Solar radiation is emitted in the wide frequency range from gamma to radio emission. Hence, joint observations from different instruments and frequency ranges let us to complete full representation of the evolution of solar events and confirm authenticity of data from specific instruments. In this article, we present comparative analysis data from Solar Spectropolarimeter of Meter Range wavelengths (SSMD) and other instruments. For the investigation we have chosen three solar events registered with SSMD in 2019: type III radio bursts on May 6 from 05:05 UT to 05:12 UT, type II radio bursts on May 6 from 05:12 UT to 05:19 UT, and type III radio bursts on April 14 from 05:03 UT to 05:21 UT. For comparison we apply data from the following instruments: SSMD, SRH (Siberian Radioheliograph), SDO/AIA (Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO)), Wind/WAVES (WAVES investigation on the WIND spacecraft), ground-based spectropolarimeter AMATERAS, spacecraft GOES-14. As a result, we can conclude that they are in good correlation with each other and correspond to outstanding characteristics for each event. The investigation also confirms the SSMD data authenticity.
