Resolution enhancement by differential saturation at −10°C (130 kG/s). A) Raw NARS spectra collected under non-saturating (-32 dB), moderate saturating (-20 dB), and saturating conditions (-8 dB). B) NARS spectra collected at two microwave powers, adjusting the amplitude of the lower power to account for the expected amplitude difference due to the change in microwave power (dashed). C) The difference of the black spectrum from the dashed green spectrum in Panel B in shown in red. MDIFF was applied to the red spectrum to enhance turning points in the lower trace.
