-> [!CAUTION]
-> The IceFlow notebooks and supporting code have some known problems and users
-> should exercise caution. It is likely that users will run into errors while
-> interacting with the notebooks. Requests for ITRF transformations are not
-> currently working as expected. We recommend users look at the `corrections`
-> notebook for information about how to apply ITRF transformations to data
-> themselves. IceFlow is currently under maintenence, and we hope to resolve
-> some of these issues soon.

-These Jupyter notebooks are interactive documents to teach students and researchers interested in cryospheric sciences how to access and work with airborne altimetry and related data sets from NASA’s [IceBridge](https://www.nasa.gov/mission_pages/icebridge/index.html) mission, and satellite altimetry data from [ICESat](https://icesat.gsfc.nasa.gov/icesat/) and [ICESat-2](https://icesat-2.gsfc.nasa.gov/) missions using the NSIDC **IceFlow API**
