*Why we need huge datasets of space-based Earth observations, examples of

how an involved statistician might help out*

From a human perspective, Earth is a huge planet, and environmental
conditions are enormously diverse. Yet we care very much about even
small-scale and short-lived phenomena, as they affect climate and determine
habitability.  As such, satellite-borne instruments that can make frequent,
global observations are central to our study of current conditions, and are
indispensable for efforts to predict future change.  As a window into the
nature of massive Earth science data sets, I will use space-based
measurements of aerosols: desert dust, volcanic ash, wildfire smoke, and
pollution particles.  The environmental context for these measurements,
general data set attributes, key questions these data are intended to
address, and the need for coupling such observations with climate and air
quality numerical models, will be covered.  The final aspect of the
seminar, how statisticians might help out, will be explored during
discussion at the end of the presentation.
