What are the commonly-used ESA recalling gain and offset coefficient to be used to convert Landsat TM digital number value into radiance value?
For the ESA TM products, it is important to check the calibration method used during the processing and the observation date of the scene. The two tables just here after list the rescaling coefficients in case of pre flight calibration and in case of calibration based on lifetime model. table 2 – TM-4 and TM-5 spectral range values and rescaling coefficient (processing with Pre launch calibration method). There are two samples of rescaling gain/offset coefficients for TM products processed using the lifetime model. The first set of gain/offset coefficients covers a period from the satellite launch to December 31st 1991. The second set gain/offset coefficient covers a period from January 1st 1992 through to the present. The table below lists the TM products scaling coefficients with regards to the observation period.
