Difference in glacierized area between gridded and vector data product for RGI regions 14 and 15.

[yoniv1]

RGI version RGI v6.0

Describe the issue I have downloaded the RGI6.0 data, both the vector product and gridded data, from the C3S climate data store and calculated the total glacierized area per RGI region. The vector and raster data correspond well to one another, except for RGI regions 14 and 15. Maybe something went wrong here? I doubt that there would be an error in my code, cause the other regions seem to fit well with one another.

Expected outcome Maybe it can be checked?

Suggested solution Check the glacierized area of the gridded dataset with the one from the vector product for RGI regions 14 and 15.

Thanks for the report! This has been documented before:

https://www.cambridge.org/core/journals/journal-of-glaciology/article/new-global-gridded-glacier-dataset-based-on-the-randolph-glacier-inventory-version-60/621E15FFA80C8B0612146022A7197AC5

You'll find access to updated datasets there.

RGI 7.0 does not currently offer gridded products, but it would be relatively easy to add.

Hi, thanks for the answer! I'm just wondering if there is a specific reason why this mismatch occurs in Himalayan regions in this data version?

Kind regards, Yoni

I'm not sure - I wasn't responsible for RGI6 data production, but perhaps the wrong shapefiles were used? We will probably never know.
