Notes:

• The zoom function only works in conjunction with the station identifier, not with the pre-defined regions.
• Zooming in by 40% or more will also plot various city names on the maps.
• If not all of the date/time fields are specified, the latest available data will be used.
• For loops, the date/time specifird will be the end time of the loop.
• All loops consist of 25-frames and can be selected to cover a either 4-HR, 12-HR, or 24-HR periods.
• Loops take about 10 seconds to build.
• Data are updated at approximately 5 minute intervals and data are kept on our server for about 15 days.
