[Met_help] [rt.rap.ucar.edu #52487] History for chemistry data

[Paul Oldenburg via RT]

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

To Whom It May Concern:

I understand that MET is mainly for the meteorology community for model evaluation but still want to ask if current MET has the capability of bringing in the chemical data from various sources (e.g., AIRNOW, IMPROVE, and other database) and comparing with model simulation? If so, how to accomplish this?

Thanks for your attention,

Zhining Tao

Zhining,

It should be possible to use those datasets with MET, assuming that
you can get the forecast and observation data into a
format that MET can read.  For forecast data, the best path would
probably be to post-process your model data using the
Unified Post Processor (UPP) to produce GRIB files.  For the
observation data, you may want to use the ascii2nc tool to
ingest data in ASCII format.  This may require some experimentation to
make sure that the GRIB code and level type of
the observation can be used to match with the appropriate field in the
model data.  If you have any further questions
about this, please let me know.

Thanks,

Paul

Paul,

Thank you for the answer. Here comes another question. Can MET somehow
take the results from a trajectory model (e.g., HYSPLIT) and evaluate
against observation? In other word, is MET a tool for Lagrangian model
evaluation at all?

Thanks,

Zhining

Zhining,

MET was designed to perform verification on standard atmospheric
variables like temperature and humidity.  It will
likely not support the type of verification you have in mind.
However, if you want to try, you need to format your
model data into one of the supported input types for MET: GRIB or
p_interp.  Once you perform this step, you can use MET
to verify any gridded scalar in your model data.  Please let me know
if you have any other questions.

Paul
