After having become quite good friends with #GIMP, I've decided to give it a shot with #Inkscape today. My first "creation" is a sketch of the staggered Arakawa C grid for the #SICOPOLIS user manual (https://sicopolis.readthedocs.io/en/develop/).

Our new article in the Journal of Glaciology has been published online:

"Future projections for the Antarctic ice sheet until the year 2300 with a climate-index method" by Ralf Greve, Christopher Chambers, Takashi Obase, Fuyuki Saito, Wing-Le Chan, Ayako Abe-Ouchi.

Check out the new user manual for the ice-sheet model #SICOPOLIS. A great shout-out to Shreyas Gaikwad for having set up the framework for it and writing the part pertinent to #AutomaticDifferentiation!

We published the dataset for our preprint "Future projections for the #AntarcticIceSheet until the year 2300 with a climate-index method" on #Zenodo:
https://doi.org/10.5281/zenodo.7773727.

Preprint @ #EarthArXiv, https://doi.org/10.31223/X5F06Q (submitted to the Journal of Glaciology).

My old theses, both done at #TUDarmstadt (in German), are both available on #Zenodo:

Diploma thesis 1991:
Zur Ausbreitung einer Granulatlawine entlang gekrümmter Flächen - Laborexperimente und Modellrechnungen
https://doi.org/10.5281/zenodo.3768623
(on granular avalanches)

Doctoral thesis 1995:
Thermomechanisches Verhalten polythermer Eisschilde - Theorie, Analytik, Numerik
https://doi.org/10.5281/zenodo.3775042
(on polythermal ice sheets - birth of the ice-sheet model #SICOPOLIS)

Our paper has just been published in the Journal of Open Source Software:

"SICOPOLIS-AD v2: tangent linear and adjoint modeling framework for ice sheet modeling enabled by automatic differentiation tool Tapenade".

I'll present our work on "Reduced mass loss from the #GreenlandIceSheet under stratospheric aerosol injection" tomorrow 8 March, 15:15-15:35 JST at the Seventh International Symposium on Arctic Research (ISAR-7 https://www.jcar.org/isar-7/, session R4 "Ice Sheets, Glaciers and Ice Cores").

#Geoengineering, contentious topic!

#AGU22 meeting next week. Sure it would be more exciting to go in person, but for the sake of #ClimateProtection I'll save the >20,000 flight kilometres and attend online. I'll present our work on simulations of the #Antarctic ice sheet until 2300 CE with the #SICOPOLIS model, carried out for #ISMIP6 (https://agu.confex.com/agu/fm22/meetingapp.cgi/Paper/1103423).

#30DayMapChallenge Day 25: Colour Friday: 2 colours
Water layer thickness under the present-day #Antarctic #IceSheet simulated with a steady-state routing scheme for subglacial water, which is part of the hydrology module of the ice-sheet model #SICOPOLIS. Plotted with #MATLAB in shades of blue and red. As a compromise between lin and log, I employed a 4th-root scaling.

Today I presented at the #NIPR Symposium on #PolarScience: "Dependence of the future mass loss of the #AntarcticIceSheet on climate forcing and ice-shelf disintegration". This is our group's contribution to the #ISMIP6 Projections 2300 Antarctica (https://tinyurl.com/ismip6-ais-2300) with the #SICOPOLIS model.
