        <gco:CharacterString>NDGD Air Quality Forecast Guidance for one hour average ozone concentration. Concentration units are parts per billion. For further information please visit our website at 

. This is a time enabled image service with WMS and WCS capabilities enabled. Forecast guidance is issued twice daily based on 6Z and 12Z model runs. Forecast information is provided in one hour intervals for the subsequent 48-hour period. Client applications may require users to specify time range parameters to view time sliced or loop data.
