The sensitivity parameter which is defined as a sum of partial derivatives is calculated with an accurate radiation code applying the 4-stream discrete-ordinates method and the method of exponential-sum fitting for gaseous transmission (ESFT). Microphysical properties of cirrus clouds are parameterized in terms of the cloud temperature from the data of aircraft observations. The value of \u2202H/\u2202[IWC] x \u2202[IWC]/\u2202T, i.e., a product of partial derivatives associated with ice water content feedback, is estimated to be 1.3-2.3 Wm-2\u00b0C-1, meaning a positive feedback effect, and the value of \u2202H/\u2202[SD] x \u2202[SD]/\u2202T which is associated with size distribution feedback is estimated to be -0.1--1.8 Wm-2\u00b0C-1, meaning a negative feedback effect. The positive ice water content feedback is significantly cancelled by the negative size distribution feedback especially at cloud temperature in the vicinity of -45\u00b0C. It is thus shown that the temperature dependence not only of ice water content but also of size distribution is important to estimate the microphysical feedback of cirrus cloud",
