Snow Measurement Field School January 2022

January 2 - 7, 2022 / 10:00 AM - 4:00 PM ET


Location: Wanship, Utah


Snow covers a large portion of the Earth’s mid- and high-latitude land surface for extended periods every year. The snow that accumulates in mountains and forests is a crucial resource, providing melt water to about 2 billion people on Earth (Mankin et al., 2015). Snow also regulates essential climate processes through the snow albedo effect (Kellogg, 1973; Groisman et al., 1994; Lemke et al., 2007) and through its superb insulating properties (Goodrich, 1982; Mellor, 1964; Sturm et al., 1997). Quite simply, any change in global snow quality or quantity is likely to have serious climatic societal consequences for all of us (Barnett et al., 2005; Mankin et al., 2015; NASA, 2016).

Accurate snowpack property measurements are needed as ground truth for remotely sensed data, as input for hydrological models, as input to ecological models, and as data when making avalanche forecasts.

This course provides hands- on training and experience with snow measurements, to help directly with snow measurement research objectives and for interpreting snow measurements collected by others.

The curriculum assumes little prior knowledge and experience on the part of the students, and begins with field and snow safety, then progresses to simple but critical snow measurements like depth, density, and snow water equivalent. Students are divided into teams and paired with an instructor then tasked with making field measurements that simulate what would be required in actual field campaigns. Daylight hours are spent almost entirely out in the snow, but in the evenings students work collectively to analyze and reflect on the day's measurements, and listen to lectures about field measurements, sampling design, handling of data, and more advanced measurement topics.

Course Objective:

This course will give fundamental training to students in making and analyzing snow measurements including depth, density, water equivalence, grain size and shape, stratigraphy, temperature and hardness. Students completing this course will be able to perform high-quality fieldwork and design studies making snowpack measurements.

Learning Objectives:

By the end of the course, students should be able to do the following:

  • Excavate and prepare a snow pit.
  • Measure profiles of density, snow temperature, grain size, and hardness.
  • Characterize stratigraphy and layering, snow surface roughness, and snow grain types.
  • Use a Federal snow sampler, an avalanche probe, a Magnaprobe, and other snow measurement equipment.
  • Design their own experiment for sampling snow based on specific scientific objectives.

Workshop Eligibility and Requirements:

The course is aimed at graduate students, post-docs, professionals and senior scientists, modelers and remote sensors that will make snow measurements as part of their research, or use snowpack data in their research. Priority will be given to graduate students and early career researchers but undergraduates may participate pending availability.

There are no required prerequisites, but students should be physically able to spend days outside being active in the snow.

COVID Considerations:

CUAHSI is closely monitoring guidance from the CDC and other health authorities to ensure a safe experience for all participants. CUAHSI expects that only fully vaccinated people will attend the Snow Measurement Field School. Further guidance regarding health and safety measures for this event is forthcoming.

If conditions and advice dictate, CUAHSI reserves the right to cancel or reschedule this workshop.
