Station map Obstruction for the global horizontal illuminance sensor

Comments For the vertical illuminances, a half hemisphere obstruction was made with a black honeycomb material. The direct solar illuminance and direct solar irradiance sensors are mounted on a solar tracker. All the illuminance photocells and the irradiance sensors were calibrated at EKO Instruments Trading Co. in May 1991.
