Pendiente y coeficiente de correlación (R 2 ) del ajuste por mínimos cuadrados, desviación absoluta media (MAD) relativa (%) y raíz del error cuadrático medio (RMSE) relativo (%) de la comparación del Índice UV obtenido con el OMI con el obtenido con los instrumentos de suelo para el periodo [2005][2006][2007][2008][2009][2010][2011][2012][2013] Utrillas et al (2013) a nivel de suelo para las estaciones de la Red Radiométrica Nacional de la AEMET durante 10 años de medidas. En todas las estaciones consideradas como costeras por Utrillas et al (2013) se alcanzaron valores del UVI correspondientes a exposiciones altas (6-7) o muy altas (8-10) a la radiación UV en porcentajes similares a los obtenidos aquí (34-46%), mientras que valores del UVI correspondientes a exposiciones extremas (≥11) a la radiación UV se alcanzaron también en muy pocas ocasiones (<0,1%).…”

The erythemal UV daily dose (EDD) and the local noon UV Index (UVI) obtained from the Ozone Monitoring Instrument (OMI), on board NASA’s Aura satellite, have been validated for the period 2005-2013 using ground based measurements at 5 different sites in the Mediterranean coast: Murcia, Valencia, Palma de Mallorca, Barcelona and Rome (where only measurements of the local noon UVI were available). Ground based measurements were made using YES UVB-1 radiometers in Murcia, Valencia, Palma de Mallorca and Barcelona, and a Brewer MKIV 067 spectrophotometer in Rome. The results of the validation showed good agreement between the satellite instrument and the ground based measurements, although the OMI values overestimate the ground based measurements, being the difference between both types of measurements maximum during the spring and summer, and minimum during autumn and winter. The evolution of the EDD shows a clear seasonal behavior for all measuring sites for both, ground based and satellite data, with maximum values in summer (June and July) and minimum values in winter (December and January). A high percentage of cases (>80%) showed minimum differences (0-1 UVI units) between the UVI obtained by OMI and the UVI obtained by ground based instruments for all measuring sites. In every measuring site, high (6-7) or very high (8-10) UVI values are reached for a high percentage of the days of the analyzed period, but very few extreme (≥11) UVI values are reached

“…However, the annual proportion of days with low UVI values increases with increasing latitude. An analysis of 10 years of UVI measurements in Spain (midlatitude region) revealed that the percentage of low UV exposure days ranged from 1% on Gran Canaria up to 37% in A Coruña and Santander . In Barrow, Alaska, a high‐latitude location, low UVI values were exceeded only in the months May‐July of a 21‐year study period .…”

According to the World Health Organization and partner organizations, no protection against ultraviolet (UV) radiation is required on days with "low" values (i.e., values <3) of the Global Solar Ultraviolet Index (UVI). Erythemal irradiance (E er ) data of such days were analyzed to evaluate this claim. Measurements from 9 stations of the German solar UV monitoring network from 2007 to 2016 yielded 14,431 daily E er time series of low UVI days. Erythemal doses for certain fixed time intervals-acquired from measurements on horizontal planes-were compared with the average minimal erythemal dose (MED) of skin phototype II. Doses from days with rounded UVI values of 0 were insufficient to induce erythema and even on days with rounded UVI values of 1 doses exceeding 1 MED of skin type II could only be acquired under very specific circumstances of prolonged exposure. Conversely, sun exposure on days with rounded UVI values of 2 can indeed provide doses sufficient to induce erythema in skin type II after two hours around noon. In conclusion, our analyses do not support the claim of harmlessness currently associated with the entire low UVI exposure category in public guidance on interpretation of the UVI.

We report the case of a senior patient, presenting with two cutaneous tumours in which the clinical and dermoscopic examination pointed towards a basal cell carcinoma. Ultrasound revealed highly vascularised tumours and elastography showed increased rigidity. Histological examination of both lesions following complete resection was consistent with squamous cell carcinomas. The distinctive feature of this case consists of the complex non-invasive diagnostic imaging of the tumour morphology, performed in real time, revealing aspects compatible with highly proliferative malignant tumours. This case emphasises the importance of ultrasound diagnosis in a multi-disciplinary approach for better and more predictable results.
