Resolution parameter in MakeModel doesn't work

Open mdd423 opened this issue 3 years ago • 3 comments

Output of MakeModel does not varying with resolution. It doesn't seem like that parameter is added anywhere to the TAPE files.

It seems that ISCAN is set to 0 in the ParameterFile so it shouldn't be convolving within lblrtm. Is there any way to produce higher resolution tellurics? It looks like it's around R~30_000. I am hoping for something closer to R~150_000.

Hmm yeah, from what I recall all the convolutions to reduce resolution are happening in the python code rather than in LBLRTM. So if LBLRTM is not producing high enough resolution, you might be out of luck. I guess you could check their documentation and see if there is a way to increase the resolution? Or maybe we need higher sampling rate on the wavelength grid it generates (I vaguely remember something like that being a parameter - it's been years)

Ok! I will dive into their documentation to try what their limits for resolution are. Thanks, anyways!
