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.

El presente trabajo se propone analizar la representación de la ciudad de México que construye José Joaquín Fernández de Lizardi en su periódico El Pensador Mexicano (1812-1814) como contracara de la ciudad letrada (Rama, 1984) y el arcano (Palti, 2005). El objetivo es examinar las descripciones de esta ciudad (sus características, recorridos y recovecos) como indicios y huellas de los cambios que acontecen en el contexto político, social y económico propios de un sistema colonial en decadencia. Para ello, se abordarán escenas y diálogos del periódico tendientes a construir una mirada "descarnada" y "polifónica" sobre la forma de vida en dicho espacio urbano en vistas a ser interpretada a través de distintas categorías de análisis como son las de "vecino/ciudadano" (Guerra, 1999); "Ciudad burguesa criolla" (Romero,2001); "ciudad escrituraria/ ciudad real" (Rama, 1984), "ciudades invisibles" (Calvino,1972) y "secularización literaria" (Foffani, 2010). Estas categorías dialogarán con la perspectiva particular de Fernández de Lizardi como "publicista" (Palti, 2005) y "predicador caústico" (Palazón Mayoral, 2006) dentro de un espacio discursivo nuevo que se va configurando como es el de la opinión pública concebida como modelo jurídico y reino de transparencia
