Pairwise Spearman correlations between the number of daily new confirmed COVID-19 cases and meteorological factors and between different meteorological factors in nine countries. The red and blue represent positive and negative correlations, respectively. The color gradient and circle size are proportional to correlation coefficient, and the cross indicates that the statistical test is not significant (P ≥ 0.05). a Portugal; b Greece; c Egypt; d South Africa; e Paraguay; f Uruguay; g South Korea; h Japan. Cases: daily new confirmed COVID-19 cases; Temp: temperature; Prec: precipitation; RelHum: relative humidity; UV index: ultraviolet index; NO2: NO2 total column; Aerosol: ultraviolet aerosol index
