OGGM Shop datasets

OGGM Shop datasets#

The OGGM “shop” is a subpackage (from oggm import shop) containing the code used to process and add the datasets listed below.

You can either add these datasets to existing glacier directories using the shop, or download preprocessed directories with the _w_data suffix, which include all datasets by default (and are therefore larger).

For example, to add ITS_LIVE velocity data to a glacier directory:

from oggm.shop import its_live
its_live.itslive_velocity_to_gdir(gdir)

Below is a brief description of the available datasets. To explore them in practice, see the OGGM as an accelerator tutorial.

If you want more velocity products, feel free to open a new topic on the OGGM issue tracker!

ITS_LIVE#

The ITS_LIVE ice velocity products can be downloaded and reprojected to the glacier directory (visit our tutorials if you are interested!).

The data source used is https://its-live.jpl.nasa.gov/#data Currently the only data downloaded is the v2 120m composite for both (u, v) and their uncertainty. The composite is computed from the 2014 to 2018 average.

Gridded ice thickness#

The Farinotti et al., 2019 ice thickness products can be downloaded and reprojected to the glacier directory (visit our tutorials if you are interested!).

Ice thickness observations#

You can now add observations from the Glacier Thickness Database (GlaThiDa) to your glacier directory with:

from oggm.shop import glathida
glathida.glathida_to_gdir(gdir)

Checkout shop.glathida.glathida_to_gdir().

Millan et al. (2022) ice velocity and thickness products#

Similarly, we provide data from the Millan et al. (2022) global study (visit our tutorials if you are interested!).

Cook et al. (2023) thickness products for the Alps#

Cook et al. (2023) provided a new ice thickness dataset for the Alps. This is now also in the shop, with shop.cook23.cook23_to_gdir().

from oggm.shop import cook23
cook23.cook23_to_gdir(gdir)

Bedmachine ice thickness#

from oggm.shop import bedmachine gives you access to BedMachine Antarctica (v3) and Greenland (v5) for glaciers where these products are available. Refer to the original product pages on NSIDC for reference.
