Presencia de la Elegía clásica en El Llanto por Ignacio Sánchez Mejías de Federico García Lorca

En 1935, motivada por la trágica muerte de su amigo torero, Federico García Lorca escribe una de las más bellas composiciones poéticas de la lengua española: el Llanto por Ignacio Sánchez Mejías. Los críticos están de acuerdo en considerarla su obra cumbre: en ella se aúnan y amalgaman los supuestos de su poética con lo más granado de la tradición peninsular, tanto en lo que se refiere la forma como al tema. El género del poema, la elegía funeral, planto o llanto ha sido discutido por los estudiosos de su obra porque a los rasgos propios de la elegía, Lorca sumó los caracteres de la épica y el drama y con ello, sostienen, se alejaría del género clásico. No obstante, creo que el contenido y la estructuración de la obra tiene un estrecho parentesco con el género grecolatino y, sobre todo, con sus variantes hispánicas. El propósito de este trabajo es demostrar el parentesco del Llanto por la muerte de Ignacio Sánchez Mejias con la elegía clásica, a través del estudio de la formación y las características generales de este género.

An integrated instrument package for measuring and understanding the surface radiation budget of sea ice is presented, along with results from its first deployment. The setup simultaneously measures broadband fluxes of upwelling and downwelling terrestrial and solar radiation (four components separately), spectral fluxes of incident and reflected solar radiation, and supporting data such as air temperature and humidity, surface temperature, and location (GPS), in addition to photographing the sky and observed surface during each measurement. The instruments are mounted on a small sled, allowing measurements of the radiation budget to be made at many locations in the study area to see the effect of small-scale surface processes on the large-scale radiation budget. Such observations have many applications, from calibration and validation of remote sensing products to improving our understanding of surface processes that affect atmosphere-snow-ice interactions and drive feedbacks, ultimately leading to the potential to improve climate modelling of ice-covered regions of the ocean. The photographs, spectral data, and other observations allow for improved analysis of the broadband data. An example of this is shown by using the observations made during a partly cloudy day, which show erratic variations due to passing clouds, and creating a careful estimate of what the radiation budget along the observed line would have been under uniform sky conditions, clear or overcast. Other data from the setup's first deployment, in June 2011 on fast ice near Point Barrow, Alaska, are also shown; these illustrate the rapid changes of the radiation budget during a cold period that led to refreezing and new snow well into the melt season.
