    • ID = Snake River Plateau
    • WA = Columbia River Plateau
  • Long Term data - Long term distributions of tropospheric transmission loss
    • Data access for Long Term data has not yet begun.

To install the Profile Plot Program (PFL_PLOT) for Windows-95/98/NT/2000 download PFL_PLOT.exe and install from your hard drive.

README.txt file describes installation procedures.
