Archived mosaic images are available online and images for every hour of the year, for the years 2000 to the present, are downloaded and encoded into a series of HD video animations, one per year. By presenting each hour of the year as one video frame, the entire year is collapsed into a run-time of just under five minutes. One can perceive seasonal storm patterns and perhaps detect longer-term climate changes.

I am interested in the landscape sublime and how it might be manifested through contemporary environmental sensing and imaging systems. Since initial descriptions of the sublime by Burke and Kant, intense weather and storms have been considered to belong to the realm of the sublime. Nineteenth century landscape painters often attempted to capture the sublime in the landscape as manifested by powerful storms, perhaps most notably by Turner. In the nineteenth and twentieth century, as urbanity expanded, humanity became desensitized to the landscape sublime as it was superseded by the technological sublime. Now, with environmental catastrophe threatening, the landscape sublime has begun to reemerge in our consciousness. In this work I seek to provide a modern technological window into the landscape sublime.
Of course it is impossible to discuss the landscape and weather without invoking the specter of climate change. It is natural to attempt to perceive some evidence of climate intensification as one views year after year of weather, all compressed into a few minutes. These videos might be expected to provide a palpable experience of climate change. In fact, detecting such change in them seems difficult, longterm trends being lost in the chaos of short-term weather patterns. Detecting long-term change becomes difficult. The videos provide an experience of the complexity which climate scientists must deal with.
