I have been looking for Mars albedo maps and it is a pain to find them at decent resolution and they are all really outdated.
The easy to find global one is a low resolution one from the MGS TES from before the 2001 duststorm: https://astrogeology.usgs.gov/search/map/Ma...ic_global_7410m There exists a higher resolution albedo dataset from after this duststorm but its in an odd binary format unable to easily be transformed into an image: https://sharad.psi.edu/inertia/2007/albedo.html Then there is the Mars Express one but this one is sadly very hastily put together with holes and seams all over it from the different orbital swaths, dated ten years ago as ESA has seemingly abandoned the mapping of Mars Express imagery a while back. https://www.cosmos.esa.int/web/psa/mars-maps Has anyone had any better luck locating more up to date albedo maps of the red planet? I am specifically looking for one from after the "Oppy killer" dust storm in 2018. -------------------- "Thats no moon... IT'S A TRAP!"

https://astrogeology.usgs.gov/search/map/Ma...ily-Global-Maps are MARCI global maps for the first two Mars years of MRO.
The raw MARCI images are in PDS but I'll admit processing them is probably painful. I got out of that game after MGS. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

Yeah I previously was able to make a cloud map from that database after combining like 9 maps from band 1 at different seasons. Unfortunately with albedo it doesn't work as easily. Hellas keeps appearing as bright as an ice cap in all bands. -------------------- "Thats no moon... IT'S A TRAP!"

Someone was able to get the 2007 binary map converted for me and its only in somewhat better shape than the ESA map given it is at least complete though has many bad passes here and there.

There is also Mars Express Omega NIR albedo map available here.
It hasn't been updated since 2013 and there are coverage gaps, but it has higher resolution than MGS maps. edit: Sorry I was too hasty, the link was already posted. Mods can delete this post. Thank you. |

That is the aforementioned Mars Express map.

i used isis3's dstrip tool and removed some of the stripping on the 26 map
here is a link on my g-drive https://drive.google.com/file/d/1F3Jo_yKJDl...iew?usp=sharing |

Current albedo maps for the purpose of terrestrial visual and photo observations?
Those would be useful. --Bill -------------------- |
