SWEET CryoHackathon sopropst:Snowpack and ENVO:ENVO_03000116 Alignment

[charlesvardeman]

Motivation

In SWEET SnowPack is a subclass of SnowCover which is a subclass of a Thickness of Snow. In ENVO it is integrated with the snow mass hierarchy that implies persistent layering structures over time. SWEET may want to consider the class hierarchy relations

The proposed ENVO URI will be: ENVO:03000116 And the SWEET URI is sopropst:Snowpack
