ADEM Timerange Parameter

Autonomous DEM APIs provide a timerange query parameter. The timerange that you supply is in human readable format:


For example:


The responses are aggregated over a sample period which is a function of the time interval requested, such that the granularity decreases with increasing interval. This keeps the number of sample returned to a reasonable number whilst still allowing higher resolution at small intervals.

Interval (days)Sample Period (minutes)
<= 15
<= 315
<= 730
<= 1460
<= 21120

Alternately, you can specify an exact time range using the start and end query parameters. These accept Unix timestamps. For example:
