albedo/XCE pairs are somewhat
representative of conditions at
different times in a typical shot.
high values for late time and the low
for early times.The intermediate case (low albedo, high XCE) was used to investigate the relative effects of these two parameters on the overall TRand also on the relative DANTE and witness plate values.
between DANTE and the witness plate are large when the beam pointing is not so deep, but they are closer when the
pointing is deeper;
•The radiation temperature on the witness plate
exceeds that on DANTE for these deeper pointings when the albedo is relatively low.
•Lowering the albedo significantly lowers the
radiation temperature in the halfraum, even if the XCE is kept high.
