The data was then combined and statistically analysed to produce an average heat hazard value (peak temperature) for every 30 metre square at multiple time points throughout the year.
Wedyn, cafodd y data hyn eu cyfuno a'u dadansoddi'n ystadegol i greu gwerth perygl gwres cyfartalog (tymheredd uchaf) ar gyfer pob 30 metr sgwâr ar nifer o bwyntiau amser drwy gydol y flwyddyn.
