[CF-metadata] use of the "trajectory" discrete sampling geometry for a hurricane intensity product

From: Randy Horne <rhorne>

For the "trajectory" discrete sampling geometry, the data design pattern for the data and coordinate variables are:

data(index, observation)

x(index, observation)
y(index, observation)
z(index, observation)


The hurricane product grows with a new hurricane intensity value is added every 30 minutes.

For this product, the simplest thing to do is increment the index for each new hurricane intensity value. Given this the data and coordinate variables look like:

data(index)

x(index)
y(index)
z(index)

This looks like a "point" discrete sampling geometry even though it is a trajectory.

Would a hurricane intensity product designed like a point discrete sampling geometry but identified as a trajectory (cf_role = "trajectory_id") be in conformance with the CF conventions ?
