[GLIMS] Numbers for recent GLIMS ingests

[Bruce RAUP]

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
