Land surface temperature by ward
How hot the ground gets in every ward on clear mornings, each month since 1984, and each summer against the others. Measured from space: the ground (roofs, roads, soil), not the air.
01
What it holds
In more detail
How hot the ground gets: the land surface temperature of every 2026 ward, municipality, district and province each month since 1984, from Landsat (clear mornings only), each summer, and each ward against its municipality. The ground's skin as the satellite sees it, not the air temperature.
How far it reaches
4,759 records: every 2026 ward, municipality, district and province, monthly from January 1984 to 2026-10, with each summer and each ward against its municipality.
How often it changes
Yearly
Yearly after summer (the owner's report: heat once a year, after summer); Landsat 8 and 9 scenes reach Digital Earth Africa's copy within weeks.
Where the figures come from
U.S. Geological Survey, through Digital Earth Africa.
