Solar-radiation-maintained glacier recession on Kilimanjaro drawn from combined ice-radiation geometry modelling
[1] In the context of investigating modern glacier recession on Kilimanjaro, which began around 1880, this study addresses the glacier regime of the vertical ice walls that typically form the margins of Kilimanjaro’s summit glaciers. These walls have suffered a continuous lateral retreat during the...

[1] In the context of investigating modern glacier recession on Kilimanjaro, which began around 1880, this study addresses the glacier regime of the vertical ice walls that typically form the margins of Kilimanjaro’s summit glaciers.
