However, the applicable area is limited and it cannot treat a heterogeneous atmospheric distribution. We therefore attempted to reduce atmospheric noise using simulation from results of the 10 km-mesh numerical weather model (MSM: Meso-scale model) provided by the Japan Meteorological Agency. A radar propagation path was estimated using the ray-tracing technique in order to consider atmospheric heterogeneity. The average of residual standard deviations for interferograms employed for reducing atmospheric noise was 13 mm, which is almost the same as those for interferograms employed for atmosphere-topography correction. This result suggests that the accuracy of atmospheric delay correction using MSM results is the same level as that of the atmosphere-topography correction. This method is effective since this noise reduction can be applied everywhere in Japan. However, the noise component due to atmospheric heterogeneity could not be reduced, possibly due to inappropriate interpolation for temporal change and/or accuracy of MSM using smoothed topography. We therefore used CReSS, which is a detailed weather model, and estimated the detailed atmospheric data in the observation time. The result reproduced the local atmospheric noise distribution, demonstrating the effectiveness of such an approach."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420001326212884608","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"70455252"},{"@type":"NRID","@value":"1000070455252"},{"@type":"NRID","@value":"9000255735964"},{"@type":"NRID","@value":"9000415352305"},{"@type":"NRID","@value":"9000010317378"},{"@type":"NRID","@value":"9000288834045"},{"@type":"NRID","@value":"9000245918208"},{"@type":"NRID","@value":"9000411392759"},{"@type":"NRID","@value":"9000245917686"},{"@type":"NRID","@value":"9000297496541"},{"@type":"NRID","@value":"9000400160323"},{"@type":"NRID","@value":"9000018697936"},{"@type":"NRID","@value":"9000018698333"},{"@type":"NRID","@value":"9000009965103"},{"@type":"NRID","@value":"9000288834422"},{"@type":"NRID","@value":"9000411392567"},{"@type":"NRID","@value":"9000334418597"},{"@type":"NRID","@value":"9000318561344"},{"@type":"NRID","@value":"9000288834047"},{"@type":"NRID","@value":"9000022057551"},{"@type":"NRID","@value":"9000408782587"},{"@type":"NRID","@value":"9000006182836"},{"@type":"NRID","@value":"9000318561310"},{"@type":"NRID","@value":"9000403425862"},{"@type":"NRID","@value":"9000245917704"},{"@type":"NRID","@value":"9000020970505"},{"@type":"NRID","@value":"9000380981261"},{"@type":"NRID","@value":"9000402599366"},{"@type":"NRID","@value":"9000415352426"},{"@type":"NRID","@value":"9000384265690"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/taku-ozawa"}],"foaf:name":[{"@language":"en","@value":"Ozawa
