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

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

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

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

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

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

, contentious topic!

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

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

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