Hi all,
Given that there has been some recent GLIMS data ingest activity, and that
some people might be referring to data set sizes in AGU abstracts and other
places, I thought I would send an update on some numbers. I include
numbers for the Randolph glacier data set as well for comparison.
The current numbers for GLIMS/RGI are:
GLIMS:
Glacier count: 116000
Glacier area (km2): 523000
RGI:
Glacier count: 170000
Glacier area (km2): 737000
So, at present, GLIMS has about 70% of what RGI has for both glacier count
and area. These numbers are as of about 2 weeks ago, when I added the two
following data sets. There is no reference for these numbers yet (though I
did update the numbers in the GLIMS book Chapter 7 proof).
New data sets ingested this month:
Western Himalaya (northern India), submitted by Holger Frey
Number of glaciers: 11531
Total area (km2): 10867
Arctic Russia, submitted by Max Koenig
Number of glaciers: 1069
Total area (km2): 51592
Total new glaciers: 12600
Total new area (km2): 62459
A few more are pending and I expect to be able to ingest them soon.
Cheers,
Bruce
