Landing Page
Kept the same information as original design--just made more organized and visually appealing
Researchers who are interested in datasets only can now access data directly from button on landing page
Map Page
The Snow Lab has several research stations and snow courses--the Map Page provides graphs and datasets of all facilities
Users can select snowfall reports from different time periods
Following rounds of low and mid-fidelity iterations, we produced final prototypes to support a seamless handoff to the developers on the team.

Ideation
Following our synthesis process, our team create low-fidelity mockups to visualize new layouts and features for CSSL’s website.

Background
The UC Berkeley Central Sierra Snow Lab (CSSL) has been a leader in snow, climate, and hydrology research for over 75 years, maintaining the world’s longest continuous snowfall record. Our project focuses on redesigning their digital platform into a modern, data-driven website with interactive tools, real-time visualizations, and an improved admin workflow to better support researchers, collaborators, and the public.
Problem
CSSL’s Current Website Interface
CSSL’s current website and data tools are outdated, difficult to navigate, and lack modern visualization capabilities. This makes it challenging for researchers, collaborators, and the public to easily access real-time snow and climate data. The lab needs a clearer, more intuitive digital interface that streamlines data management, improves usability, and accurately reflects the impact of their scientific work.
HMW Statement
How might we redesign CSSL’s digital platform to make real-time snow and climate data easier to access, understand, and manage?






Context
Research
Competitive Analysis
First, we conducted competitive analysis of multiple organizations to identify effective patterns and pitfalls, drawing insights to brainstorm CSSL’s pages and features.
Due to the project scope and timeline, our research was intentionally limited to prioritize delivering a hi-fidelity prototype for developer implementation. Despite this, we are confident that the methods we chose provided the necessary insights to effectively redesign CSSL’s website.
User Interviews
We asked 10 users (a mix of students, researchers and journalists) of the Snow Lab website about their experiences using the websites and what they thought could be improved. The main feedback we received was:
The data graphics imagery were outdated
There were too many tabs on some pages, leading to confusion
There was an inconsistent layout across different pages, leading users to be disoriented
There was a lack of graphics & imagery
They would prefer more interactivity elements on some pages, because it is currently not engaging
Important Quotes from Users:
“Its just a lot all at once and its hard to see what to focus on”
“There are way too many words”
“It’s hard to find what I want because it’s very disorganized”

Reflection

I had an amazing time working on this project alongside my team members. I especially loved how much creative freedom this project gave us as it was a complete website redesign, which allowed us to explore ideas through many iterations. While working on the history timeline in particular, I learned how important it is to communicate closely with developers throughout the design process. It is essential for designers to consider what features can realistically be implemented within technical and time constraints.
I am so grateful for this lovely team as we had such a collaborative and rewarding experience! I also want to thank the CSSL team for trusting us with this website redesign.
