VNP46A2 / Black Marble data

1. Is it appropriate to use the data to compare the ‘night’ activity of regions which have shorter vs longer daylight hours? (e.g. in certain winter months, Norway experiences 6-8 hours of daylight whereas Singapore has ~12 hours of daylight throughout the year) Or is the data processing able to account for this?
2. If certain country experiences a significant event e.g. armed conflict in a winter month (presumably with shorter daylight hours) and the conflict is reported to have ended in a summer month (longer daylight hours), do you see any issues with using nighttime light emissions data to observe changes/recovery in activity? Or would taking an average radian metric be sufficient?
