Der zugrunde liegende Datensatz für dieses Produkt für die Nacht ist MODIS-Daten zur Landoberflächentemperatur (MOD11A2), die mit dem in Weiss et al. (2014) beschriebenen Ansatz aufgefüllt wurden, um fehlende Daten aufgrund von Faktoren wie Wolkenbedeckung zu eliminieren. Die lückenlosen Ausgaben wurden dann zeitlich und räumlich aggregiert, um das monatliche Produkt mit einer Auflösung von etwa 5 km zu erstellen.
Dieses Dataset wurde von Harry Gibson und Daniel Weiss vom Malaria Atlas Project (Big Data Institute, University of Oxford, Vereinigtes Königreich, https://malariaatlas.org/) erstellt.
