Data are presented for 6 days, before and after a large rainstorm (39 mm), which illustrate how evaporation from the bush vegetation changed little in comparison with the larger change in evaporation observed over the bare soil. Net radiation over the bush vegetation was 20 per cent greater than that over the dry bare soil, but only 12 per cent greater than that over wet bare soil. These differences are consistent with the expected difference in albedo and surface temperature of the two surfaces Royal Meteorological Society 1990 Article PeerReviewed application/pdf en http://oar.icrisat.org/7139/1/International%20Journal%20of%20Climatology_10_2_203-210_1990.pdf Wallace, J S and Gash, J H C and Sivakumar, M V K (1990) Preliminary measurements of net radiation and evaporation over bare soil and fallow bushland in the Sahel.
