Anne Nolin and PhD student, Travis Roth, attended and presented at the NASA SnowEx meeting in Longmont, Colorado August 8-10, 2017.

SnowEx is a multi-year ground-based and airborne snow campaign funded by NASA’s Terrestrial Hydrology Program. The first SnowEx field campaign was held in February 2017 on Grand Mesa and Senator Beck Basin in western Colorado.

SnowEx investigators and their students presented on results relating to this campaign and to the SnowEx goals in general.

Nolin’s presentation was entitled” Post-wildfire summer greening depends on the previous winter’s snowpack” in which she highlighted the work of MS student Andy Wilson. Preliminary results suggest that antecedent snowcover affects post-fire summer greening. The relationship between snow and summer greening appears to be influenced by soils, land cover, and burn severity but we need to examine many more fires, additional variables within a rigorous statistical framework.

It is with a mixture of enthusiasm and sadness that I announce my decision to depart OSU for an exciting new position as Director of the Graduate Program of Hydrologic Sciences (GPHS, http://www.hydro.unr.edu/) at the University of Nevada-Reno (UNR).  I will remain at OSU through this academic year with my new position starting on July 1, 2018.

I have greatly enjoyed my time in OSU’s Geography program since 2003.  At UNR, my research will continue to focus on snow hydrology, climate forcings on mountain snowpacks, glaciers, and meltwater, mountains as social-ecological systems, and remote sensing of snow and ice.   I will continue to advise graduate students and, starting in 2020, will return to teaching.

As part of their NASA ABoVE project studying the effects of changing snowpacks on Dall sheep, Nolin and Cosgrove spent a week in Alaska mapping snow depth and digging shallow snow pits to characterize snow in the Wrangells Mountains near Nabesna, AK.

On April 23-27, the Mountain Sentinels group hosted a workshop entitled “Transdisciplinary Modeling of Mountain Social-Ecological Systems” at Rock Springs Ranch in Bend, Oregon. Chaired by Anne Nolin, Julia Klein, Catherine Tucker, and Robin Reid, the workshop brought together 22 participants representing participatory research across 15+ mountain regions on five continents.

The broader objectives this workshop were to explore and evaluate transdisciplinary modeling frameworks for mountains, to identify relevant questions and scenarios to explore with models, and to conduct synthesis modeling across mountain sites worldwide using fit-for-purpose modeling approaches.

PhD student Chris Cosgrove has been awarded a small grant from the American Alpine Club to develop miniaturized automated weather information in snowy mountain regions. The grant, entitled ‘SnowBot’: an open-source automated weather station for wireless sensor networks in high altitude/latitude environments provides $750 in funding for Chris to develop tiny monitoring stations which will be deployed in the Oregon Cascades and the Alaskan Wrangells mountains. Assistant Professor Bo Zhao (OSU Geography) is helping Chris in this effort. Go Chris!

Nolin has been added to the NASA SnowEx Science Definition Team and has received five years of funding to support this effort.
The SnowEx project (https://snow.nasa.gov/snowex) is a multi-year airborne snow campaign focusing on accurate estimates of water is stored in Earth’s terrestrial snow-covered regions.

In this capacity, Nolin and her students will achieve the following specific objectives:

  1. Evaluate forest structure metrics that affect snow remote sensing, from forest stand to watershed to larger scales;
  2. Improve and validate model parameterizations of forest effects on snow characteristics: including forest structure and forest litter (the direct effect of forest litter on snow albedo and the indirect effects of forest litter on snowpack physical properties such as grain size and density);
  3. Evaluate the use of a snow model to inform remote sensing algorithms where detection of snow properties is limited by forest cover;
  4. Recommend strategies for improving remote sensing of snow in forested regions for current and future NASA missions.

It is my pleasure to announce that Travis Roth, PhD candidate in the Water Resources Graduate Program, has been selected to receive a NASA Earth and Space Science Fellowship. HIs project, entitled “Understanding Forest Structure Effects on Snow Accumulation and Ablation for Improved Satellite-Based Snow Mapping and Model Characterization” was one of 73 selected for award out of a total of 425 proposals to the Earth Science Division.

Congratulations Travis!!

Nolin presented her work on ice sheet and sea ice roughness at the 2016 Science Team meeting for the Multi-angle Imaging SpectroRadiometer (MISR).

On Tuesday, Feb. 8th, the NASA/JPL Airborne Snow Observatory collected lidar and hyperspectral data over our Forest Elevation Snow Transect (ForEST) sites. We had a snow survey crew making spectrometer measurements of snow, characterizing snowpack density and depth along our 1-km transects, and characterizing snowpack stratigraphy in snow pits. Spectrometer data were collected on 2/8 when it was cloud-free. Clouds moved in later in the day so no spectrometer data were collected after 2PM on 2/8, none on 2/9.

The non-profit Protect Our Winters (http://protectourwinters.org) sponsored the first POW Athletes’ Summit at Squaw Valley ski resort on Dec. 15-16.

Anne Nolin and Jason Box presented an overview of climate change/climate science for the high profile snowsports athletes.  What a terrific group (and the snow was great too)!!
