I was wondering to what surface that reflectance curve belongs?

It is definetely no water or snow since their reflectance drops at a much smaller wavelength.

I was thinking about a dense cloud but the decrease seems to be too constant.

Has anybody an idea what it could be?

  • Strange that it doesn't have the water absorption "dips". Any hints on where it came from? – BradHards Nov 26 '14 at 9:37
  • Nope, its a part of an exercise where I could easily assign all the respective curves, thats the only one where I have no clue. – Daniel Nov 26 '14 at 10:03
  • its something white – nickves Nov 26 '14 at 10:15
  • @nickves It definitely is – Daniel Nov 26 '14 at 10:36
  • Any idea on what type of remotely sensed data this spectral signature was derived from (e.g. satellite imagery, hand-held spectrometer)? I am not seeing any absorption bands, so data was probably acquired on the ground. My guess is snow of some sort. – Aaron Nov 26 '14 at 12:59

I don't know for what object this particular spectral signature ties at but i can suggest to browse a spectral library for something that is close match.



I'm almost sure that it must be some kind of cloud, since its the only object that I could find that declines in such a constant way after peaking at the visible wavelength spectrum. Thx for the help :)


Spectral reflectance curve is the graphical representation of spatial response of an object on different wavelengths of electromagnetic spectrum
