At what distance is the planet located, and with what kind of telescope?
Over many orbits, the cloud cover of an exoplanet will vary. How do you differentiate this change from different surface features?
its got to be all about what portion of the spectra and polarization changes
I have a similar question to Jill’s: how robust/sensitive is this technique to the variability of albedo; for instance in the case of periodic or episodic phenomena/variabilities.
Also finding the solution to the photometric variations/modulations is usually an ill-posed problem and the solution is usually not unique. How the best solution is being selected in these cases?
What are your IRVBU wavelength ranges?
Also please note the observations like this we did with the Deep Impact s/c looking at the Earth. we clearly saw variations on the earth with clouds, land, oceans, AND we observed what happened when the Moon eclipsed the earth..
This link might be useful for starters on the problem - Enric Palle identified how long you would need to observe an Earth to identify continents versus cloud coverage - he found you need observations every 2 hours.
How sensitive are the solutions to a precisely known rotation period?

I was going to say Livengood et al. 2011. Thanks Jim !
