Descripción
The main goal of this work is to analyse new approaches to the study of
the properties of astronomical sites. In particular, satellite data
measuring aerosols have recently been proposed as a useful technique for
site characterization and searching for new sites to host future very
large telescopes. Nevertheless, these data need to be critically
considered and interpreted in accordance with the spatial resolution and
spectroscopic channels used. In this paper, we have explored and
retrieved measurements from satellites with high spatial and temporal
resolutions and concentrated on channels of astronomical interest. The
selected data sets are the Ozone Monitoring Instrument on board the NASA
Aura satellite and the Moderate Resolution Imaging Spectroradiometer on
board the NASA Terra and Aqua satellites. A comparison of remote-sensing
and in situ techniques is discussed. As a result, we find that aerosol
data provided by satellites up to now are not reliable enough for
aerosol site characterization, and in situ data are required.
