Please update the following fields and click "Display" to see the model BUFKIT pressure gradients. You can click on the Seattle, Portland, or Spokane sites buttons to populate common gradient pairs. Note that the IDs are required to match the BUFKIT site (eg, KSEA, UIL, KGEG, SMP, CWLW, WJA), and they must be readily available (you can check the available sites at the Iowa State or Penn State BUFKIT pages). The two sites in a pair are separated by a comma or dash (,-) and the pairs are separated by slashes (/). For example, "KPDX-KBLI/KOLM-KSEA/UIL-KBLI/KAST-KPDX". Observed pressure gradients will be included below the model pressure gradients. The URL will automatically update with the new settings.
