A radiation model was developed for retrieving cloud visible optical depth,
droplet effective radius, and cloud top emission temperature using AVHRR satellite
observations at 0.63, 3.7, and 11 μm. The model was used to determine the sensitivity
of the retrieved properties to various approximations often employed in such retrievals.

Air trapped in glacial ice offers a means of
reconstructing variations in the concentrations of atmospheric
gases over time scales ranging from anthropogenic
(last 200 yr) to glacial/interglacial (hundreds of thousands of
years). In this paper, we review the glaciological processes by
which air is trapped in the ice and...
