This Change is in scope of June 2020 Release.

Modification 0659 is working to add into the UNC two new data items to improve the accuracy of the Composite Weather Variable (CWV) – this XRN is seeking to create the mechanism in which the solar radiation and precipitation values will be loaded into UK Link, the approach taken will be done by the CDSP prior to the data being loaded into Gemini so there will be no Gemini requirements as part of this change.
