Initial Request
----------------------------------------------------------------
Dear Met_help
We have been running WRF for some time for historic TC simulation and was wondering if the MET tool could be useful for verification. We often experience that only a few observation are available so was hoping that the tool would enable us to use satellite pictures for 2 d verification of tracks and structures
Do you have any material on MET usage on TC verification
Which techniques
Wavelet?
Which data sources
Past satellite images avaible
Scatterometers etc
Are looking forward to hear from you and getting starting on this tool
Cheers

Subject: general quistions on MET for TC
From: John Halley Gotway
Time: Mon Feb 04 09:35:01 2019
Dr. Nissen,
I see that you have a question about how the MET software can be used
for
the evaluation of tropical cyclones. Several years back we added 3
new
tools to MET to replicate the verification methods used by the United
State's National Hurricane Center. The MET-TC tools (tc_dland,
tc_pairs,
and tc_stat) are really focused on the evaluation of hurricane track
and
intensity via data in the ATCF file format.
For example, a typical data flow would include...
- run an NWP model, such as WRF or HWRF to model a tropical cyclone
- run the output through a tracker, such as GFDL vortex tracker (
https://dtcenter.org/HurrWRF/users/downloads/index.tracker.php), which
produces ATCF output files
- use MET-TC to compare the forecast ATCF to the BEST track (or
another
model's ATCF output) using the MET tc-pairs tool
- summarize results across multiple storms/initializations using the
tc-stat tool
- MET also includes a sample R-script which can be used to
read/filter/plot
the output of tc_pairs
As for comparing model output to other gridded datasets, there are
other
tools in MET which enable grid-to-grid comparisons, such as grid-stat
and
mode. The question is whether or not the input data is readable by
MET.
While some satellite data is, others are not. For those that are not,
we
enhanced met-8.0 to read input gridded data via Python. So you should
be
able to use Python to pass any sort of input data you'd like.
Also, we're doing more development in 2019 to use track data to
transform
gridded TC data into the "radius-of-maximum-winds" (RMW) space. And
you
may be interested in the results of that.
I'd encourage you to go through the MET online tutorial for more
details:
https://dtcenter.org/met/users/support/online_tutorial/METv8.0/index.php
Hope that helps.
Thanks,
John Halley Gotway

Thanks John
Sounds good
I will give it a try - Working on a ubuntu system and was wondering if
I could use the Docker if I want to avoid the pain of building from
Scratch ?

Dr. Nissen,
Sure, you're welcome to use the Docker option. Please let me know how
it
goes.
FYI, here's a tutorial about doing end-to-end modeling and
verification
using MET and METviewer via Docker. You may find the example useful.
Here's the overview of it:

Thanks John
It looks very useful indeed - Good a Typhoon project the next 6 weeks
so will give the Docker-container version of met a try !
Cheers
