Podstawowym zbiorem danych dla tego produktu nocnego są dane o temperaturze powierzchni lądu MODIS (MOD11A2), które zostały uzupełnione przy użyciu metody opisanej w artykule Weiss i wsp. (2014) w celu wyeliminowania brakujących danych spowodowanych takimi czynnikami jak pokrywa chmur. Dane wyjściowe bez luk zostały następnie zagregowane w czasie i przestrzeni, aby uzyskać miesięczny produkt o rozdzielczości ok. 5 km.
Ten zbiór danych został opracowany przez Harry’ego Gibsona i Daniela Weissa z Malaria Atlas Project (Big Data Institute, University of Oxford, Wielka Brytania, https://malariaatlas.org/).
