Abstract The atmospheric boundary layer (ABL) is an important parameter for the study of climate, weather forecasting, dispersion studies/Air Pollution Modeling. SODAR (SOund Detection And Ranging) is a remote sensing technique for continuous monitoring of ABL height. Very limited studies in the literature on the SODAR data validation done by using Satellite data. However, the accuracy of the ABL Satellite data in comparison to the ground-based SODAR measured ABL data is always questionable. In the present paper, ABL height from the MERRA-2 model data (Modern Era Retrospective-analysis for Research and Application, Version 2 M2TMNXFLX v5.12.4) is compared and validated with the SODAR observed ABL data over Delhi region. From the preliminary study and analysis, it has been found that the coefficient of determination (R) was 0.48 between the SODAR data and MERRA-2 data of ABL Height. It is also observed that it is possible to predict the ABL height from the MERRA-2 model data. Additionally, the result shows that the SODAR ABL height data can be predicted by from the MERRA-2 model data and vice versa.
