AB: Surface albedo, the ratio of upward solar radiation reflected by the surface over the downward solar radiation, is an important parameter to determine the surface radiation budget and thus the global mean surface temperature. Apparently, increase in surface albedo can be found in the area where the white plastic greenhouses are widely used by farmers during the rent decade. Such increase will reduce the radiation absorbed by the surface and then the surface temperature. Hence, greenhouses covered with white plastic can reflect more solar radiation and reduce the warming effect of greenhouse gases. In this paper are presented some field measurements of surface albedo and reflectance spectrum over different surfaces, particularly over the greenhouses.
