the climate data and distributes to each glacier.
compute_ref_t_stars Detects the best t* for the reference glaciers.
distribute_t_stars After the computation of the reference tstars, apply the interpolation to each individual glacier.
optimize_inversion_params Optimizes fs and fd based on GlaThiDa thicknesses.

Classes

GlacierDirectory Organizes read and write access to the glacier’s files.

Mass-balance

Mass-balance models in the oggm.core.models.massbalance module

TstarMassBalanceModel Constant mass balance: equilibrium MB at period t*.
BackwardsMassBalanceModel Constant mass balance: MB for [1983, 2003] with temperature bias.
TodayMassBalanceModel Constant mass-balance: MB during the last 30 yrs.
HistalpMassBalanceModel Mass balance during the HISTALP period.
