No full textThe idea to held the first International Summer School on Atmospheric
and Oceanic Sciences (ISSAOS) in L’Aquila was a sort of coupe de foudre
during a Spring warm day. Nothing romantic, of course, but simply timely:
during an unexpected discussion we realized, on one hand, the emergence
of a larger and larger remote sensing activity at the University of L’Aquila
and, on the other hand, the national academic interest to start a cycle of
International Summer Schools on atmospheric and oceanic physics. The
basic ingredients were soon identified: a topic of general scientific interests,
a high quality selection of lecturers and, last but not least, a pleasant venue.
ISSAOS-2000 was in the period September 4-8 at the College of
Engineering of the University of L’Aquila, amazingly placed on a hill at
about 1000 m. The city of L’Aquila offered the historical landscape of five
days of full immersion. More than 70 students responded to the call and
agreed to follow more than 35 hours of lectures. The conclusive social
dinner, amused by spontaneous music, was the deserved prize for all
participants and organizers.
The primary audience of ISSAOS-2000 was constituted by graduate
students in remote sensing and geosciences, Ph.D. or equivalent students,
remote sensing researchers specialist in one single field, willing to have a
basic understanding of spaceborne remote sensing capabilities for
atmospheric and ocean remote sensing with current established techniques
and a research perspective.
This book is essentially the collection of the lectures, given during
ISSAOS-2000 by the lecturers coming both from Europe and USA. Its goal
is to provide a broad panorama of spaceborne remote sensing techniques, at
both microwave and visible-infrared bands and by both active and passive
sensors, for the retrieval of atmospheric and oceanic parameters. A
significant emphasis is given to the physical modelling background,
instrument potential and limitations, inversion methods and applications.
Topics on international remote sensing programs and assimilation techniques into numerical weather forecast models are also touched in the
last chapter.
Since the main purpose of this book is to offer a well selected
introductory material, each contribution is maintained within a limited
number of pages, giving emphasis to the basic concepts and to an
appropriate and abundant list of references. Even though this book is
published after almost two years with respect to the end of ISSAOS-2000,
we believe it represents a valuable sample of the state-of-the art on remote
sensing of the atmosphere and ocean. In this regard, on January 2002 we
asked the contributors to include up-to-date concepts and references within
their sections.
As mentioned before, the organization of an International Summer
School is a complex task, especially at its first edition. We acknowledge the
financial contribution to ISSAOS-2000 coming from: the Italian Space
Agency (ASI), the Science and Technology Park of Abruzzo (PSTd’A), the
IEEE Geoscience and Remote Sensing Society – Central and South Italy
Chapter, the Department of Electrical Engineering and the Department of
Physics of the University of L’Aquila, the Italian Remote Sensing
Association (AIT) and the Italian Inter-University Centre for Atmosphere
and Hydrophere Physics (CIRFAI). We are also grateful to the Dean of the
College of Engineering of the University of L’Aquila for the use of rooms
and facilities.
The first personal acknowledgment goes to Simona Zoffoli of the Italian
Space Agency (ASI) who enthusiastically supported the ISSAOS-2000
idea. Errico Picciotti, Tonia Fortunato, Adelaide Memmo and Fabrizio
Mancini were irreplaceable for their support and continuous availability
before and during ISSAOS-2000. A further acknowledgment is due to
Ortensia Ferella, Pierlugi Strinella and Daniele Masoni of the International
Science Services who have made available all their professionalism for the
organization of the meeting. A very dedicated and warm acknowledgment
goes to Simona Marinangeli, responsible for the editorial format of this
manuscript: her effective and efficient work has made this hopefully
important publication possible
Climate Change and atmospheric composition research via baloons
No full textA brief description of a compact, high sensitive and selective fluorescence technique
for the atmospheric composition measurements is given here. This technique that uses
a laser as a source has been used at the beginning on balloon platforms, in the last years it
is preferred to use an aircraft as flying platform because it allows the measurements of atmospheric
species not only as function of the altitude, but also the study of the variation
from region to region. A short description of the instrument developed at the CETEMPSUniversit`
a di L’Aquila, some results and future improvements and deployment will be also
reported
