Abstract
The technique of space infrared and microwave atmospheric sounding with ATOVS instrument is discussed. The results of the sounding are vertical profiles of atmosphere. Zenith tropospheric delay was estimated with the profiles and with the Saastamoinen and Hopfield delay models using surface measurements. Biases of the model-derived estimations are -0,0186 m for the Saastamoinen model and -0,0135 m for the Hopfield one during the whole 2012. The results are valid for Krasnoyarsk (middle latitudes of Siberia).
