Meteorology Output in tdump File

Post by ahazelton » June 17th, 2015, 12:45 pm

Hi,

I am outputting trajectory data interpolated from 15-minute WRF data (interpolated every 1 minute). The tdump file is:

http://moe.met.fsu.edu/~ahazelton/tdump

The problem I am having is that the meteorological variables output (pressure, temperature, theta, RH, qvapor, and mixing ratio) stay the same between the initial point and the first output interpolated point, even though the height clearly changes by several hundred meters between the two times (this was in an area of strong vertical motion). Is there a setting that can be changed to correct this issue?

Thanks,

Andy Hazelton

You will need to set tout = 15, the output frequency in the SETUP.CFG file. Also, make sure that your output frequency is a multiple of your time step. You can set time step with delt = 5 (for instance).

Thanks - if I do that, though, is there a way to get the trajectory data interpolated every 1 minute? That is my issue - I have the 15-minute output but want to get the trajectory data interpolated to 1-minute output.

Thanks again,

Andy Hazelton

Then change the time step to 1 minute and tout to 1.
