     >The CF metadata conventions are designed to promote the processing and sharing of files created with the NetCDF API. The conventions define metadata that provide a definitive description of what the data in each variable represents, as well as the spatial and temporal properties of the data. This enables users of data from different sources to decide which quantities are comparable and facilitates building applications with powerful extraction, regridding, and display capabilities. The CF convention includes a standard name table, which defines strings that identify physical quantities.
 
-    CF metadata conventions set common expectations for metadata names and locations across datasets.  In this tutorial, we will use tools such as [cf_xarray]() that leverage CF conventions to add programmatic handling of CF metadata to Xarray objects, meaning users can spend less time wrangling metadata.

 Spatio-temporal Asset Catalog (STAC)
     STAC is a metadata specification for geospatial data that allows the data to be more easily "worked with, indexed, and discovered" [$\tiny \nearrow$](https://stacspec.org/en). It does this by setting a standard format for how metadata will be structured. This functions like setting a common expectation that all users of the data can rely on so that they know where certain information will be located and how it will be stored.

 ##### 2. Compare two datasets by combining them into a single cube with an additional dimension
 - To compare data from different satellites within the ITS_LIVE dataset, we create a new data cube with a `'sensor'` dimension ([*ITS_LIVE tutorial, notebook 4 - exploratory analysis of a single glacier*](../itslive/nbs/4_exploratory_data_analysis_single.ipynb)*).

+- Adding `source` dimension when comparing ASF and PC backscatter datasets ([*Sentinel-1 tutorial, notebook 5 - comparing backscatter datasets*](../sentinel1/nbs/5_comparing_s1_rtc_datasets.ipynb)).  
     - In this example, the goal of our analysis changes from observing backscatter to observing how measurements of backscatter from two processing pipelines differ from one another. This implies a different shape of the data that is relevant to this question; the appropriate dimensions change from `(x, y, time, band)` to `(x, y, time, band, source)`. 
     - Adding a source dimension let's us index the combined dataset by 'source' and compare the two 'source' elements on a common grid and scale.
