degree_days

This response option uses the Population Weighted HDDs and Population Weighted CDDs endpoints. It does not accept a model. The model and initialization time are inherited from the system-emitted degree_days.available event, and both complete endpoint responses are placed in data.response .

Configuration Options

There are no response-specific configuration options for degree days.

Subscription Behavior

Subscription	Attached response
degree_days.available	The complete HDD and CDD endpoint responses for the triggering model initialization.

Response Fields

Field	Type	Description
hdds	object	The complete Population Weighted HDDs response for the triggering model and initialization time.
cdds	object	The complete Population Weighted CDDs response for the triggering model and initialization time.
