New and discontinued parameters
There are many several new parameters, TBC.
Several of the upgrades in CY48R1 have resulted in new parameters, some of which will be added to the dissemination through the Atmosphere Data Store (ADS) and the ECPDS ftp server. For now, the main new parameters are listed in the table below.
