The solar brightness temperature at millimeter wavelengths

The authors have previously discussed an improved method for obtaining the absolute solar brightness temperature by using the new Moon as a calibration source. New measurements of the Sun-to-new Moon ratio at three frequencies near 36 GHz ( lambda = 8 mm) and, also, at two frequencies near 93 GHz (...

Description
Summary:The authors have previously discussed an improved method for obtaining the absolute solar brightness temperature by using the new Moon as a calibration source. New measurements of the Sun-to-new Moon ratio at three frequencies near 36 GHz ( lambda = 8 mm) and, also, at two frequencies near 93 GHz ( lambda = 3 mm) are reported. The slopes of the solar brightness temperature spectrum based on these ratios are then discussed. The absolute solar brightness spectrum derived from all current available measurements is presented and discussed.
