Developer Information: Service Units

Service Units (SUs) are a measure of the requested volume of data. One SU is defined as one physical parameter recorded at one observing station at one point in time. For example, a query that requested the air temperature and wind speed from 4 stations at 3 points in time would return a data volume of 24 SUs (2 parameters x 4 stations x 3 points in time).
