The Oklahoma Mesonet is an automated environmental observing system distributed over the state of Oklahoma. There are 114 stations providing observations every 5 minutes. Data are collected and transmitted to a central point every 15 minutes where they are quality controlled, distributed and archived.

Each station consists of a 10 m tower providing measurements of air temperature (1.5 m), relative humidity (1.5 m), wind speed and direction (10 m), barometric pressure, rainfall, solar radiation, and soil temperature (10 cm for both sod and bare soil).

About half the stations provide supplemental measurements of air temperature (9 m), wind speed and direction (2 m), leaf wetness, soil moisture (5, 25, 60 and 75 cm under sod), and soil temperature (5 and 30 cm under sod and 5 cm under bare soil).

Data files from the Mesonet are copyrighted. SGP97 investigators will have access to all data for 1997 via the Goddard Distributed Active Archive Center (DAAC). However, these data may not be redistributed. Additional information on the Mesonet can be found on a web page at
