Data from ground station have limited spatial representation and accuracy, which can be overcome using satellite-based Earth Observation (EO) recordings instead. EO-based meteorological recordings can help to provide a better understanding of the correlations between meteorological variables and dengue cases. This paper aimed to first validate the satellite-based (EO) data of temperature, wind speed, and rainfall using ground station data. Subsequently, we aimed to determine if the spatially matched EO data correlated with dengue fever cases from 2011 to 2019 in Malaysia. EO data were spatially matched with the data from four ground stations located at states and districts in the central (Selangor, Petaling) and east coast (Kelantan, Kota Baharu) geographical regions of Peninsular Malaysia. Spearman\u2019s rank-order correlation coefficient (\u03c1) was performed to examine the correlation between EO and ground station data. A cross-correlation analysis with an eight-week lag period was performed to examine the magnitude of correlation between EO data and dengue case across the three time periods (2011\u20132019, 2015\u20132019, 2011\u20132014). The highest correlation between the ground-based stations and corresponding EO data were reported for temperature (mean \u03c1 = 0.779), followed by rainfall (mean \u03c1 = 0.687) and wind speed (mean \u03c1 = 0.639). Overall, positive correlations were observed between weekly dengue cases and rainfall for Selangor and Petaling across all time periods with significant correlations being observed for the period from 2011 to 2019 and 2015 to 2019. In addition, positive significant correlations were also observed between weekly dengue cases and temperature for Kelantan and Kota Baharu across all time periods, while negative significant correlations between weekly dengue cases and temperature were observed in Selangor and Petaling across all time periods. Overall negative correlations were observed between weekly dengue cases and wind speed in all areas from 2011 to 2019 and 2015 to 2019, with significant correlations being observed for the period from 2015 to 2019. EO-derived meteorological variables explained 48.2% of the variation in dengue cases in Selangor. Moderate to strong correlations were observed between meteorological variables recorded from EO data derived from satellites and ground stations, thereby justifying the use of EO data as a viable alternative to ground stations for recording meteorological variables. Both rainfall and temperature were found to be positively correlated with weekly dengue cases; however, wind speed was negatively correlated with dengue cases.<\/jats:p>","DOI":"10.3390\/ijerph19116449","type":"journal-article","created":{"date-parts":[[2022,5,26]],"date-time":"2022-05-26T08:50:22Z","timestamp":1653555022000},"page":"6449","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["The Effects of Meteorological Factors on Dengue Cases in Malaysia"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6602-1758","authenticated-orcid":false,"given":"Sarbhan","family":"Singh","sequence":"first","affiliation":[{"name":"Institute for Medical Research, Ministry of Health, Shah Alam 40170, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7032-0363","authenticated-orcid":false,"given":"Lai Chee","family":"Herng","sequence":"additional","affiliation":[{"name":"Institute for Medical Research, Ministry of Health, Shah Alam 40170, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5840-8450","authenticated-orcid":false,"given":"Lokman Hakim","family":"Sulaiman","sequence":"additional","affiliation":[{"name":"Institute for Research, Development and Innovation (IRDI), International Medical University, Kuala Lumpur 57000, Malaysia"},{"name":"School of Medicine, International Medical University, Kuala Lumpur 57000, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shew Fung","family":"Wong","sequence":"additional","affiliation":[{"name":"School of Medicine, International Medical University, Kuala Lumpur 57000, Malaysia"},{"name":"Centre for Environmental and Population Health, Institute for Research, Development and Innovation (IRDI), International Medical University, Kuala Lumpur 57000, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenarun","family":"Jelip","sequence":"additional","affiliation":[{"name":"Vector Borne Disease Control Division, Ministry of Health Malaysia, Putrajaya 62000, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norhayati","family":"Mokhtar","sequence":"additional","affiliation":[{"name":"Vector Borne Disease Control Division, Ministry of Health Malaysia, Putrajaya 62000, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quillon","family":"Harpham","sequence":"additional","affiliation":[{"name":"HR Wallingford, Wallingford OX10 8BA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gina","family":"Tsarouchi","sequence":"additional","affiliation":[{"name":"HR Wallingford, Wallingford OX10 8BA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0738-2991","authenticated-orcid":false,"given":"Balvinder Singh","family":"Gill","sequence":"additional","affiliation":[{"name":"Institute for Medical Research, Ministry of Health, Shah Alam 40170, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2856","DOI":"10.1017\/S095026881400380X","article-title":"Testing the impact of virus importation rates and future climate change on dengue activity in Malaysia using a mechanistic entomology and disease model","volume":"143","author":"Williams","year":"2015","journal-title":"Epidemiol.
