The COVID-19 pandemic in Korea by the end of September 2020: (A) Timeline of the COVID-19 pandemic in Korea and Jeju from January 1, 2020 to September 30, 20201; (B) Province-level distribution of cumulative COVID-19 confirmed cases in Korea by September 30, 2020 2; (C) COVID-19 indicators and Google Trends Index from January 1, 2020 to September 30, 2020, including case fatality rate in Korea (the percentage of people who die from COVID-19 among all individuals confirmed with the disease in Korea), daily new cases in Korea, daily new cases in Jeju, Google Trends Index of the search term “COVID Korea”, and Google Trends Index of the search term “COVID Jeju”.

A schematic plot of the implementation of block kriging on top of the Thiessen polygon generated from the soil moisture stations (numbered 1–15). When spatial autocorrelation was detected, block kriging is used to remove the autocorrelation, using Thiessen polygons as blocks for the areal interpolation (blue indicates low soil moisture content and red indicates high soil moisture content), rather than point/pixel-based interpolation.
