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 date: 1990 date_type: published publication: International Journal of Climatology volume: 10 number: 2 publisher: Royal Meteorological Society pagerange: 203-210 refereed: TRUE issn: 1097-0088 official_url: http://dx.doi.org/10.1002/joc.3370100207 related_url_url: http://scholar.google.co.in/scholar?as_q=Preliminary+measurements+of+net+radiation+and+evaporation+over+bare+soil+and+fallow+bushland+in+the+Sahel&as_epq=&as_oq=&as_eq=&as_occt=title&as_sauthors=&as_publication=&as_ylo=&as_yhi=&btnG=&hl=en&as_sdt=0%2C5 related_url_type: pub citation: 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.
