Title: PIOMAS gridded thickness and regional volume
Post by: Jim Hunt on June 14, 2017, 11:14:04 AM
Many moons ago Chris Reynolds produced regular updates of PIOMAS regional volume derived from the gridded thickness data. Here's the most recent example:

(https://forum.arctic-sea-ice.net/proxy.php?request=http%3A%2F%2Fforum.arctic-sea-ice.net%2Findex.php%3Faction%3Ddlattach%3Btopic%3D119.0%3Battach%3D46649%3Bimage&hash=a8279c233b7f85d7b7f87890b88022d9)

and here's his explanatory article:

There seems to be a lot of renewed interest in such data, so can we pick things up where Chris left off?

Rob Dekker asks:

Jim, did Chris Reynolds define the various 'seas' anywhere ?


To which the answer is yes. See Chris's article above and the associated data at:

My first thought was to start from Zack Labe's public domain PIOMAS python code available at:

https://github.com/zmlabe/SeaIceThickness (https://github.com/zmlabe/SeaIceThickness)

Zack's currently away from his office at a conference in Colorado, but has kindly agreed to provide the missing "grids.txt" file on his return.

Does anybody else have any other suggestions?

As I was setting up this thread the wondrous Wipneus was delivering the data. See:
