The ICCARS Spectrum Guide was created to accompany a kit of materials available to be checked out by teachers who participated in the ICCARS program. The Investigating Climate Change and Remote Sensing (ICCARS) Project is intended to give students and teachers a working understanding of the science behind global climate change and its relationship to human activity, in particular its relationship to land-use and land-cover changes on multiple scales, through use of NASA data products and models.
