from the Brewer..
Brewer no. 159 has been operational since 15 March 1999, with the
exception of 10-21 November when it went down due to
a computer clock problem. Shown below are daily total ozone and
SO2 values from direct sun (DS) observations,
daily integrated UV values, some parameters related
to the DS and UV observations, and finally the number of
tries and successes for a DS observation (indicative of
cloudiness).
from an Ozone sounding..
Ozone soundings are performed each week, in principle
on wednesdays, using the Vaisala DigiCORA II MW15 system.
Measured values are ozone (nbar), temperature, % humidity and
wind (using satellite GPS).
from the Webcamera..
The webcamera points just north of east and takes pictures every
2 minutes. A couple of them are shown below, along with an animation
compiled from 400 images.

The animation of this day clearly shows how layered and variable the motion in the atmosphere can be here.
