Abstract Using the data derived from the "2004 Jinta Oasis System Energy and Water Cycle Field Experiment（JTEX）”, a simulation of surface radiation balance over the Jinta oasis has been worked out with the MM5 mesoscale model. The research results show that meteorological and radiation fields of the oasis-desert system can be well simulated. The results also indicate that short wave radiation and net radiation in the oasis and desert have obvious diurnal variation, while it is not very obvious for long wave radiation. The downward short wave radiations in desert and oasis are similar with the maximum of approximately 1 050 W·m-2. While the maximum of upward short wave radiation in oasis is small at about 166 W·m-2, which in desert is 261 W·m-2. Meanwhile, the difference between long wave radiation in desert and that in oasis is not large, and the value of radiation is around 300 W·m-2 all day. The maximum of net radiation in oasis with about 914 W·m-2 is larger than that in desert with about 800 W·m-2. The net radiation on the same underlying surface is almost of the same and is distributed uniformly, and the difference in the same underlying surface is no more than 10 W·m-2. Whereas the difference in different underlying surface is large during the day and the most difference is near 100 W·m-2.
