about ZENITH ANGLE in RECORD3.2

[FanliLiu]

Hi, we are writing TAPE5 of LBLRTM to simulate the radiance observed by satellite. But we can't understand the meaning of ZENITH ANGLE in RECORD3.2. Is it the satellite zenith angle? Why should it >90 when H1>H2? Because our satellite zenith angles are generally < 90......and what's the difference between H1 and HOBS when we do "satellite-type simulations"?

@kcadyper i think you can explain this better than i can

Hi,

Zenith angle in LBLRTM is defined as zero for straight up viewing and 180 for nadir. You can ignore HOBS.
