Time Domain Analyte Data
We recommend that analyte files which represent data collected over time use either the APDV or AIDV format and include data for only a single analyte
We do not recommend using the SCT or GWT formats.
When using APDV or AIDV files for time domain data, the following rules apply:
Include data for only a single analyte
Group measurements taken over a few days or even weeks into the same DATE GROUP. If your entire site is re-sampled every 3 months, do not separately list each day when a particular well is sampled.
The "analyte name" for each column of data representing a Date Group should be the average date for that sampling event. The date must be in the Windows standard short date format. In the United States that is typically MM/DD/YYYY (e.g. 11/08/2003 for November 8, 2003)
The data file cannot specify the actual analyte name (e.g. benzene). However, the modules which deal with time domain data have the ability to specify the actual name and units.
Date groups need not be at equal time intervals.
