Which is the conversion factor for calibration information? - rese_support - 30-Sep-2014 For some sensors the calibration coefficients are specified with the unit [W m[sup]-2[/sup] sr[sup]-1[/sup] micron[sup]-1[/sup]] in the metadata file. In this case, the calibration data has to be multiplied by 0.1 to obtain the correct units [mW cm[sup]-2[/sup] sr[sup]-1[/sup] micron[sup]-1[/sup]]. Usually, the data are already calibrated and scaled by a constant factor (in order to fit into a 2byte Integer), which needs to be accounted for in the calibration constants. Example: if this scaling factor is 1000 from [mW cm[sup]-2[/sup] sr[sup]-1[/sup] micron[sup]-1[/sup]], the calibration constant c1 is 1e-3. |
