Katreen Wikstrom Jones’ strongest reminiscences from her winters rising up in Stockholm, Sweden are constructing snow tunnels on her porch. For the previous ten years, Wikstrom Jones has been in Alaska, working for the state as a cryosphere hazard scientist. She initially obtained into snow science as a result of she loves snowboarding, she says, and at the moment snow is her full time job.
Wikstrom Jones is part of the science workforce for Group Snow Observations. The aim of the citizen science challenge is to extend our understanding of snow depth distribution by growing the variety of floor observations in information sparse areas. These observations will assist validate snow distant sensing information and hydrological fashions – which in the end will present, for instance, water useful resource managers extra correct information to make higher estimates of potential water provide that’s saved in our mountain snowpacks. Contributing as a citizen scientist is simple: It solely requires undisturbed snow, a measuring device and about one minute of your time!
Group Snow Observations (CSO) launched in 2017 with a grant from NASA’s Citizen Science for Earth Science program. Early contributors shaped the mission-critical CSO ambassador workforce: Hydrologists, avalanche professionals, guides, ski patrollers, educators and even Ok-12 academics have been key for selling the challenge in its early years and contributing the primary snow depth observations. It’s since grown into a worldwide citizen science effort with 1000’s of contributors.
Why snow? Snow is sort of a water tower, explains Wikstrom Jones. Snow shops water within the mountains, and impacts everybody and the whole lot downstream when it melts. We want snow for consuming water, for irrigation to help agriculture and for retaining ecosystems wholesome. Understanding snow patterns throughout time and area helps specialists predict ebbs and flows of those vital assets and in addition to foretell hazards like avalanches or floods from snow soften. Snow depth observations from citizen scientists – volunteers of all ages from all around the globe – are tremendously vital for making fashions extra correct, which is more and more vital as our local weather adjustments.

“We’re very captivated with this challenge,” says Wikstrom Jones, “It’s growing tremendously this 12 months, we’ve seen a variety of new observations from all around the world. It’s actually thrilling that [it] retains rising.”
Snow tech
Researchers like Wikstrom Jones create snow fashions to reply a core query: How a lot snow is within the mountains now, that may present water later? In technical phrases, they consider the quantity of water saved in snowpacks as snow water equal. Estimating SWE requires an understanding of each snow depth and snow density throughout the panorama and over time. These fashions are vital as a result of researchers use them to foretell which sectors through which communities will ultimately be affected by the snow.
Making these fashions, and particularly making them extra correct, requires a variety of information. Scientists have snow data going all the best way again to the Thirties that researchers previously collected from monitoring websites scattered throughout the nation. For the reason that Seventies, much more information began being collected from snow telemetry websites – an automatic climate station that collects meteorological information at frequent increments. And in latest many years, tech like drones, airplanes, helicopters and satellites have began to offer distant sensing information that’s nice for mapping out snowpack distribution over an amazing spatial scale.

From backcountry to yard
Group Snow Observations launched when researchers realized how helpful it might be to have citizen scientists collect on-the-ground observations to check with the opposite information they already had about snow. At first, they targeted on recruiting backcountry professionals and recreationists who may take measurements from distant, mountainous places, however they’ve since expanded to ask observations from everybody, wherever with snow.
As we speak, should you see snow, you may take part. You’ll want undisturbed snow, which implies no wildlife tracks, footprints, canine prints or disturbances from snow plows or shoveling. Seize a measurement device: Backcountry followers could have already got a device readily available referred to as a snow probe, which is available in the usual avalanche security equipment, however any ruler, meter stick, yardstick and even measuring tape will do so long as it’s deep sufficient to measure the complete depth of the snow.
Greatest apply is to take three measurements of snow depth, inside a radius of a couple of meter, and averaging them to get a single datapoint to submit. This accounts for the pure variability beneath the snow floor. If there’s any doubt that your measurement device is reaching all the best way to the bottom, dig right down to examine. Lastly, submit your snow depth remark to Group Snow Observations utilizing one in every of their partnering apps! From begin to end, the method solely takes a couple of minutes.
There are a couple of methods to submit your information, and all of them find yourself in the identical place. Select no matter’s best for you.
-
Obtain the app Snow Scope from the app retailer onto your gadget. Choose “snow peak” and submit your measurement (in centimeters). That is the best choice for anybody submitting a distant remark: You should utilize the app to log your remark within the second, which can log your GPS location even should you don’t have cell service. The precise information switch will occur later if you’re again inside service vary.
-
Professionals like to make use of SnowPilot.org, higher on desktops, to submit their observations.
-
In Europe, RegObs is widespread, obtainable as an app or web site.
-
It’s also possible to submit information to the challenge on CitSci.org.
Snow science is for everybody!
Earlier this month, Group Snow Observations logged their 20,521th remark and had their 3,498th particular person person. “That’s actually wonderful,” says Wikstrom Jones. Though their fundamental focus proper now could be the U.S., she says, they’ve obtained observations from Antarctica, Asia and the very southern tip of South America, too.

Since broadening the tasks’ attain past backcountry mountains, the dataset has improved, however so has the group engagement. “It is extraordinarily useful information for the modeling aspect of issues which helps improve snow science and helps present extra dependable merchandise to useful resource managers,” says Wikstrom Jones. “However what now we have realized [after] working CSO now for six years is that it is an amazing studying expertise for contributors as effectively.”
“We get a variety of actually superior suggestions that children are actually having fun with being on the market and recreating and enjoying within the snow, however then you definitely’re including that science element that makes it actually fascinating,” she says. “Our citizen scientists are of us that come from very completely different backgrounds and have very completely different pursuits.”
Need to see their outcomes? Go to MountainSnow.org in your desktop (Wikstrom Jones doesn’t advocate it on cell) to discover a near-real-time mannequin of all of the observations that you would be able to mess around with.
“No one owns science, and we will all contribute to science,” she says, “and with citizen science, we’re actually closing that hole between what historically was known as the general public ‘versus’ the scientific group. It is rather more blurry than that. Science lives in that improbable grey zone between the general public and academia.”
Comply with CSO on Instagram, Twitter, Fb and their web site. Attain out at communitysnowobs@gmail.com if in case you have questions or wish to be related to your native CSO Ambassador.
Submit a snow depth remark to Group Snow Observations between now and February 15, 2023, and you could possibly win a prize!
Let’s begin off this 12 months robust and learn how our mountain snowpacks are stacking up! The principles for this contest are straightforward: We’ll choose the highest 5 winners from the individuals who submit essentially the most snow peak measurements throughout the time interval January 15 – February 15.
