 **Harmonized data for  pre-IceBridge, ICESat and IceBridge data sets.**
 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**

 ## Summary
 
 The IceFlow python library simplifies accessing and combining data from several of NASA's cryospheric altimetry missions, including ICESat/GLAS, Operation IceBridge, and ICESat-2. In particular, IceFlow harmonizes the various file formats and georeferencing parameters across several of the missions' data sets, allowing you to analyze data across the multi-decadal time series.
