The non-linear effect in the linear calibration curve induces a deviation of 1.5 degrees (k) of brightness temperature in the tenth channel (8.3 um, water vapor absorption) of the HIRS/2 and the non-linear effect affects the other channels to a different extent. Based on analyzing non- linearity in two-point calibration curve, a tri-point calibration equation is given. A numerical test of effects of the linear and non-linear calibration models on the accuracy of atmospheric temperature retrievals is carried out.展开更多

The writer＇s findings through literature review of the issues in the teaching and learning of ESL/EFL oral English indicate that further studies in this area may provide more valuable experiences to aid ESL/EFL speakers in producing fluent and accurate speech.展开更多
