You can combine (aggregate) data selected from a Working or Master table in space and time to form a new data series that can be stored in a Working table. For example, you can compute new records that contain the mean of all values recorded in each calendar month. You can also optionally spatially aggregate data, to compute the average monthly values in each EcoRegion.
A special aggregation period "Four Seasons (Annual Summary)" is available which will combine data using the indicated operation (mean, median, etc.) for each of the four seasons. If data for all four seasons are present, these will then be combined to comput an annual vaulue which will then be added to the output table. The 'Sort by Date-Time' report is the best way to output these new data.
