Author Merikanto

CO2 1200, current orbital parameters.

Gnetated with scripts, Krita HDV etc edit

Exoplasim very basic params.

a_eccentricity1=0.0167022 a_obliquity1=23.441 a_lonvernaleq1=102.7 a_pCO21=1200.0e-6

Simulated with Exoplasim. Map created with Koppenpasta, Imagemagick, Freds "emboss" script and sometimes also Krita. Used Scotese 1 min Paleodem to make Exoplasim simulation and 6 min PaleoDEM to visualize. Operating system ubuntu etc. to run script.

"lang.png" and "sea.png" uses scaling factor 25, that produces 1600x800 map

"koppen.png" uses scaling factor 1
