Research Abstract

We newly installed a millimeter-wave radiometer at Rio Gallegos, Argentina, located near the Antarctica, and started continuous measurements of the vertical distribution of ozone in the stratosphere for evaluating ozone depletion in the mid-latitude region caused by transport of the airmass inside the ozone hole. The vertical profile of ozone has been retrieved from the spectrum observed with the radiometer every 5 minutes, and has been validated by comparisons among the measurements with an ozone LIDAR and other instruments.
