Use Case 7

###Compute a time series

Use Case: Compute a time series
Actor: Climate/Data Scientist
Details: A lot can be told by simply averaging a region together (el nino, global ,Northern hemisphere) this is typically a drop in dimensionality. Read a spatial region and return a single point.
Use Scenario:

1. identify need file(s) to cover time period
2. identify non-time dimensions
3. average over non-time dims, be careful if user want to average, them in specific order or all at once (get different results if missing values)
4. dump out result

Difficulties: order of averaging does matter when missing values, keeps weights around between each round
Alternative Path: single location, difference between 2 location (North Atlantic Oscillation, etc...)
Exceptional Cases:
Frequency: Medium
Criticality: Medium
Risk: Medium
