CAOS has a very active field
experiment group and has made measurements both over land and ocean.
There are two automatic weather stations (AWS) within the IISc campus
and another one at Vengurla in Maharastra. The Lab has modern surface
flux sensors including sonic anemometer, IR Hygrometer, pyranometer and
pyrgeometer. Vaisala Radiosonde receiver system with GPS wind capability
enables probing the vertical structure of the atmosphere.
SODAR and
RASS for measuring the temperature and wind velocity of the
atmospheric boundary layer, LIDAR for measurements of aerosol vertical
profiles and a host of instruments for surface aerosol measurements.
