Hi Aleksandar,

I don't think anyone has responded to your email below, so I am responding, in 
part, so it doesn't get lost in the recent blizzard of emails on other topics 
:-).

I still much prefer the alternative that was proposed:

   time_sample_interval_due_to_collocation

I think this is less ambiguous, will be easier to understand for someone who 
doesn't know what you are trying to represent, and easier to generalize in the 
future.

I suggest that we tweak the description to improve clarity:

"The difference in time between two events that are collocated. Two events are 
deemed to be collocated based on some set of spatial, temporal, and viewing 
geometry criteria."

I also checked on the spelling of 'collocation'.    Unfortunately, different 
dictionaries seem to disagree, with varying support given to:  collocation, 
colocation, and co-location.  In the dictionaries I looked at, collocation was 
often described as a literary term (for two words appearing next to each 
other), with colocation and co-location often being more clearly defined in the 
way that we want.  But it was not clear cut.  Is there consensus in the fields 
relevant to CF?
        
Best wishes,

    Philip

Subject: Re: [CF-metadata] New Standard Names for Satellite Data

Does anyone wants to comment further on the standard name below? It's been 
almost three weeks since I provided the definition.

Standard name: collocation_time_interval

Definition:
The temporal difference between two measurement events being collocated. 
Collocation is a process in remote sensing of grouping two independent 
measurements based on a set of spatial, temporal, and viewing geometry criteria.

Units: s
