NASA Cold Land Processes Experiment (CLPX 2002/03): ground-based and near-surface meteorological observations

A short-term meteorological database has been developed for the Cold Land Processes Experiment (CLPX). This database includes meteorological observations from stations designed and deployed exclusively for CLPXas well as observations available from other sources located in the small regional study area (SRSA) in north-central Colorado. The measured weather parameters include air temperature, relative humidity, wind speed and direction, barometric pressure, short- and long-wave radiation, leaf wetness, snow depth, snow water content, snow and surface temperatures, volumetric soil-moisture content, soil temperature, precipitation, water vapor flux, carbon dioxide flux, and soil heat flux. The CLPX weather stations include 10 main meteorological towers, 1 tower within each of the nine intensive study areas (ISA) and one near the local scale observation site (LSOS); and 36 simplified towers, with one tower at each of the four corners of each of the nine ISAs, which measured a reduced set of parameters. An eddy covariance system within the North Park mesocell study area (MSA) collected a variety of additional parameters beyond the 10 standard CLPX tower components. Additional meteorological observations come from a variety of existing networks maintained by the U.S. Forest Service, U.S. Geological Survey, Natural Resource Conservation Service, and the Institute of Arctic and Alpine Research. Temporal coverage varies from station to station, but it is most concentrated during the 2002/ 03 winter season. These data are useful in local meteorological energy balance research and for model development and testing. These data can be accessed through the National Snow and Ice Data Center Web site

British Romanticism and the Global Climate

As a result of developments in the meteorological and geological sciences, the Romantic period saw the gradual emergence of attempts to understand the climate as a dynamic global system that could potentially be affected by human activity. This chapter examines textual responses to climate disruption cause by the Laki eruption of 1783 and the Tambora eruption of 1815. During the Laki haze, writers such as Horace Walpole, Gilbert White, and William Cowper found in Milton a powerful way of understanding the entanglements of culture and climate at a time of national and global crisis. Apocalyptic discourse continued to resonate during the Tambora crisis, as is evident in eyewitness accounts of the eruption, in the utopian predictions of John Barrow and Eleanor Anne Porden, and in the grim speculations of Byron’s ‘Darkness’. Romantic writing offers a powerful analogue for thinking about climate change in the Anthropocene

Does Including Soil Moisture Observations Improve Operational Streamflow Forecasts in Snow-Dominated Watersheds?

Changing climate and growing water demand are increasing the need for robust streamflow forecasts in the Western U.S. Historically, operational streamflow forecasts made by the Natural Resources Conservation Service (NRCS) have relied on precipitation and snow water equivalent (SWE) observations from Snow Telemetry (SNOTEL) sites. In this study, we investigate whether also including SNOTEL soil moisture observations improve April-July streamflow volume forecast accuracy at 0, 1, 2, and 3 month lead times at 12 watersheds in Utah and California. We found significant improvement in 0 and 3-month lead time accuracy in 8 of 12 watersheds and 10 of 12 watersheds for 1 and 2-month lead times. Surprisingly, these improvements were insensitive to metrics derived from soil physical properties. For consistency and simplicity, forecasts were made with volumetric water content (VWC) averaged from October 1 to the forecast date. Including VWC at the 0-month lead time forecasts explained 7.3% more variability and increased the streamflow volume accuracy by 8.4% compared to standard forecasts that already explained 77% of the streamflow variability on average. At 1 to 3-month lead times, the inclusion of soil moisture explained 12.3% to 26.3% more variability than the standard forecast. Our findings indicate that including soil moisture observations into statistical streamflow forecasts can increase water supply reliability in arid regions affected by changing snowpacks

The Rise of the Climate Change Novel

This chapter outlines the emergence of climate fiction and its key modes. It pays particular attention to the extent to which climate fiction has worked within the established conventions of literary realism, meeting the many representational challenges mounted by climate change. While it considers the extent to which realism is able to render the abstract and intangible phenomenon of climate change visible, it argues that there is also a significant body of writing on the subject which turns to alternative forms and narrative strategies in the effort to represent climate change, and manages to overcome some of the limitations of realism. In other words, where climate fiction meets the challenges of representing climate change, it has the potential to provide a space in which to address the Anthropocene’s emotional, ethical, and practical concerns

Evaluation of forest snow processes models (SnowMIP2)

Thirty‐three snowpack models of varying complexity and purpose were evaluated across a wide range of hydrometeorological and forest canopy conditions at five Northern Hemisphere locations, for up to two winter snow seasons. Modeled estimates of snow water equivalent (SWE) or depth were compared to observations at forest and open sites at each location. Precipitation phase and duration of above‐freezing air temperatures are shown to be major influences on divergence and convergence of modeled estimates of the subcanopy snowpack. When models are considered collectively at all locations, comparisons with observations show that it is harder to model SWE at forested sites than open sites. There is no universal “best” model for all sites or locations, but comparison of the consistency of individual model performances relative to one another at different sites shows that there is less consistency at forest sites than open sites, and even less consistency between forest and open sites in the same year. A good performance by a model at a forest site is therefore unlikely to mean a good model performance by the same model at an open site (and vice versa). Calibration of models at forest sites provides lower errors than uncalibrated models at three out of four locations. However, benefits of calibration do not translate to subsequent years, and benefits gained by models calibrated for forest snow processes are not translated to open conditions

Climate and History in the Anthropocene: Realist Narrative and the Framing of Time

This chapter is prompted by recent calls by historians and other scholars for new understandings of history in the Anthropocene; it asks what this might mean for literary realism, invested as it is in the depiction of the passing of time. History in the Anthropocene renders redundant the human-historical, individual-universal dialectic that has long been the hallmark of the realist novel. Following Ian Baucom, this chapter looks to Walter Benjamin’s conceptualisation of history for clues to a new form of literary realism. For Benjamin, a true understanding of history demands the recognition of the 'image' of history, a recognition occurring in a moment of 'arrest' or stoppage in the flow of time and of thought. This chapter speculates on the emergence in the Anthropocene of a literary realism that performs just such an arrest, taking its reader beyond conventional understandings of (human) history and time

Ethereal women: Climate and gender from realism to the modernist novel

This chapter examines Charlotte Brontë’s Villette (1853), Dorothy Richardson’s Pilgrimage (1915–1938) and selections of non-fiction writing by Virginia Woolf published between 1919 and 1925. It argues that the fluid psychology we traditionally associate with twentieth-century experiments in literary form begins with the impact of nineteenth-century climate science on realist fiction. The atmospheric modes of female consciousness and ethereal embodiment that women’s presumed sensitivity to climate engenders in novels like Jane Eyre and Bleak House, thus give rise to later, feminist engagements with female authorship such as Richardson’s and Woolf’s. Taking May Sinclair’s pioneering use of the term ‘stream of consciousness’ to describe Pilgrimage in 1918 as a pivot point, the essay connects Richardson’s acknowledged debt to Villette with the climatic underpinnings that inform Woolf’s responses to both of these novels as well as her famous definition of modern fiction as ‘an incessant shower of innumerable atoms’
