Visibility Grid                                Help                                              Regional Haze Data Set Information
Display a color coded table highlighting the best and worst 20% sampled visibility days at IMPROVE monitoring sites.
  • Select sites, years and months from the selection boxes. Note: Sites are order by geographical region. Selections that include 2000 will return all calendar days (as well as IMPROVE sampling days). Dates will be returned as a date range.
  • Output can be formatted to display sites as columns or dates as columns.
  • The grid display can show either B for Best 20% visibility day and W for Worst 20% visibility days, or the deciview (dv) value.  In the grid, the best 20% days are colored green, the worst 20% days red, and missing sampling days (MI) yellow.
