Based on solar irradiance data published by Neckel and Labs (1984) and Iqbal (1983), the solar exoatmospheric irradiances for Thematic Mapper (TM) bands 1, 2, 3 and 4 have been calculated. Results vary by up to 1 per cent from our previously published values which were based on earlier data of Neckel and Labs. For TM bands 5 and 7, integrated solar exoatmospheric irradiances have also been recalculated using solar irradiance data published by Labs and Neckel (1968), Arvesenet al. (1969) and Iqbal (1983). These irradiances vary by up to 6 per cent from our previously published results, which were based on data published by Thekaekara (l972).
