Abstract: This paper is the first part of research concerning the budget of the atmospheric radiation energy over Eastern Asia. Vie have discussed following three problems: 1.From the experimental values for each band of the absorption spectra of water vapor a formula (6) suitable for hand computation of the absorption of solar radiation,is obtained. It is comvared with Mügge-Moller formula.2. By formula (6), the absorption energy of solar radiation and heating rate from the surface to 100 mb were computed for January and July for 39 station over Eastern Asia. By considering the cloud correction, the absorption of the surface reflection of the radiation by the atmosphere, the distribution of absorption energy of the tropospheric atmosphere over Eastern Asia was obtained.3. Utilizing the data of the surface total radiation and reflection in China during 1958-1960 and the atmospheric absorption energy computed in this paper we have discussed the distribution of planetary albedo in China and the budget of solar radiation energy of the Earth and the atmosphere.
