Soo much Snow ...and Ice

January 05, 2018


2018 began with freezing temperatures across 90% of the US.  

The Northeast is currently experiencing a massive winter snowstorm, referred to as a "bomb cyclone"Boston is experiencing record cold temperatures not felt since 1884. And, it is not just New England - a majority of the rest of the country is also currently being affected by the brutal cold; this includes Texas, Georgia and Florida, even. 

What is happening? Why is this happening now? Could it have something to do with climate change? Dr. Ulyana "Uly" Horodyskyj uses ASD's FieldSpec HandHeld 2 VNIR spectroradiometer to attempt to answer these questions. Uly studies snow and ice, collecting data on albedo, and conducting research on how NIR analysis can help identify snow and ice reflectance properties, including spectral radiance and light-absorbing impurities (LAI) such as black carbon/dust. 


Educating others is also a large component of Uly's work. In fact, she collaborated with ASD, sharing her research on our Adventures in Albedo Webinar in 2016. In 2017, Uly was featured for her project work in The Himalayas, educating sherpas on glacial health and their changing environment... you can watch her "Sherpa Science Initiative - Documenting Climate Change with Citizen Science" video here (see the HandHeld 2 in action at 4:05 and 6:12!)  

The ability to accurately perform field reflectance and radiometric measurements is critical to climate research. ASD’s FieldSpec® line of spectroradiometers offers multiple configuration options for measurements above and below the snow and ice surfaces. FieldSpec spectroradiometers are frequently used by researchers to perform the requisite field measurements for remote sensing assessments of snow cover and to calculate the key criteria for surface energy balance modeling of snow-covered and glaciated areas.
