Summary
Abstract: In English:

The works were carried out in the Marambio, Ushuaia and Belgrano stations with
the radiometers NILU-UV and they consisted in:

-It has been carried out an exhaustive control of quality of the radiometer
NILU-UV net to assure the use of radiation UV measures obtained by this net to
approach studies of tendencies in the next years.

-It improved the system of calibration of the radiometers NILU-UV, which
conform the RACRUV net, introducing a calibration system with external lamps
that it supplements and improve the current system of lamps implanted
previously.

-An external system of quality system has also been settled down in the RACRUV
net by means of the introduction of a NILU-UV radiometer of traveller reference
that it carries out calibrations in situ in those stations of annual character.

-They have been improved the algorithms that allow to obtain the ozone and
optic thickness of clouds by means of ghastly measures with the NILU-UV
radiometers.

-Bigger knowledge have been obtained on the determination of the coefficients
of NILU-UV calibration using different reference spectrometers and calculating
this coefficients in different locations with very different atmospheric
conditions.

-They have improved the algorithms for the determination of ozone and optic
thickness of clouds with the NILU-UV radiometers using models of radiative
transfer and teledetection tools that allow to standardize advisably the
aerosols and clouds.

-The ozone data obtained with the NILU-UV radiometers have been compared with
those obtained with EVA spectrometers, TOMS and different spectrophotometers
installed in each one of the stations.

-They have been determined and analyzed the evolution go the spectral
ultraviolet radiation during the polar vortex episodes.

-A principle of validation of the extraction algorithms has settled down of
microphysics parameters of clouds.

Los trabajos se realizaron en las estaciones de Marambio, Ushuaia y elgrano con
los radiometros NILU-UV y consistieron en:

-Se ha realizado un exhaustivo control de calidad de la red de radiometro
NILU-UV para asegurar la utilizacion de las medidas de radiacion UV obtenidos
por esta red para abordar estudios de tendencias en los proximos años.

-Se mejoro el sistema de calibracion de los radiometros NILU-UV que conforman
la red RACRUV introduciendo un sistema de calibracion con lamparas externas que
complemente y mejore el actual sistema de lamparas implantado anteriormente.

-Ademas se ha establecido un sistema externo de control de calidad en la red
RACRUV
mediante la introduccion de un radiometro NILU-UV de referencia viajero que
realice calibraciones in situ en las estaciones de caracter anual.

-Se han mejorado los algoritmos que permiten obtener el ozono y espesor optico
de nubes mediante medidas espectrales con los radiometros NILU-UV.

-Se han obtenido mayores conocimientos sobre la determinacion de los
coeficientes de calibracion de los NILU-UV utilizando diferentes espectrometros
de referencia y calculando dichos coeficientes en diferentes emplazamientos con
condiciones atmosfericas muy diferentes.

-Se han mejorado los algoritmos para la determinacion de ozono y espesor optico
de nubes con los radiometros NIL-UV utilizando modelos de transferencia
radiativa y herramientas de teledeteccion que permiten parametrizar
convenientemente los aerosoles y las nubes.

-Se han comparado los datos de ozono obtenidos con los radiometros NILU-UV con
los obtenidos con los espectrometros EVA, por el TOMS y por los diferentes
espectrofotometros instalados en cada una de las estaciones.

-Se han determinado y analizado la evolucion de la radiacion ultravioleta
espectral durante los episodios de vortice polar.

-Se ha establecido un principio de validacion de los algoritmos de extraccion
de parametros microfisicos de nubes.
