The system allows retrieval of hourly, daily or monthly data from a combination of FAA, NWS and "ECONET" weather stations across the region. Most of the Econet (formerly AGNet) stations include evaporation measurements. These are not done using pans, but an automated instrument that should replicate pan evaporation reasonably well.

Here, the Econet sites are indicated by green dots. You can select one by clicking the "Info" button and then clicking on the station of interest. More directly, you can go to a Raleigh site called "Reedy Creek" by using the address below, and can select a different Raleigh site along Lake Wheeler road by changing "REED" to "LAKE" in the address below.
