 ### 1.1 NetCDF metadata
 
 Metadata enables users of data from different sources to decide which quantities are comparable, and facilitates building applications with powerful extraction, regridding, and display capabilities.
 
-To facilitate this process, there are conventions for CF (Climate and Forecast) metadata. These are designed to promote the processing and sharing of files created with NetCDF. The conventions define metadata that provide a definitive description of what the data in each variable represents, and the spatial and temporal properties of the data. Learn more about the CF metadata conventions [here](http://cfconventions.org).

 ### 2.2 Variables of the ERA5 atmospheric reanalysis
 
 ERA5 is the fifth generation ECMWF atmospheric reanalysis of the global climate covering the period from January 1940 to present. ERA5 is produced by the Copernicus Climate Change Service (C3S) at ECMWF. ERA5 provides hourly estimates of a large number of atmospheric, land and oceanic climate variables.
 
-A full list of ERA5 parameters is available on the [ECMWF database](https://codes.ecmwf.int/grib/param-db/). It covers both the [ERA5 parameter listings](https://confluence.ecmwf.int/display/CKB/ERA5%3A+data+documentation#ERA5:datadocumentation-Parameterlistings) as well as the [ERA5-LAND parameter listings](https://confluence.ecmwf.int/display/CKB/ERA5-Land%3A+data+documentation#ERA5Land:datadocumentation-parameterlistingParameterlistings).
