EQUATESv1.0: Emissions, WRF/MCIP, CMAQv5.3.2 Data -- 2002-2019 US_12km and NHEMI_108km

<h1>Data Summary:</h1>
<b>EQUATES: EPA’s Air QUAlity TimE Series Project</b><br>
The US EPA developed a set of modeled meteorology, emissions, air quality and pollutant deposition spanning the years 2002 through 2019. Modeled datasets cover the Conterminous US (CONUS) at a 12km horizontal grid spacing (12US1) and the Northern Hemisphere at a 108km (108NHEMI) using WRFv4.1.1 for meteorology and CMAQv5.3.2 for air quality modeling. New hemispheric and North American emissions inventories were developed using, to the extent possible, consistent input data and methods across all years, including emissions from mobile, fire, and oil and gas sources. Collectively these model outputs represent 100s of TB of data. We have selected a subset of the model input and output datasets that we hope will be most useful to the air quality research community. <br>

These datasets include:
<ul><li> 2002-2017 monthly and annual emissions totals for 9 pollutants: NOX, SO2, CO, PM2.5, primary organic carbon (POC), primary elemental carbon (PEC), VOC, non-methane organic gases (NMOG), NH3</li>
<li>Emissions inventory files for the CONUS for 2002-2019 suitable for input into the Sparse Matrix Operator Kernel Emissions (SMOKE) emission processor</li>
<li> CMAQ-ready emissions, initial conditions and boundary condition input files for the 12US1 domain for 2013-2019</li>
<li> CMAQ-ready meteorology files for the 12US1 domain for 2002-2019. </li>
<li> Matched surface meteorology model output with surface observations for 2002-2019 </li>
<li> Daily average CMAQ estimated concentration for 14 pollutants for the 12US1 domain for 2002-2019 </li>
<li> Annual total CMAQ estimated deposition (wet and dry) for the 12US1 domain for 2002-2019 </li>
<li> Daily average 3D CMAQ output for 44 layers for the 108NHEMI domain for 2009–2019</li></ul>

<b>Note: The 2002-2017 emissions summary files are included as part of this Dataverse repository as zipped comma separated ASCII files. (Note, 2018 and 2019 emission summary data are not included in this repository but can be downloaded from this <a href="https://drive.google.com/drive/folders/10Q75NC1q6Y0AU2FS1Bz_e8wU9UubGh4B?usp=drive_link">CMAS Google Drive folder</a>.) This repository also includes two zip files with the CMAQ source code used for running CMAQ on the 12US1 and 108NHEMI domains. The remaining modeling datasets are on either the Google Drive or the AWS Open Data Program. The metadata associated with this DOI contain the link to the Google Drive folder and instructions for downloading the modeling data. </b>
