Join Snow View Intensive Observation Period - February, 2025
Snow View: GLOBE Photos of Snow in Clouds, Trees and on Land - February, 2025
The GLOBE
Implementation Office is excited to announce the Snow View Intensive Observation Period (IOP) for
the month of February in conjunction with the NASA Terrestrial
Hydrology Program (THP), the University of Alaska Fairbanks and Oregon
State University. Everyone can learn about snow by observing and
photographing snow with the Cloud, Tree, and/or Land Cover tools on
GLOBE Observer. With a measuring device like a ruler, anyone can
measure the depth of the snow and enter the snow depth in a feature
photo caption.
Share your view of snow—or lack of snow—in your community. Not everyone has your unique view of the snow from your location on Earth.
Snow is part of the local and global water cycle. A snow crystal forms high in the atmosphere in a cloud and falls when it is heavy. As it falls, it may be intercepted by a tree, a structure, or covers the land, where it changes again due to temperature, wind and many factors. Repeat observations in the same location over the month are especially useful. It's easy to make an observation!
How to view snow this February:
1. Choose a GLOBE Observer tool - Land Cover, Trees, Clouds, or the GLOBE Atmospheric Solid Precipitation Protocol
-
Record time
-
Record geographic location
-
Answer surface condition questions (Is there ice or snow?)
2. Take photos according to the GLOBE Observer tool or GLOBE protocol
-
In GO Land Cover tool, add a feature photo with or without snow.
-
In GO Land Cover tool, add a caption that includes snow depth and units used
3. Optional - GLOBE Members and Educators trained in the GLOBE Atmosphere Precipitation protocol, follow the Solid Precipitation Protocol Field Guide.
-
Use a ruler or meter stick to measure and enter total snow depth data in millimeters.
-
Use a GLOBE rain gauge to measure liquid equivalent of the total snow (also called snow water equivalent) in millimeters.
-
If you have a snow board, follow the field guide to enter the depth, amount of water and the pH of new snow.
4. Join webinars on February 6 @ 10 am ET, February 20 @ 10 am ET, and February 26 @ 4 pm ET. More info and to register here https://www.globe.gov/web/snow-view/overview
Students can do snow research along with NASA SnowEx Intern Julia White. See how in this recorded 8 minute video for students and teachers: https://youtu.be/NFHq2xS0ZnQ
What will the Snow View team do with all the data from this Intensive Observing Period?
By viewing snow photos from the GLOBE Observer App in February, the Snow View team hopes to explore some of the following research questions that relate to the water cycle:
-
Is the snow extent (coverage) similar to prior years?
-
Does the snow accumulate in interesting ways because of the landscape?
-
Can satellite remote sensing be used to find and estimate the size of snow drifts?
-
How does wind transport snow from trees and from the ground in the same location over time?
-
What color is the snow?
Snow and remote sensing scientists are invited to join the GLOBE International STEM Network conversation at 20 February 2025 @ 10 am ET (3:00 pm UTC). Register here: https://brooklyn-cuny-edu.zoom.us/meeting/register/tZUufuiurDMiGtQjyNHLJ9oheMUepbE3DraN#/registration
