ITS_LIVE is a dataset of ice velocity observations derived from applying a feature tracking algorithm to pairs of satellite imagery. Ice velocity refers to the down-slope movement of glaciers and ice sheets {cite}`Gardner_Scambos_2022`. Because glaciers and ice sheets are dynamic elements of our climate system, they lose or gain mass in response to changes in climate conditions such as warmer temperatures or increased snowfall, measuring variability in the speed of ice flow can help scientists better understand trends in glacier dynamics and interactions between glaciers and climate.

Part of what is so exciting about ITS_LIVE is that it combines image pairs from a number of satellites, including imagery from optical (Landsat 4,5,7,8,9 & Sentinel-2) and synthetic aperture radar (Sentinel-1) sensors. For this reason, ITS_LIVE time series data can be quite large. Another exciting aspect of the ITS_LIVE dataset is that the image pair time series data is made available as Zarr data cubes stored in cloud object storage on Amazon Web Services (AWS), meaning that users don't need to download massive files to start working with the data!

ITS_LIVE produces a number of data products in addition to the image pair time series that we use in this tutorial, and provides different options to access the data. Check them out [here](https://its-live.jpl.nasa.gov/#access).

abstract={ NASA's ITS_LIVE project delivers information on global glacier dynamics and provides historical context for climate change with a record of how every glacier in the world has evolved over decades of satellite observation. To handle petabytes of data in the satellite archives and a constant influx of new observations, the project has adopted a cloud-native approach that is scalable, performant, user friendly, and embraces transparent and collaborative code development. As every discipline of Earth science is being transformed by a new era of remote sensing and cloud computing, ITS_LIVE offers a progressive approach to maximizing scientific advancements through open science. },
