2019 ICESat-2 Cryospheric Hackweek Projects

A brief list of the projects (and links to their repositories on GitHub) worked on at the 2019 Hackweek are below. These projects are also tagged with the 2019-project tag in the University of Washington ICESat-2 Hack Week GitHub organization.

Crackup: Glaciersat2: Ground2float Segtrax: Snowblower: Topohack:

Python Libraries

• icepyx: Originally icesat2py, the icepyx library initially began as a Hackweek project designed to bring together code accomplishing similar tasks (e.g. data access and read-in)

Sea Ice

• Floes are Swell: Calculate chord length (CLD) and lead width (LWD)

• Segtrax: Create trajectories of sea ice motion (creates Python trajectory class). (video of presentation)

Glaciers and Ice Sheets

• Crackup: Investigating small-scale features such as crevasses and water depth (video of presentation).

• GlacierSat2: Constrain surface types (e.g. wet vs. dry snow) using ICESat-2 data over the Juneau Icefield, working towards looking at seasonal elevation changes. (video of presentation)

• WaterNoice: Detection of hydrologic features (e.g. meltwater ponds, firn aquifer seeps, blue ice megadunes, icebergs, etc.) in ATL06 land ice product

• SnowBlower/blowing snow: Evaluate the blowing snow flag and look at blowing snow models. (video of presentation)

• Cross-trak (xtrak): Interpolation between ICESat-2 tracks; create gridded elevation data from multiple ICESat-2 tracks

• Ground2Float: Identify grounding zones using ICESat-2 data (using the slope-break method). (video of presentation)

• Topohack: resolve topography over complex terrain. (video of presentation)
