Simulated brightness temperatures (SBT; coloured lines), as functions of the electrical skin depth, for various values of TI in the range 5−320 JK−1 m−2 s−0.5 (SI units). The black dotted lines represent the MBT from the millimetre and submillimetre receivers for September 1, 2014 at 23:48. The millimetre SBT curves with TI values less than 10 JK−1 m−2 s−0.5 intersect the millimetre MBT line; and the submillimetre SBT curves with TI values less than 80 JK−1 m−2 s−0.5 intersect thesubmillimetre MBT line.
