In addition, we examine the impact of a EUV 121.6 nm time series data source with the DMD control (DMDc) framework, which shows an improvement in the vTEC Root Mean Square Error (RMSE) values compared with the IGS final solution vTEC maps. Both the DMD and DMDc predictions present close RMSE scores compared with the available CODE 1-day predicted ionospheric maps, both for quiet and disturbed solar activity. Finally, we evaluate the predicted global ionospheric vTEC maps with the East-North-Up (ENU) coordinate system errors metric, as an ionospheric correction source for L1 single-frequency GPS\/GNSS Single Point Positioning (SPP) solutions. Based on these findings, we argue that the commonly adopted vTEC map comparison RMSE metric fails to correctly reflect an informative impact with L1 single-frequency positioning solutions using dual-frequency ionospheric corrections.<\/jats:p>","DOI":"10.3390\/rs15020365","type":"journal-article","created":{"date-parts":[[2023,1,9]],"date-time":"2023-01-09T04:47:08Z","timestamp":1673239628000},"page":"365","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Assessment of Dynamic Mode Decomposition (DMD) Model for Ionospheric TEC Map Predictions"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3704-9003","authenticated-orcid":false,"given":"Vlad","family":"Landa","sequence":"first","affiliation":[{"name":"Department of Computer Science, Ariel University, Sciense Park, Ariel 40700, Israel"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8902-5540","authenticated-orcid":false,"given":"Yuval","family":"Reuveni","sequence":"additional","affiliation":[{"name":"Department of Physics, Ariel University, Ariel 40700, Israel"},{"name":"Department of Geophysics, Eastern R&D Center, Ariel 40700, Israel"},{"name":"Astrophysics Geophysics and Space Science Research Center, Ariel University, Ariel 40700, Israel"},{"name":"School of Sustainability, Reichman University, IDC, Herzliya 4610101, Israel"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Afraimovich, E.L., Altynsev, A.T., Grechnev, V.V., and Leonovich, L.A.
