The Lamont TCCON weather station is located in Lamont, Oklahoma, at the Southern Great Plains Central Facility, the first field site established by DOE's Atmospheric Radiation Measurement (ARM) Program. Measurements have been taken every second since the system was activated in July, 2008.
The system collects and archives information about temperature, solar radiance, precipitation, wind, humidity, and barometric pressure.
You can see a graph of the full data archive or look up data by day.
A webcam mounted on top of the TCCON container provides a view of the skies over Lamont. The feed is updated every hour.
