What are the commonly-used ESA recalling gain and offset coefficients to be used to convert Landsat ETM + digital number value into radiance value?
A set of lower and upper spectral radiances is provided for each band. In the case of Landsat 7 ETM+, this set differs from one gain state to the other one. In tables here below are illustrated the spectral radiance limits as well as their correspondent gain and offset. table 4 – ETM+-7 spectral range values in low gain mode. table 5 – ETM+-7 spectral range values in high gain mode. Q23. We are conducting a study on numerous European Landsat 5 and 7 products acquired between 1984 and 2003. We would like to work with spectral radiance values. Could you let me know if the calibration values for each band (Gain and offset) have been changed during these scenes acquisition period? For the whole European Landsat 5 and 7 products, the gain and offset values to be applied are unchanged. On September 1,1986, EOSAT adjusted look-up tables (LUT) for TM bands 5 and 7. Adjustment methods and results are fully explained in the following document: Markham, B.L., and J.L. Barker, 1986, Landsat MSS an
