This Thesis work has been developed thanks to a pre-doctoral
scholarship (FI) from the Ministry of Universities, Research and
Information Society (DURSI) of the Government of Catalonia.
This work has been partly funded through projects IMMPACTE from
the Ministry of Environment of the Government of Catalonia, and
DEPRUVISE (REN2000-0903-C08-01/CLI) from the Ministry of Science
and Technology of the Government of Spain.
Part of the work, mainly the Chapter 5, followed on from a three-
month research stay in 2002 of the author at the Royal Netherlands
Meteorological Institute (KNMI) at De Bilt, The Netherlands, under the
supervision of Dr. Michiel van Weele.
Most of the studies presented have been partly developed during
research stays of the author at the National Institute of Water and
Atmospheric Research (NIWA) at Lauder, New Zealand, in 2003 (three
months) and 2004 (four months and a half). For this, we feel very grateful
with Dr. Richard McKenzie, who supervised those stays; his trust,
enthusiasm and guidance in this work are very much appreciated.
All the individuals and institutions listed in Table 4.2 are gratefully
acknowledged for the supply and support of the data used in Chapter 4.
I would also like to thank Dr. Chuck Long of Pacific Northwest
National Laboratory (Richland, WA, USA) for the kind assistance in the
use of the software for the clear sky selection process presented in
Chapter 4.
I would also like to thank Alexander Los from Kipp & Zonen for his
kind dedication and efforts in the characterisation of the erythemal
radiometer installed in Girona.

I also want to specially thank Josep Calbó and Josep Abel González
for the opportunity of undertaken this PhD Thesis, for the support,
guidance, trust and understanding during these almost 5 years of working
together.
There would be many other names worth mentioning here. I just hope
I have been able to show my sincere gratitude because a part of this
Thesis belongs to them, and it wouldn’t be like this without them.
