The Oklahoma Atmospheric Surface-Layer Instrumentation System (OASIS) enhanced 89 of the Oklahoma Mesonet stations with new sensors to enable routine measurements of the surface energy budget including: net radiation, ground heat flux, sensible heat flux, and skin temperature. Additionally, latent heat flux can be estimated as the residual of the surface energy balance. As part of the project, additional soil moisture sensors were installed at depths of 5, 25, 60, and 75 centimeters.
Dates : April 1999 - December 2007
Data were collected every 5 minutes and observations are in UTC time.

Most of the stations in the Oklahoma Mesonet stations that were active from April 1999 - December 2007 had OASIS upgrades. For a list of stations, please visit the Oklahoma Mesonet Sites webpage.
