It is widely known that the Earth system undergoes change due to human influence. However, how can one estimate the extent of change without an adequate knowledge of the actual pre-industrial atmospheric chemistry of the planet and, then, infer the differences?
The NASA Applied Remote Sensing Training Program (ARSET) develops courses for end-users on the application of satellite data and imagery to environmental decision-making activities related to water resources, air quality, and disaster management. ARSET makes course materials publicly available and actively encourages their use by environmental managers or others interested in developing their own applied remote sensing courses.
Growing awareness of the deficiencies of todayÛªs greenhouse gas inventories is inspiring innovation by scientists, policymakers and activists. There is growing hope for ÛÏtop-downÛ schemes based on rapid and even real-time measurement of atmospheric greenhouse gases. Now the push is on to install ground and satellite-based instruments.
