Abstract
The use of satellite data in applications has changed as the environmental
community has become more sophisticated deriving products from the remotely
sensed measurements. This introduction summarizes the changes from the first
satellites where the images were used to improve cloud forecasts to the international
coordination groups that have formed to improve collaboration and data sharing of
satellite observations. This introduction also addresses some of the key challenges
associated with using satellite data for both weather and climate; the challenges
include calibration, derived products, trend uncertainty, and measurement quality.
A short discussion of subsequent future issues is briefly discussed as satellite mea-
surement calibration reaches maturity.
