초록/요약
GWNU (Gangneung-Wonju National University) one-layer solar radiation model is developed in order to resolve the lack of the vertical structure of atmospheric components and fast calculation with high horizontal spatial resolution. GWNU model is based on IQBAL and NREL methods and corrected by precise multi-layer LBL (Line-By-Line) model. Further, the amount of solar radiation reaching the surface by using 42 types of vertical atmospheric data as input data was compared with detailed models and one-layer models. One-layer solar radiation models were corrected depending on sensitivity of each input data (i.e. total precipitable water, ozone, mixed gas, and solar zenith angle). Global solar radiation was calculated by corrected GWNU solar model with satellites (MODIS, OMI and MTSAT-2), KLAPS model prediction data in Korea peninsula in 2010, and the results were compared to surface solar radiation observed by 22 KMA solar radiation sites. Calculated solar radiation annually accumulated showed highest solar radiation distribution in Andong, Daegu, and Jinju regions, meanwhile the observation data showed lower solar radiation in Daegu region compared to model result values. The GWNU (Gangneung-Wonju Nationa University) one-layer solar radiation model, which was corrected using line-by-line and vertical atmosphere data was developed based on the assumption that the ground surface is pane-parallel. GWNU_topo model was improved by taking into account the slope and aspect of the ground surface altitude, using the GWNU model where DEM (Digital Elevation Model) was applied. Using the GWNU_topo model applied the effects of the topography, the solar energy reaching the ground surface for the Korean Peninsula (resolution: 1 km × 1 km) and the Seoul region (resolution: 10 m × 10 m) was calculated. An analysis of the solar energy in relation to the characteristics of the ground surface was conducted. During the winter when the solar altitude is small, there was a big difference of the effect in relation to the topography due to the shielding of the solar energy (1 km × 1 km resolution : maximum ±10% or more, 10 m × 10 m resolution : maximum ±30% or more), while the difference during the summer was small. The higher the resolution for the topography data, the larger the deviation for solar energy. There was no difference in the maximum value of solar energy but due to the effects of the altitude and the slope, the monthly accumulated minimum value was 0.1 MJm-2.
