First, I should say that only the air quality side of AMET currently will function without a database present. So, you won’t be able to use AMET to process and analyze meteorological data with the database.
You can use AMET-AQ without a database present. The AMET User’s Guide explains how to do this. I suggest referring to that guide for more detailed instructions of what I will explain here.
In short, to analyze air quality data without the database, you’ll skip any steps that require a database. That includes initial setup of the AMET database, creating an AMET database user, etc. In the AMET-AQ example run scripts in the scripts_db directory, you’ll want to set the LOAD_SITEX flag in those scripts to “F”. This will tell AMET not to load any data into the database. In the analysis scripts in the scripts_analysis directory, you need to set the AMET_DB flag to “F”. This tells AMET to read the observed/modeled data directly from the site compare csv files and not the database.
Note that not all AQ analysis scripts will currently work without the database present, but many will. Please report any issues you run into. This is a new feature in AMETv1.4 and I’m looking for feedback.
Thanks and good luck!
