As the #WintersUnderPressure course in Oulanka 2026 is coming to an end, I think it is worth posting a bit about how fun and full of learning the week has been.
We have had students with many different backgrounds 🧪👩‍🔬🦠and they have shined the whole week ❄️

Why the Northeast blizzard's snow is ideal for snowballs and snowmen School is out as heavy, wet snow blankets parts of the Northeast. Though it will be a pain to shovel, it makes for perfect snowballs and the most structurally sound snowmen

Why wet, heavy snow is the best for making snowballs and snowmen #Science #EarthSciences #Meteorology #SnowScience #WeatherPatterns #WinterFun

Yes, we are out in the snow on purpose.

Our technicians are collecting snow core samples to quality-check our SWE sensors—because “looks right” is not a measurement.

Check us out on insta! @nysmesonet

A tiny, but mighty, snowpack for this season's #snowpit training day. Every season we train our skills in doing a snow pit analysis. We do this because some parts of the analysis are subjective, so we try to "calibrate" our evaluations of the characteristics. #SHaM #SnowScience #MastersOfThePit

Investigating KDP signatures inside and below the dendritic growth layer with W-band Doppler radar and in situ snowfall camera Abstract. Polarimetric radars provide variables like the specific differential phase (KDP) to detect fingerprints of dendritic growth in the dendritic growth layer (DGL) and secondary ice production, ...

❄️ Snowfall study!

W-band radar and snowflake images show high KDP can arise from turbulence, blowing snow, small crystals, and surface dendritic aggregates—not just heavy snowfall.

Targeted snow monitoring at hotspots outperforms basin-wide surveys in predicting water supply Measuring mountain snowpack at strategically selected hotspots consistently outperforms broader, basin-wide mapping in predicting water supply in the western United States, a new study has found.

🏔️ Secret snow hotspots, not wide maps, unlock the West's water future! 🤔 Focused monitoring = surprisingly accurate supply predictions.💧 #SnowScience

Latitudinal gradients of snow contamination in the Rocky Mountains associated with anthropogenic sources Seasonal snow is an important source of drinking water and recreation, and for agriculture in the Rocky Mountain region. Monitoring snow-water quality…

🏔️💧 Polluted snow in the Rockies?

New research shows northern Rocky Mountain snow is contaminated with heavy metals like mercury and cadmium – mainly from mining and smelting.

The Cloud Seeding Team made it back to the same spot near Lake Tahoe and the #snowpack looks much better after a full night of DRI water resource enhancement operations! Thank you to Jesse for sharing this update! ❄️ #SnowScience #ScienceThatMattersNow

Honored to have joined the 9th EGU #SnowScience Course in France!

💧❄️ We measured LWC, stratigraphy, density, SSA, albedo, SWE, Smp & more @ fieldwork

🧊Inspired by the brilliant international team and the pressing need 🥵 to study snow's role in Earth's climate, Water cycle, Glaciers & Icesheets 🫠.

#SNOWSCHOOL SUCCESS!
Some 250 local fifth graders received hands-on instruction on #SnowScience from @sierra4ever.bsky.social , #FriendsoftheInyo, #WinterWildlandsAlliance , local school districts & volunteers this month. Go to sierraforever.org/blog to read our media release & share it w/ others.

Ideal dendrites today! Perfect snowflakes form in calm winds, -12°C to -18°C temps, high humidity, and a stable atmosphere. These conditions let them grow symmetrically and fall intact! #Weather #SnowScience

15 years ago, I captured this above #Innsbruck. The PR agency of #Tirol bought it for their campaign, printing posters seen in many Innsbruck homes.

Now? As an expert in microbial snow and ice ecology, I could talk about the science for hours too! 🏔️❄️
