The Portland station was part of the original UO solar monitoring network. It was located at the Ross substation in Vancouver from 1980-1983 (Lat.=45.65; Long.=122.67; Alt.=135 m). In September 1983, it was moved to Reed College (Lat.=45.45; Long.=122.64; Alt.=45 m) until monitoring ended in 1985. In 1999 a new solar monitoring station was established in Gladstone. Links in the table below will take you to more in-depth information about the accuracy of the data collected and the instruments in use.
