Regional PIOMAS Volume Data

EDIT - This is a temporary note. I am in the process of substantially improving on the grid box area data which is used to calculate volume. You may want to wait until this note is removed before using this data. However this data produces overall volume accurate to about -0.6% with respect to the main PIOMAS series. This error will be reduced massively as a result of what I am working on now, and the datasets below will be revised and updated within a few days. Chris Reynolds 6/12/13.


I've been busy recently getting the code I use to handle the PIOMAS gridded data into a more tidy state, it was getting the situation where I, the author, was having trouble remembering where the heck I'd coded what. As part of this I've finally dealt with the issue of making a matching set of PIOMAS data broken down into the same regions Cryosphere Today uses.

This post is merely to make the data available to anyone who'll find it useful. I will probably blog before Christmas, including a post on extracting data from the gridded PIOMAS data using Excel, but may not: Work is getting bonkers right now and I need a rest after the work I've put into this, but this blog will shutdown over Christmas and I will be having a rest during that period during the company shutdown.

Peak Selfie

OK, I'm not deluded, I know 'selfies' are here to stay and numbers taken and shared on the 'net will increase, but nobody will ever beat this one, in that way the craze has peaked.

Anyway, it's a mindbogglingly great photo.

October Status

New PIOMAS data is now out for October, I've no intention of continuing with monthly status posts, but will do so when there's something to say. So here's an October's status blog post, and at the end there's a link to my new sea ice spreadsheet.

The 2013 Sea Ice Rebound (that never was)

There was no sea ice rebound in 2013, what happened was variation due to weather, the process underway in the Arctic has not stopped. But the increased volume of 2013 could still be one of the most useful features of the post 2010 situation. In this post I use PIOMAS data both from the PIOMAS main volume series, and PIOMAS gridded data, also Cryosphere Today Area (CT Area) and NSIDC Extent.

European Precipitation and Sea Ice Loss

James Screen has released a lot of important papers on Arctic sea ice loss and the atmosphere, he's done it again, in "Influence of Arctic sea ice on European summer precipitation.", not paywalled.

I'm particularly excited about this because it goes some way to supporting something I've been going on about for two years now. I should point out at the outset - it is very unlikely that Dr Screen is aware of my persistent blogging on this subject!

Winter warming and sea ice thinning.

Arctic Amplification is the tendency of the Arctic region to warm more than the global average with Global Warming. While it is an effect initially seen in modelling studies it has been recently found to be emerging from natural variability. I have used PIOMAS gridded sea ice thickness data and NCEP/NCAR atmospheric temperature data to examine the connection between sea ice thinning and winter warming.

Mid Monthly Miscellenea: October.

The time has come, the Walrus said, to talk of many things...
