The interest in the use of ceilometers for optical aerosol characterization has increased in the last few years. They operate continuously almost unattended and are also much less expensive than lidars; hence, they can be distributed in dense netw

A method for cloud detection and opacity classification based on ground based sky imagery

Autor: M. S. Ghonima, B. Urquhart, C. W. Chow, J. E. Shields, A. Cazorla, J. Kleissl

Publikováno v: Atmospheric Measurement Techniques, Vol 5, Iss 11, Pp 2881-2892 (2012)

Digital images of the sky obtained using a total sky imager (TSI) are classified pixel by pixel into clear sky, optically thin and optically thick clouds. A new classification algorithm was developed that compares the pixel red-blue ratio (RBR) to th

Influence of the calibration on experimental UV index at a midlatitude site, Granada (Spain)

Autor: M. Antón, J. E. Gil, A. Cazorla, J. Fernández-Gálvez, J. M. Vilaplana, F. J. Olmo, L. Alados-Arboledas

Publikováno v: Atmospheric Measurement Techniques, Vol 4, Iss 3, Pp 499-507 (2011)

The ultraviolet index (UVI) is the most commonly used variable to inform about the level and potential harmful effect of ultraviolet (UV) radiation reaching the Earth's surface. This variable is derived from the output signal of UV radiometers applyi

Chiral magnetic phases in Moire bilayers of magnetic dipoles

Autor: Tapia, Ignacio, Cazor, Xavier, Mellado, Paula

Publikováno v: Adv. Phys. Res. 2300135

In magnetic insulators, the sense of rotation of the magnetization is associated with novel phases of matter and exotic transport phenomena. Aimed to find new sources of chiral magnetism rooted in intrinsic fields and geometry, twisted square bilayer
