This dataset includes both surface and profile data that are AERMOD ready. USAF site ID at surfuce site is used as file names. All airport surface sites was processed with 2009-2013 surface data and upper air sounding data at the site that is the nearest to the surface site with the following exceptions in Mojave Desert air district: 723805R - with upper air data at Tuscon, AZ (WBAN: 23160); 747188R - with upper air data at Tuscon, AZ (WBAN: 23160); 723815R - with upper air data at Desert Rock, NV (WBAN: 03160) for 1/1/2009 - 11/26/2010; 723815RR - with upper air data at Las Vegas, NV (WBAN: 03120) for 12/15/2010 - 12/31/2013; 690150R - with upper air data at Desert Rock, NV (WBAN: 03160) for 1/1/2009 - 11/26/2010; 690150RR - with upper air data at Las Vegas, NV (WBAN: 03120) for 12/15/2010 - 12/31/2013; 723825R - with upper air data at Desert Rock, NV (WBAN: 03160) for 1/1/2009 - 11/26/2010; 723825RR - with upper air data at Las Vegas, NV (WBAN: 03120) for 12/15/2010 - 12/31/2013; 746120R - with upper air data at Desert Rock, NV (WBAN: 03160) for 1/1/2009 - 11/26/2010; (located in Kern County APCD) 746120RR - with upper air data at Las Vegas, NV (WBAN: 03120) for 12/15/2010 - 12/31/2013. AERMET Version 14134 was used to generate all data files. BETA u‐star adjustment was not used in the processing. AERSURFACE was used to generate 6-sector, monthly surface characteristics. ASOS data were not used, and AERMINUTE was not used.
